How to execute code after a UIImageView animation completes--without timers!

[kjmcneish]

I found a great little extension to UIImageView that allows you to specify a block to be executed after the UIImageView animation is complete. Unlike other solutions that use a timer (bad idea). It uses CAKeyframeAnimation instead, with its animationDidStop method, which is far more reliable:

It's written in Objective-C, so you Swifters just need to add it to your project and then import it in your bridging header file:

Code: [Select]

#import "UIImageView+AnimationCompletion.h"
All the best!
