How To Hire Dedicated Software Development Team

We all have been agreeing that we need to take the help of top talent to fulfill the requirements of our complex tasks at some business point. Sometimes, your in-housing team fails to match client’s requirements, or we can say market needs. At that moment, you need to take one step forward and hire dedicated software development team to match the client’s requirements and market trends. Before going ahead, take a look at the dedicated development team model.

When you are going to do a partnership with a software development company, a dedicated software development team is one method. On the other hand, fixed price and time are other models. Every model has its uniqueness, benefits, and drawbacks. Let’s talk about a dedicated development team.

When clients look for a dedicated team for software development, they want to hire a team of developers to fulfill the tasks of the complex project. That team of developers collaborates with the in-housing squad, although they work remotely. They take responsibility for the project and try to make the project successful. They dedicate themselves to match all requirements of the project in the market or the latest trends.

How To Hire Dedicated Software Development Team

Dedicated software development team - Talents

  • Backend and frontend developers
  • Project manager
  • Business analysts
  • DevOps
  • UX/UI designers
  • Quality assurance engineers

When hiring a development team is a Good Choice?

  • When you have some complex project, and the in-housing team is inexperienced.

  • When you don’t have a resource of the dedicated web development team to match the complexity of your projects.

  • When you want to take your business to the next level in terms of client satisfaction and expertise.

  • When you have multiple projects aligned with the same deadlines, a software development dedicated team is an excellent choice to go with.

  • When you don’t have enough time to hire a team of developers for your in-house.

  • When you expand your business with a dedicated software development team, they take care of your specific needs and reach out to all the possible and desired objectives.

Benefits of outsourcing a dedicated team

Because of the following reasons, you need to hire development teams for your business.

Cost-effectiveness
When looking for a dedicated development team for hire, you do not require to spend your valuable time hiring IT specialists individually and forming a team. You also not needed to build an infrastructure for them. They will work remotely with their resources, so there is no additional cost. They can start working on your project by the time you hire dedicated team, and there is no delay or settlement needed.

Focus on the projec

The software dedicated development team you hire does the work for only your project during the set time period. So, their full focus is solely on your project.
You can also check the work process and get updates regarding your project regularly. This collaboration takes your project to the next level and provides the best satisfaction to the clients.

Flexible approach

A dedicated development team is the best choice for large-scale projects. It gives you one benefit: if you require more developers between the projects or want to cut down your team size, you can do it. Dedicated developers are very flexible; they take any issues and react to get the best output accordingly.

Maximum effect and speed

They understand your business goals and understand the importance of matching deadlines. They keep track of work progress, so they can give you the reports of completed tasks and future outlines if you ask. You will get maximum efficiency and high speed with a dedicated team for software development.

After knowing the advantages of developers outsourcing dedicated teams, we are now going to look at how to hire dedicated software development team.

How to hire dedicated software development team?

Hire a development team for your organization is a stressful task for organizations as you need to focus on several factors. I know it is a crucial task for your organization, but stress, you do not need to think about. A few ways are available to hire a dedicated software development team for your organization, like finding them from Google organic search or B2B portals.

Narrowing down your search, and select partner through:

  • Google top 10 result
  • B2B portal (Clutch)
  • Freelance workplaces (Upwork)
  • StackOverflow
  • GitHub

How to Set-up, a dedicated software development team?

After choosing your offshore partner, now it’s time to follow the process for setting up your dedicated development team.

Well-defined business objectives are needed.

You need to explain all your business requirements, including the deadline and desired workflow you wanted, development team size, and type of expertise you require.

**Assembling the team **

Individual hiring can take one or more months, but with a dedicated team model, you bring your team to your work within one week.

Talent selection

After finding a dedicated team, selected the best-qualified team for your project with factors like expertise, efficiency, tech skill, English fluency, and other aspects of your project.

Integrating the team

After selecting the team based on your skills requirements, the group joins the project in progress quickly. Now, we can say business owners take the best step to get a business boost soon in the market.

Criteria that you need to look at while hiring a dedicated team.

With this model, you hire a development team and start working on your project like your in-housing team. For making any product successful, you must have to look for the right developers and team members. Here we will look at a few criteria you need to keep in mind while hiring a dedicated development team.

Portfolio: Take note that whether the team you are hiring is proved the portfolio or not

Reviews: Take a look at the reviews of that dedicated team.

Skillset: Make sure the dedicated team matches all the skills you require.

Language: Take note that the dedicated team has a good command of language.

