iOS 学习笔记－view 常用动画的设置

iOS常用动画的封装。如下：
（1） .h 文件

#import 
@interface UIView (Animation)
@property(nonatomic,copy)void(^completeBlock)();
- (void) shakeAnimation;
- (void) springingAnimation;
- (void) trans180DegreeAnimation;
- (void) throwFrom:(CGPoint)start to:(CGPoint)end height:(CGFloat)height
          duration:(CGFloat)duration completedBlock:(void(^)())completedBlock;
- (void) praiseAnimation;
@end

（2）.m文件

#import "UIView+Animation.h"
#import 
#import 
@implementation UIView (Animation)
static const void *UtilityKey = &UtilityKey;

-(void)setCompleteBlock:(void (^)())completeBlock
{
    objc_setAssociatedObject(self, &UtilityKey, completeBlock, OBJC_ASSOCIATION_COPY_NONATOMIC);
}
-(void(^)())completeBlock
{
    return objc_getAssociatedObject(self, UtilityKey);
}

- (void) shakeAnimation {
    
    CALayer* layer = [self layer];
    CGPoint position = [layer position];
    CGPoint y = CGPointMake(position.x - 8.0f, position.y);
    CGPoint x = CGPointMake(position.x + 8.0f, position.y);
    CABasicAnimation* animation = [CABasicAnimation animationWithKeyPath:@"position"];
    [animation setTimingFunction:[CAMediaTimingFunction
                                  functionWithName:kCAMediaTimingFunctionEaseInEaseOut]];
    [animation setFromValue:[NSValue valueWithCGPoint:x]];
    [animation setToValue:[NSValue valueWithCGPoint:y]];
