ios开发 按钮点击后翻转效果

（1）引入“QuartzCore.framework”库，头部引用。

#include<QuartzCore/QuartzCore.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：

CATransform3DMakeRotation( M_PI/2 , 0 , 1 , 0 );第一个参数是旋转的角度，有一点需要著名，就是对象回按照你设定的角度的最短距离去旋转，后面三个参数分别是xyz（-1~1之间的值）代表的一个向量值。顺时针或者逆时针旋转尚未搞定具体是什么参数来控制的，有知道的朋友提醒下，谢谢！
