闪光/闪烁UIView

我需要按一下按钮或任务完成时，弹出&倾斜动画到UIView。闪光/闪烁UIView

大多数应用于UIView动画的时候都添加或删除从UIView通常应用于但如何实现这一目标，以期已添加到查看。

动画可以是任何东西，只要它吸引用户的注意力（表明任务已完成）。

那么它是拉伸＆歪斜或闪光？ – 2012-08-13 05:31:33

任何动画都会执行:) – tGilani 2012-08-13 05:45:58

编辑How to scale and rotate a view in a single animation

您可能需要使用核心动画和组中添加两个动画：

CABasicAnimation *stetchAnimation = [CABasicAnimation animationWithKeyPath:@"transform.scale.x"]; 
stetchAnimation.toValue = [NSNumber numberWithDouble:(someView.frame.size.width+100)/someView.frame.size.width]; 

CABasicAnimation *skewAnimation = CABasicAnimation animationWithKeyPath:@"transform.rotation.x"]; 
stetchAnimation.toValue:[NSNumber numberWithInt:180]; 

//Add both animation at time when task is completed 

CAAnimationGroup *animationGroup = [CAAnimationGroup animation]; 
animationGroup.animations = [NSArray arrayWithObjects:stetchAnimation,skewAnimation,nil]; 
animationGroup.removedOnCompletion = YES; 
animationGroup.fillMode = kCAFillModeForwards; 
animationGroup.duration = 0.7; // increase duration if needed 

[someView.layer addAnimation:animationGroup forKey:@"animations"];

当最后一行被执行时，即动画被添加到图层，视图是否会开始动画，或者我是否还需要做其他操作。 – tGilani 2012-08-13 05:48:15

是的，它会开始动画 – 2012-08-13 06:16:50

简单的UIView动画;暂时增长的观点：

[UIView animateWithDuration:0.3 animations:^{ 
    CGRect frm = view.frame; 
    frm.size.width += 20; 
    frm.size.height += 20; 
    frm.origin.x -= 10; 
    frm.origin.y -= 10; 
    view.frame = frm; 
} completion:^{ 
    [UIView animateWithDuration:0.3 animations:^{ 
     CGRect frm = view.frame; 
     frm.size.width -= 20; 
     frm.size.height -= 20; 
     frm.origin.x += 10; 
     frm.origin.y += 10; 
     view.frame = frm; 
    }]; 
}];
