ios按钮点击后翻转效果
上图先，图上是一个按钮，点击后旋转，代码是网上找到的，不过找到的时候直接复制下来不能用，稍微整理下，为和我一样水平的菜鸟观摩一下下。
?
（1）引入“QuartzCore.framework”库，头部引用。
?
?
#include<QuartzCore/CoreAnimation.h>?
（2）直接上代码，你懂的。

-(IBAction)buttonP:(id)sender{ [self buttonAnimation:sender];}- (CAAnimation *) animationRotate { CATransform3D rotationTransform = CATransform3DMakeRotation( M_PI/2 , 0 , 1 , 0 ); CABasicAnimation* animation; animation = [CABasicAnimation animationWithKeyPath:@"transform"]; animation.toValue = [NSValue valueWithCATransform3D:rotationTransform]; animation.duration = 3; animation.autoreverses = YES; animation.cumulative = YES; animation.repeatCount = 1; animation.beginTime = 0.1; animation.delegate = self; return animation;}- (void)buttonAnimation:(id) sender{ UIButton *theButton = sender; CAAnimation *myAnimationRotate = [self animationRotate]; CAAnimationGroup* m_pGroupAnimation; m_pGroupAnimation = [CAAnimationGroup animation]; m_pGroupAnimation.delegate = self; m_pGroupAnimation.removedOnCompletion = NO; m_pGroupAnimation.duration = 10; m_pGroupAnimation.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut]; m_pGroupAnimation.repeatCount = 1; m_pGroupAnimation.fillMode = kCAFillModeForwards; m_pGroupAnimation.animations = [NSArray arrayWithObjects:myAnimationRotate, nil]; [theButton.layer addAnimation:m_pGroupAnimation forKey:@"animationRotate"];} - (void)animationDidStop:(CAAnimation *)anim finished:(BOOL)flag{ //todo}?PS：
