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:
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!
