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！
