Pageboy: A Simple, Highly informative Page View Controller

Pageboy

TL;DR UIPageViewController done properly.

⭐️ Features

  •  Simplified data source management & enhanced delegation.
  •  Dynamically insert & remove pages.
  •  Infinite scrolling support.
  •  Automatic timer-based page transitioning.
  •  Support for custom animated page transitions.

📋 Requirements

Pageboy requires iOS 9 / tvOS 10; and is compatible with Swift 5.

📲 Installation

Swift Package Manager

Pageboy is compatible with Swift Package Manager and can be integrated via Xcode.

CocoaPods

Pageboy is also available through CocoaPods:

pod 'Pageboy', '~> 3.7'

Carthage

Pageboy is also available through Carthage:

github "uias/Pageboy" ~> 3.7

🚀 Usage

The Basics

Create an instance of a PageboyViewController and provide it with a PageboyViewControllerDataSource.

class PageViewController: PageboyViewController, PageboyViewControllerDataSource {

    override func viewDidLoad() {
        super.viewDidLoad()
        
    self.dataSource = self
    }
}

Implement the PageboyViewControllerDataSource functions.

func numberOfViewControllers(in pageboyViewController: PageboyViewController) -> Int {
    return viewControllers.count
}

func viewController(for pageboyViewController: PageboyViewController,
                    at index: PageboyViewController.PageIndex) -> UIViewController? {
    return viewControllers[index]
}

func defaultPage(for pageboyViewController: PageboyViewController) -> PageboyViewController.Page? {
    return nil
}

PageboyViewControllerDelegate

The delegate functions provided by a PageboyViewController are much more reliable and useful than what a raw UIPageViewController provides. You can use them to find out exactly where the current page is, and when it's moved, where it's headed.

willScrollToPageAtIndex

About to embark on a transition to a new page.

func pageboyViewController(_ pageboyViewController: PageboyViewController,
                           willScrollToPageAt index: Int,
                           direction: PageboyViewController.NavigationDirection,
                           animated: Bool)

didScrollToPosition

Scrolled to a relative position along the way transitioning to a new page.

func pageboyViewController(_ pageboyViewController: PageboyViewController,
                           didScrollTo position: CGPoint,
                           direction: PageboyViewController.NavigationDirection,
                           animated: Bool)

didScrollToPage

Successfully completed a scroll transition to a page.

func pageboyViewController(_ pageboyViewController: PageboyViewController,
                           didScrollToPageAt index: Int,
                           direction: PageboyViewController.NavigationDirection,
                           animated: Bool)

didReload

Child view controllers have been reloaded.

func pageboyViewController(_ pageboyViewController: PageboyViewController,
                           didReloadWith currentViewController: UIViewController,
                           currentPageIndex: PageIndex)

Navigation

You can navigate programmatically through a PageboyViewController using scrollToPage():

pageViewController.scrollToPage(.next, animated: true)
  • Infinite scrolling can be enabled with .isInfiniteScrollEnabled.
  • Interactive scrolling can also be controlled with .isScrollEnabled.

Insertion & Deletion

Pageboy provides the ability to insert and delete pages dynamically in the PageboyViewController.

func insertPage(at index: PageIndex, then updateBehavior: PageUpdateBehavior)
func deletePage(at index: PageIndex, then updateBehavior: PageUpdateBehavior)

This behaves similarly to the insertion of rows in UITableView, in the fact that you have to update the data source prior to calling any of the update functions.

Example:

let index = 2
viewControllers.insert(UIViewController(), at: index)
pageViewController.insertPage(at: index)

The default behavior after inserting or deleting a page is to scroll to the update location, this however can be configured by passing a PageUpdateBehavior value other than .scrollToUpdate.

⚡️ Other Extras

  • reloadData() - Reload the view controllers in the page view controller. (Reloads the data source).
  • .navigationOrientation - Whether to orientate the pages horizontally or vertically.
  • .currentViewController - The currently visible view controller if it exists.
  • .currentPosition - The exact current relative position of the page view controller.
  • .currentIndex - The index of the currently visible page.
  • .parentPageboy - Access the immediate parent PageboyViewController from any child view controller.

Animated Transitions

Pageboy also provides custom transition support for animated transitions. This can be customized via the .transition property on PageboyViewController.

pageboyViewController.transition = Transition(style: .push, duration: 1.0)

Note: By default this is set to nil, which uses the standard animation provided by UIPageViewController.

Auto Scrolling

PageboyAutoScroller is available to set up timer based automatic scrolling of the PageboyViewController:

pageboyViewController.autoScroller.enable()

Support for custom intermission duration and other scroll behaviors is also available.

10 Open Source/Commercial Control Panels For Virtual Machines (VM's) Management

Automatic creation and management of virtual machines is a topical issue for any company that provides VPS services. If you manage a large number of machines, a command line is definitely not the only tool you may need to perform various operations including client tasks, because such operations may be time-consuming.

In order to simplify routine tasks of server administrators and users, various companies develop control panels for virtual machines management, including interface-based solutions.

Don’t Miss: 20 Open Source/Commercial Control Panels to Manage Linux Servers

A control panel empowers you to perform any operation with a mouse click, whereas it would take you a good deal of time to complete the same task in the console. With a control panel, you will save your time and effort. However, it’s not all that simple.

Nowadays, VMmanager is the most popular software product for small and medium-sized businesses. VMware, in its turn, is a leading solution for large organizations. Both software products are commercial and rather expensive.

They deliver a large number of functions, however, some companies, especially, startups may need them. Besides, many of them cannot afford such an expensive product. For example, startups and companies in times of crisis may experience financial difficulties. Moreover, one can find interesting, outstanding solutions integrated with billing systems including tools for VM management.

How not to get lost among a great number of offers? We decided to help our users and wrote the following article, in which they will find answers to this question.

In this article, we will describe control panels for virtual machines management, both commercial and open-source, and help you choose the right solution to meet your personal needs.

Guide to PyTerrier: A Python Framework for Information Retrieval

Information Retrieval is one of the key tasks in many natural language processing applications. The process of searching and collecting information from databases or resources based on queries or requirements, Information Retrieval (IR). The fundamental elements of an Information Retrieval system are query and document. The query is the user’s information requirement, and the document is the resource that contains the information. An efficient IR system collects the required information accurately from the document in a compute-effective manner.

Register for AWS ML Fridays and learn how to make a career in data science.

The popular Information Retrieval frameworks are mostly written in Java, Scala, C++ and C. Though they are adaptable in many languages, end-to-end evaluation of Python-based IR models is a tedious process and needs many configuration adjustments. Further, reproducibility of the IR workflow under different environments is practically not possible with the available frameworks.

Machine Learning heavily relies on the high-level Python language. Deep learning models are built almost on one of the two Python frameworks: TensorFlow and PyTorch. Though most natural language processing applications are built on top of Python frameworks and libraries nowadays, there is no well-adaptable Python framework for the Information Retrieval tasks. Hence, here comes the need for a Python-based Information Retrieval framework that supports end-to-end experimentation with reproducible results and model comparisons.
