演示如何编写自己的动画引擎:CHAnimation

分享到:

CHAnimation 用来演示如何编写自己的动画引擎,灵感来自于 Facebook Pop,只需 600 行的 Objective-C 代码。

#import "CHAnimation.h"
CHAnimation *animation = [CHAnimation new];
animation.duration = 0.4;
animation.writeBlock = ^(id obj, id value) {
button.center = [value CGPointValue];
};
animation.fromValue = [NSValue valueWithCGPoint:CGPointMake(70, 70)];
animation.toValue = [NSValue valueWithCGPoint:CGPointMake(170, 170)];
[button ch_addAnimation:animation forKey:@"animation"];