Cost: Make sure the decided price is not beyond your budget.

The number of members: Based on your project deadline, decide the number of developers you require.

Cách Xuất Một Hàm Từ C ++ Sang React Native

Hôm nay, tôi tiếp tục chia sẻ kinh nghiệm của mình với Native Module và C ++.

Vì chúng ta sẽ thấy rất nhiều thư viện C / C ++ viết cho nền tảng di động, chúng ta cần triển khai chúng cho ứng dụng iOS hoặc React Native của mình. Đó là lý do mình muốn viết một bài hướng dẫn cách export một hàm từ C ++ sang React Native dễ hiểu và tiết kiệm thời gian cho người mới bắt đầu. Tôi sẽ bắt đầu với một ứng dụng gốc phản ứng mới

1. Tạo một ứng dụng gốc phản ứng mới, mở thiết bị đầu cuối của bạn và chạy

npx react-native init NativeModules

2. Mở Xcode và điều hướng đến NativeModules / ios / NativeModule.xcworkspace

3. Làm việc trên C ++

Tạo một tệp C ++ mới và đặt tên cho nóCpp_to_RN.cpp

Khi chúng tôi tạo tệp C ++ mới, Xcode sẽ tạo tệp tiêu đề Cpp_to_RN.hpp cho chúng tôi

Đầu tiên, mở tệp Cpp_to_RN.hpp“” và tạo một lớp bao gồm một hàm không có phần thân.

#ifndef Cpp_to_RN_hpp
#define Cpp_to_RN_hpp#include <stdio.h>
#include <string>class Cpp_to_RN {
public:
    std::string sayHello();
};#endif /* Cpp_to_RN_hpp */

Sau đó, mở Cpp_to_RN.cpptệp và viết một hàm đơn giản “ sayHello()

#include "Cpp_to_RN.hpp"
std::string Cpp_to_RN::sayHello(){
    return "Hello from CPP";
}

4. Thao tác trên Wrapping C ++ file.

Để bọc các tệp C ++ và xuất chúng sang phía IOS (nhanh chóng)

một. Tạo một tệp Objective C và đặt tên cho nóCpp_to_RN.m

Đổi tên Cpp_to_RN.m thành Cpp_to_RN.mm

b. Mở WrapCpp_to_RN.mm tệp và viết nội dung phần nội dung sẽ bọc hàm sayHellotừ tệp C ++.

#import <Foundation/Foundation.h>
#import "WrapCpp_to_RN.h"
#import "Cpp_to_RN.hpp"@implementation WrapCpp_to_RN- (NSString *) sayHello {
  Cpp_to_RN fromCPP;
    std::string helloWorldMessage = fromCPP.sayHello();
    return [NSString
            stringWithCString:helloWorldMessage.c_str()
            encoding:NSUTF8StringEncoding];
}
@end

c. Tạo một tệp tiêu đề và đặt tên cho nóWrapCpp_to_RN.h

Xuất wrapSayHellohàm sang tệp Swift

#import <Foundation/Foundation.h>
@interface WrapCpp_to_RN : NSObject
- (NSString *) wrapSayHello;
@end

5. Làm việc trên iOS (Swift)

Để xuất hàm C ++ sang React Native

một. Tạo một tệp Swift và đặt tên cho nóSendCpp_to_RN.swift

Lưu ý: Xcode sẽ yêu cầu chúng tôi tạo một NativeModules-Bridging-Header.htệp cho chúng tôi.

Tạo một lớp SendCpp_to_RNvà khai báo nó làNSObject

#import <Foundation/Foundation.h>
@interface WrapCpp_to_RN : NSObject
- (NSString *) wrapSayHello;
@end

Viết một hàm requiresMainQueueSetup()để ngăn cảnh báo khi chúng tôi chạy ứng dụng

#import <Foundation/Foundation.h>
@interface WrapCpp_to_RN : NSObject
- (NSString *) wrapSayHello;
@end

Viết một hàm để bọc WrapCpp_to_RN()từWrapCpp_to_RN.mm

import Foundation@objc(SendCpp_to_RN)
class SendCpp_to_RN : NSObject {
    
  @objc static func requiresMainQueueSetup() -> Bool {
        return false
    }
  
  @objc func fromCpp(_ successCallback: RCTResponseSenderBlock) -> Void {
    successCallback([NSNull(), WrapCpp_to_RN().wrapSayHello() as Any])
    }}

b. Xuất một hàm bọc trong tệp Swift sang React Native

Tạo một tệp Objective C để xuất lớp Swift và chức năng của nó bằng cách sử dụngCallback

