一行代码实现UIView的爆炸效果，对CAAnimationDelegate无覆盖
//UIView粉碎动画的开始和结束的协议
@protocol TXExplodeAnimDelegate <NSObject>
- (void)txExplodeAnimDidStart;
- (void)txExplodeAnimDidEnd;
@end
@interface UIView (YDExplode)
/**
TXExplodeAnimDelegate
*/
@property (weak, nonatomic) id<TXExplodeAnimDelegate> txExDelegate;
/**
图片粉碎效果
@param partNum partNum块
*/
- (void)explodeWithPartsNum:(NSInteger)partNum;
@end
