A useful UIView category containing a set of most commonly used animations like rotation, flip, shake and others.

It is designed to be as easy to use and integrate as possible with a goal to speed up everyday development tasks. All the methods are well documented and described.

Furthermore, the category comes along with a small demo project where you can see the animations in action.

Extension contains helper methods for the following animations:

[boxView rotateToAngle:M_PI * 2.0f
              duration:1.0f
             direction:UIViewAnimationRotationDirectionLeft
           repeatCount:HUGE_VALF
           autoreverse:YES];

[boxView flipWithDuration:0.3f
                direction:UIViewAnimationFlipDirectionFromLeft
              repeatCount:2
              autoreverse:NO];

[boxView shakeVertically];

[boxView shakeHorizontally];

[boxView pulseToSize:1.1f
            duration:0.3f
              repeat:YES];

[boxView applyMotionEffects];

Can't be shown in a gif. Run on the device to see it in action.

The recommended approach for installing Animation Extensions is via the CocoaPods package manager, as it provides flexible dependency management and dead simple installation.

Install CocoaPods if not already available:

$ [sudo] gem install cocoapods
$ pod setup

Change to the directory of your Xcode project, and Create and Edit your Podfile and add Animation Extensions:

$ cd /path/to/MyProject
$ touch Podfile
$ edit Podfile
target "YOUR PROJECT" do
	platform :ios, '11.0'
	pod 'UIView+AnimationExtensions', '~> 2.0.0'
end

Install into your project:

$ pod install

Open your project in Xcode from the .xcworkspace file (not the usual project file)

$ open MyProject.xcworkspace

Please note that if your installation fails, it may be because you are installing with a version of Git lower than CocoaPods is expecting. You can get a full picture of the installation details by executing pod install --verbose.

Install Animation Extensions using one of the above methods. Then

1. If Animation Extensions are built as a dynamic framework, add:

   @import UIView+AnimationExtensions;

2. If Animation Extensions are built as a static library, add into the bridging header for your Swift project:

   #import <UIView+AnimationExtensions/UIView+AnimationExtensions.h>

UIView Animation Extensions is a category on UIView and - as with all UIKit components - it should only be accessed from the main thread.
