iOS开发中仿Tumblr点赞心破碎动画效果

最近Tumblr轻博客无论是web端还是移动端，都非常受欢迎，简单调研了一下，其中动画是我感兴趣的，特此写了个仿Tumblr点赞心破碎动画；

1.首先看下效果：

2.模仿Tumblr中的效果应用如下：

原理：使用按钮点击Action增加两个事件，通过改变背景hidden和frame，切换图片，增加动画效果等；

setupUI及touch Action：

<span style="font-size:14px;">- (void)setupUI 
{ 
  // 点击的btn 
  UIButton *praiseBtn = [UIButton buttonWithType:UIButtonTypeCustom]; 
  praiseBtn.frame = CGRectMake(100, 200, KKPraiseBtnWH, KKPraiseBtnWH); 
  [praiseBtn setImage:[UIImage imageNamed:@"icon_like"] forState:UIControlStateNormal]; 
  [praiseBtn setImage:[UIImage imageNamed:@"icon_likeon"] forState:UIControlStateSelected]; 
  [self.view addSubview:praiseBtn]; 
  [praiseBtn addTarget:self action:@selector(clickTheBtn:) forControlEvents:UIControlEventTouchUpInside]; 
  _praiseBtn = praiseBtn; 
  // 放大后的btn 
  _coverBtn = [UIButton buttonWithType:UIButtonTypeCustom]; 
  _coverBtn.frame = praiseBtn.frame; 
  _coverBtn.alpha = 0; 
  [_coverBtn setImage:[UIImage imageNamed:@"big"] forState:UIControlStateSelected]; 
  [_coverBtn setImage:[UIImage imageNamed:@"big"] forState:UIControlStateNormal]; 
  [self.view insertSubview:_coverBtn belowSubview:praiseBtn]; 
  _cancelPraiseImg = [[UIImageView alloc]initWithFrame:CGRectMake(80, 150, KKPraiseBtnWH*2, KKPraiseBtnWH*2*KKToBrokenHeartWH)]; 
  _cancelPraiseImg.hidden = YES; 
  _cancelPraiseImg.centerX = _praiseBtn.centerX; 
  [self.view addSubview:_cancelPraiseImg]; 
} 
-(void)clickTheBtn:(UIButton *)btn 
{ 
  [self playAnimation]; 
  btn.userInteractionEnabled = NO; 
  btn.selected = !btn.selected; 
} 
-(void)playAnimation{ 
  if (!_praiseBtn.selected) { 
    _coverBtn.alpha = 1; 
    [UIView animateWithDuration:1.0f animations:^{ 
      _coverBtn.frame = CGRectMake(80, 100, KKPraiseBtnWH*2, KKPraiseBtnWH*2); 
      CAKeyframeAnimation *anima = [CAKeyframeAnimation animationWithKeyPath:@"transform.rotation"]; 
      NSValue *value1 = [NSNumber numberWithFloat:-M_PI/180*5]; 
      NSValue *value2 = [NSNumber numberWithFloat:M_PI/180*5]; 
      NSValue *value3 = [NSNumber numberWithFloat:-M_PI/180*5]; 
      anima.values = @[value1,value2,value3]; 
      anima.repeatCount = MAXFLOAT; 
      [_coverBtn.layer addAnimation:anima forKey:nil]; 
      _coverBtn.alpha = 0; 
      _coverBtn.centerX = _praiseBtn.centerX; 
    } completion:^(BOOL finished) { 
      _coverBtn.frame = _praiseBtn.frame; 
      _praiseBtn.userInteractionEnabled = YES; 
    }]; 
  } else { 
    _cancelPraiseImg.hidden = NO; 
    NSArray *imgArr = [NSArray arrayWithObjects:[UIImage imageNamed:@"icon_like_broken1"],[UIImage imageNamed:@"icon_like_broken2"],[UIImage imageNamed:@"icon_like_broken3"],[UIImage imageNamed:@"icon_like_broken4"], nil nil]; 
    _cancelPraiseImg.animationImages = imgArr; 
    _cancelPraiseImg.animationDuration = KKBorkenTime; 
    _cancelPraiseImg.animationRepeatCount = 1; 
    [_cancelPraiseImg startAnimating]; 
    [UIView animateWithDuration:KKBorkenTime animations:^{ 
      _cancelPraiseImg.frame = CGRectMake(80, 200, KKPraiseBtnWH*2, KKPraiseBtnWH*2*KKToBrokenHeartWH); 
      _cancelPraiseImg.alpha = 0; 
    }completion:^(BOOL finished) { 
      _cancelPraiseImg.frame = CGRectMake(80, 150, KKPraiseBtnWH*2, KKPraiseBtnWH*2*KKToBrokenHeartWH); 
      _cancelPraiseImg.alpha = 1; 
      _praiseBtn.userInteractionEnabled = YES; 
    }]; 
  } 
}</span>