#import <React/RCTBridgeModule.h>
#import <Foundation/Foundation.h>
#import "UIKit/UIKit.h"
@interface RCT_EXTERN_MODULE(SendCpp_to_RN, NSObject)RCT_EXTERN_METHOD(fromCpp:(RCTResponseSenderBlock)successCallback)@end

c. Kết nối Swift với React Native, mở NativeModules-Bridging-Header.h tệp

#import <React/RCTBridgeModule.h>#import <React/RCTViewManager.h>#import "WrapCpp_to_RN.h"

6. Làm việc ở phía React Native

Gọi lớp Swift và các chức năng của nó

import React from 'react';
import {StyleSheet, Text, View, NativeModules, Button} from 'react-native';const App = () => {
  const onPress = () => {
    const {SendCpp_to_RN} = NativeModules;
    SendCpp_to_RN.fromCpp((_err, res) => console.log(res));
  };
  return (
    <View style={styles.container}>
      <Text> Practice !</Text>
      <Button title="C++ to React Native" color="#841584" onPress={onPress} />
    </View>
  );
};
const styles = StyleSheet.create({
  container: {
    flex: 1,
    justifyContent: 'center',
    alignItems: 'center',
  },
});
export default App;

Và chúng tôi đã hoàn tất, chỉ cần chạy ứng dụng

react-native run-ios

Hoặc chỉ cần nhấp vào nút “chạy” trên Xcode và xem những gì chúng tôi đã làm.

Tôi hy vọng bài viết của tôi hữu ích cho bạn, cảm ơn bạn đã dành thời gian đọc.

Cómo Exportar Una Función De C++ A React Native

Hoy sigo compartiendo mi experiencia con el Módulo Nativo y C++.

Dado que veremos muchas bibliotecas C/C++ escribiendo para las plataformas móviles, debemos implementarlas en nuestra aplicación iOS o React Native. Por eso quiero escribir un artículo sobre cómo exportar una función de C++ a React Native, que es fácil de entender y ahorra tiempo a los principiantes. Comenzaré con una nueva aplicación nativa de reacción.

1. Cree una nueva aplicación nativa de reacción, abra su terminal y ejecute

npx react-native init NativeModules

2. Abra Xcode y vaya a NativeModules/ios/NativeModule.xcworkspace

3. Trabajando en el lado de C++

Cree un nuevo archivo C++ y asígnele un nombreCpp_to_RN.cpp

Cuando creamos un nuevo archivo C++, Xcode creará un archivo de encabezado Cpp_to_RN.hpp para nosotros

Primero, abra el archivo " Cpp_to_RN.hpp" y cree una clase que incluya una función sin el cuerpo.

#ifndef Cpp_to_RN_hpp
#define Cpp_to_RN_hpp#include <stdio.h>
#include <string>class Cpp_to_RN {
public:
    std::string sayHello();
};#endif /* Cpp_to_RN_hpp */

Luego abre el Cpp_to_RN.cpparchivo y escribe una función simple “ sayHello()

#include "Cpp_to_RN.hpp"
std::string Cpp_to_RN::sayHello(){
    return "Hello from CPP";
}

4. Trabajando en el archivo Wrapping C++.

Para envolver los archivos C++ y exportarlos al lado IOS (swift)

una. Cree un archivo Objective C y asígnele un nombreCpp_to_RN.m

Renombrar el Cpp_to_RN.m a Cpp_to_RN.mm

b. Abra el WrapCpp_to_RN.mm archivo y escriba el contenido del cuerpo que envolverá la función sayHellodel archivo C++.

#import <Foundation/Foundation.h>
#import "WrapCpp_to_RN.h"
#import "Cpp_to_RN.hpp"@implementation WrapCpp_to_RN- (NSString *) sayHello {
  Cpp_to_RN fromCPP;
    std::string helloWorldMessage = fromCPP.sayHello();
    return [NSString
            stringWithCString:helloWorldMessage.c_str()
            encoding:NSUTF8StringEncoding];
}
@end

C. Cree un archivo de encabezado y asígnele un nombreWrapCpp_to_RN.h

Exportar la wrapSayHellofunción al archivo Swift

#import <Foundation/Foundation.h>
@interface WrapCpp_to_RN : NSObject
- (NSString *) wrapSayHello;
@end

5. Trabajando en el lado de iOS (Swift)

Para exportar la función C++ a React Native

una. Cree un archivo Swift y asígnele un nombreSendCpp_to_RN.swift

Nota: Xcode nos pedirá que creemos un NativeModules-Bridging-Header.harchivo para nosotros.

