最近Tumblr輕博客無論是web端還是移動端，都非常受歡迎，簡單調(diào)研了一下，其中動畫是我感興趣的，特此寫了個仿Tumblr點贊心破碎動畫；
1.首先看下效果：
2.模仿Tumblr中的效果應(yīng)用如下：
原理：使用按鈕點擊Action增加兩個事件，通過改變背景hidden和frame，切換圖片，增加動畫效果等；
setupUI及touch Action：
<span style="font-size:14px;">- (void)setupUI { // 點擊的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> 以上所述是小編給大家介紹的iOS開發(fā)中仿Tumblr點贊心破碎動畫效果，希望對大家有所幫助，如果大家有任何疑問請給我留言，小編會及時回復(fù)大家的。在此也非常感謝大家對武林網(wǎng)網(wǎng)站的支持！
