UIImageViewAlignedSwift

Version License Platform Carthage compatible

Usage

To run the example project, clone the repo, and run pod install from the Example directory first.

Requirements

  • iOS 8.0+, tvOS 9.0+
  • Swift 5.x

Installation

CocoaPods

CocoaPods is a dependency manager for Cocoa projects. You can install it with the following command:

$ gem install cocoapods

To integrate UIImageViewAlignedSwift into your Xcode project using CocoaPods, specify it in your Podfile:

pod 'UIImageViewAlignedSwift'

Then, run the following command:

$ pod install

Carthage

Carthage is a decentralized dependency manager that builds your dependencies and provides you with binary frameworks.

You can install Carthage with Homebrew using the following command:

$ brew update
$ brew install carthage

To integrate UIImageViewAlignedSwift into your Xcode project using Carthage, specify it in your Cartfile:

github "sochalewski/UIImageViewAlignedSwift"

Run carthage update to build the framework and drag the built UIImageViewAlignedSwift.framework into your Xcode project.

What is it?

It is a subclass of UIImageView that allows you to customize the alignment of the displayed image inside the view's frame. This works even if the contentMode is set to .scaleAspectFit, .scaleAspectFill or .scaleToFill.

It is rewritten to Swift based on original UIImageViewAligned by reydanro.

Why a subclass of UIImageView, and not a standard UIView?

Because there are many cool categories built on top of UIImageView. Subclassing a standard UIView would mean losing them.

For example, AFNetworking's async UIImageView category works perfectly using this container class, and you don't have to worry about a thing.

How does it work?

When initialized, UIImageViewAligned will create a inner UIImageView which will actually hold the image displayed. The main class then just repositions this inner UIImageView to achieve your desired alignment.

At runtime, you can change the image, contentMode or alignment and the image will reposition itself correctly.

The image property of UIImageViewAligned is overwritten to forward the calls to the inner UIImageView, so you can just drag and drop into your app.
