[IOS] uikit Animation

Uikit animation can be created and started in two ways:

1. Use animation Context

[Uiview beginanimations:@"Box-animate"Context: Nil];//Start to create an animation. Each animation has its string name. Here we take "Box-animate" as an example.[Uiview setanimationduration:1];//Animation running time: 1 second//Set the final status of the change hereSomebtn. backgroundcolor = [uicolor bluecolor];//The button somebtn will gradually become a blue background in one second[Uiview commitanimations];//Animation starts
 

2. Use animation Blocks

[Uiview animatewithduration:1  Delay:  0  Options: uiviewanimationoptioncurvelinear  //  Animation Effect Animations: ^ ( Void  ){  //  Define animation content Somebtn. backgroundcolor = [uicolor bluecolor]; //  Make the same animation effect as Example 1.  } Completion: ^ (Bool finished ){ //  Define the operation when the animation ends Nslog ( @"  Animation finished  "  ) ;}];