Crear una clase SendCpp_to_RNy declararla comoNSObject

#import <Foundation/Foundation.h>
@interface WrapCpp_to_RN : NSObject
- (NSString *) wrapSayHello;
@end

Escribir una función requiresMainQueueSetup()para evitar advertencias cuando ejecutamos la aplicación.

#import <Foundation/Foundation.h>
@interface WrapCpp_to_RN : NSObject
- (NSString *) wrapSayHello;
@end

Escriba una función para envolver el WrapCpp_to_RN()fromWrapCpp_to_RN.mm

import Foundation@objc(SendCpp_to_RN)
class SendCpp_to_RN : NSObject {
    
  @objc static func requiresMainQueueSetup() -> Bool {
        return false
    }
  
  @objc func fromCpp(_ successCallback: RCTResponseSenderBlock) -> Void {
    successCallback([NSNull(), WrapCpp_to_RN().wrapSayHello() as Any])
    }}

b. Exporte una función de ajuste en un archivo Swift a React Native

Cree un archivo Objective C para exportar la clase Swift y su función usandoCallback

#import <React/RCTBridgeModule.h>
#import <Foundation/Foundation.h>
#import "UIKit/UIKit.h"
@interface RCT_EXTERN_MODULE(SendCpp_to_RN, NSObject)RCT_EXTERN_METHOD(fromCpp:(RCTResponseSenderBlock)successCallback)@end

C. Conecte Swift a React Native, abra el NativeModules-Bridging-Header.h archivo

#import <React/RCTBridgeModule.h>#import <React/RCTViewManager.h>#import "WrapCpp_to_RN.h"

6. Trabajando en el lado de React Native

Llame a la clase Swift y sus funciones

import React from 'react';
import {StyleSheet, Text, View, NativeModules, Button} from 'react-native';const App = () => {
  const onPress = () => {
    const {SendCpp_to_RN} = NativeModules;
    SendCpp_to_RN.fromCpp((_err, res) => console.log(res));
  };
  return (
    <View style={styles.container}>
      <Text> Practice !</Text>
      <Button title="C++ to React Native" color="#841584" onPress={onPress} />
    </View>
  );
};
const styles = StyleSheet.create({
  container: {
    flex: 1,
    justifyContent: 'center',
    alignItems: 'center',
  },
});
export default App;

Y listo, solo ejecuta la aplicación

react-native run-ios

O simplemente haga clic en el botón "ejecutar" en Xcode y vea lo que hemos hecho.

Espero que mi artículo te sea útil, gracias por tu tiempo de lectura.

如何将函数从 C++ 导出到 React Native

今天,我继续分享我在 Native Module 和 C++ 方面的经验。

由于我们将看到很多为移动平台编写的 C/C++ 库,因此我们需要将它们实现到我们的 iOS 或 React Native 应用程序中。这就是为什么我想写一篇关于如何将一个函数从 C++ 导出到 React Native 的文章,它易于理解并且为初学者节省了时间。我将从一个新的 react native 应用程序开始

1.新建一个react native app,打开你的终端运行

npx react-native init NativeModules

2. 打开 Xcode 并导航到 NativeModules/ios/NativeModule.xcworkspace

3. 在 C++ 端工作

创建一个新的 C++ 文件并命名Cpp_to_RN.cpp

当我们创建一个新的 C++ 文件时,Xcode 会Cpp_to_RN.hpp 为我们创建一个头文件

首先,打开“ Cpp_to_RN.hpp文件,并创建一个包含没有主体的函数的类。

#ifndef Cpp_to_RN_hpp
#define Cpp_to_RN_hpp#include <stdio.h>
#include <string>class Cpp_to_RN {
public:
    std::string sayHello();
};#endif /* Cpp_to_RN_hpp */

然后打开Cpp_to_RN.cpp文件,写一个简单的函数“ sayHello()

#include "Cpp_to_RN.hpp"
std::string Cpp_to_RN::sayHello(){
    return "Hello from CPP";
}

