button 翻转

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
 }
