演示如何编写自己的动画引擎:CHAnimation

jopen 10年前

CHAnimation 用来演示如何编写自己的动画引擎,灵感来自于 非死book 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"];
