ios按钮点击后翻转效果

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。

C代码



#include<QuartzCore/CoreAnimation.h>

（2）直接上代码，你懂的。

C代码



-(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！