4. 处理包装 C++ 文件。

包装 C++ 文件并将它们导出到 IOS (swift) 端

一个。创建一个Objective C文件并命名Cpp_to_RN.m

重命名Cpp_to_RN.m Cpp_to_RN.mm

湾。打开WrapCpp_to_RN.mm 文件并编写将包装sayHelloC++ 文件中的函数的正文内容。

#import <Foundation/Foundation.h>
#import "WrapCpp_to_RN.h"
#import "Cpp_to_RN.hpp"@implementation WrapCpp_to_RN- (NSString *) sayHello {
  Cpp_to_RN fromCPP;
    std::string helloWorldMessage = fromCPP.sayHello();
    return [NSString
            stringWithCString:helloWorldMessage.c_str()
            encoding:NSUTF8StringEncoding];
}
@end

C。创建头文件并命名WrapCpp_to_RN.h

将函数导出wrapSayHello到 Swift 文件

#import <Foundation/Foundation.h>
@interface WrapCpp_to_RN : NSObject
- (NSString *) wrapSayHello;
@end

5. 在 iOS (Swift) 端工作

将 C++ 函数导出到 React Native

一个。创建一个 Swift 文件并命名SendCpp_to_RN.swift

注意:Xcode 会要求我们为我们创建一个NativeModules-Bridging-Header.h文件。

创建一个类SendCpp_to_RN并将其声明为NSObject

#import <Foundation/Foundation.h>
@interface WrapCpp_to_RN : NSObject
- (NSString *) wrapSayHello;
@end

编写一个函数requiresMainQueueSetup()来防止我们运行应用程序时出现警告

#import <Foundation/Foundation.h>
@interface WrapCpp_to_RN : NSObject
- (NSString *) wrapSayHello;
@end

编写一个函数来包装WrapCpp_to_RN()fromWrapCpp_to_RN.mm

import Foundation@objc(SendCpp_to_RN)
class SendCpp_to_RN : NSObject {
    
  @objc static func requiresMainQueueSetup() -> Bool {
        return false
    }
  
  @objc func fromCpp(_ successCallback: RCTResponseSenderBlock) -> Void {
    successCallback([NSNull(), WrapCpp_to_RN().wrapSayHello() as Any])
    }}

湾。将 Swift 文件中的包装函数导出到 React Native

创建一个 Objective C 文件以导出 Swift 类及其函数,使用Callback

#import <React/RCTBridgeModule.h>
#import <Foundation/Foundation.h>
#import "UIKit/UIKit.h"
@interface RCT_EXTERN_MODULE(SendCpp_to_RN, NSObject)RCT_EXTERN_METHOD(fromCpp:(RCTResponseSenderBlock)successCallback)@end

C。将 Swift 连接到 React Native,打开NativeModules-Bridging-Header.h 文件

#import <React/RCTBridgeModule.h>#import <React/RCTViewManager.h>#import "WrapCpp_to_RN.h"

6. 在 React Native 方面工作

调用 Swift 类及其函数

import React from 'react';
import {StyleSheet, Text, View, NativeModules, Button} from 'react-native';const App = () => {
  const onPress = () => {
    const {SendCpp_to_RN} = NativeModules;
    SendCpp_to_RN.fromCpp((_err, res) => console.log(res));
  };
  return (
    <View style={styles.container}>
      <Text> Practice !</Text>
      <Button title="C++ to React Native" color="#841584" onPress={onPress} />
    </View>
  );
};
const styles = StyleSheet.create({
  container: {
    flex: 1,
    justifyContent: 'center',
    alignItems: 'center',
  },
});
export default App;

我们完成了,只需运行应用程序

react-native run-ios

或者只需单击 Xcode 上的“运行”按钮,看看我们做了什么。

希望我的文章对您有所帮助,感谢您的阅读时间。

Como Exportar Uma Função De C++ Para React Native

Hoje, continuo compartilhando minha experiência com o Módulo Nativo e C++.

Como veremos muitas bibliotecas C/C++ escrevendo para plataformas móveis, precisamos implementá-las em nosso aplicativo iOS ou React Native. É por isso que quero escrever um artigo sobre como exportar uma função de C++ para React Native, que é fácil de entender e economiza tempo para iniciantes. Vou começar com um novo aplicativo nativo de reação

1. Crie um novo aplicativo nativo de reação, abra seu terminal e execute

npx react-native init NativeModules

2. Abra o Xcode e navegue até NativeModules/ios/NativeModule.xcworkspace

3. Trabalhando no lado C++

Crie um novo arquivo C++ e nomeie-oCpp_to_RN.cpp

Quando criamos um novo arquivo C++, o Xcode criará um arquivo de cabeçalho Cpp_to_RN.hpp para nós

Primeiro, abra o arquivo “ Cpp_to_RN.hpp e crie uma classe que inclua uma função sem o corpo.

#ifndef Cpp_to_RN_hpp
#define Cpp_to_RN_hpp#include <stdio.h>
#include <string>class Cpp_to_RN {
public:
    std::string sayHello();
};#endif /* Cpp_to_RN_hpp */

Em seguida, abra o Cpp_to_RN.cpparquivo e escreva uma função simples “ sayHello()

#include "Cpp_to_RN.hpp"
std::string Cpp_to_RN::sayHello(){
    return "Hello from CPP";
}

4. Trabalhando no arquivo C++ de encapsulamento.

Para encapsular os arquivos C++ e exportá-los para o lado IOS (swift)

uma. Crie um arquivo Objective C e nomeie-oCpp_to_RN.m

Renomeie o Cpp_to_RN.m para Cpp_to_RN.mm

b. Abra o WrapCpp_to_RN.mm arquivo e escreva o conteúdo do corpo que envolverá a função sayHellodo arquivo C++.

#import <Foundation/Foundation.h>
#import "WrapCpp_to_RN.h"
#import "Cpp_to_RN.hpp"@implementation WrapCpp_to_RN- (NSString *) sayHello {
  Cpp_to_RN fromCPP;
    std::string helloWorldMessage = fromCPP.sayHello();
    return [NSString
            stringWithCString:helloWorldMessage.c_str()
            encoding:NSUTF8StringEncoding];
}
@end

c. Crie um arquivo de cabeçalho e nomeie-oWrapCpp_to_RN.h

Exporte a wrapSayHellofunção para o arquivo Swift

#import <Foundation/Foundation.h>
@interface WrapCpp_to_RN : NSObject
- (NSString *) wrapSayHello;
@end

5. Trabalhando no lado iOS (Swift)

Para exportar a função C++ para React Native

uma. Crie um arquivo Swift e nomeie-oSendCpp_to_RN.swift

Observação: o Xcode nos pedirá para criar um NativeModules-Bridging-Header.harquivo para nós.

Crie uma classe SendCpp_to_RNe declare-a comoNSObject

#import <Foundation/Foundation.h>
@interface WrapCpp_to_RN : NSObject
- (NSString *) wrapSayHello;
@end

Escreva uma função requiresMainQueueSetup()para evitar avisos quando executamos o aplicativo

#import <Foundation/Foundation.h>
@interface WrapCpp_to_RN : NSObject
- (NSString *) wrapSayHello;
@end

Escreva uma função para envolver o WrapCpp_to_RN()fromWrapCpp_to_RN.mm

import Foundation@objc(SendCpp_to_RN)
class SendCpp_to_RN : NSObject {
    
  @objc static func requiresMainQueueSetup() -> Bool {
        return false
    }
  
  @objc func fromCpp(_ successCallback: RCTResponseSenderBlock) -> Void {
    successCallback([NSNull(), WrapCpp_to_RN().wrapSayHello() as Any])
    }}

b. Exporte uma função wrap no arquivo Swift para React Native

Crie um arquivo Objective C para exportar a classe Swift e sua função usandoCallback

#import <React/RCTBridgeModule.h>
#import <Foundation/Foundation.h>
#import "UIKit/UIKit.h"
@interface RCT_EXTERN_MODULE(SendCpp_to_RN, NSObject)RCT_EXTERN_METHOD(fromCpp:(RCTResponseSenderBlock)successCallback)@end

c. Conecte o Swift ao React Native, abra o NativeModules-Bridging-Header.h arquivo

#import <React/RCTBridgeModule.h>#import <React/RCTViewManager.h>#import "WrapCpp_to_RN.h"

6. Trabalhando no lado React Native

Chame a classe Swift e suas funções

import React from 'react';
import {StyleSheet, Text, View, NativeModules, Button} from 'react-native';const App = () => {
  const onPress = () => {
    const {SendCpp_to_RN} = NativeModules;
    SendCpp_to_RN.fromCpp((_err, res) => console.log(res));
  };
  return (
    <View style={styles.container}>
      <Text> Practice !</Text>
      <Button title="C++ to React Native" color="#841584" onPress={onPress} />
    </View>
  );
};
const styles = StyleSheet.create({
  container: {
    flex: 1,
    justifyContent: 'center',
    alignItems: 'center',
  },
});
export default App;

E pronto, basta executar o aplicativo

react-native run-ios

Ou apenas clique no botão “executar” no Xcode e veja o que fizemos.

Espero que meu artigo seja útil para você, obrigado pelo tempo de leitura.
