代碼是網上找到的,不過找到的時候直接複製下來不能用,稍微整理下,為和我一樣水平的菜鳥觀摩一下下。
(1)引入“QuartzCore.framework”庫,頭部引用。
C代碼
- #include<QuartzCore/CoreAnimation.h>
(2)直接上代碼,你懂的。
C代碼
- -(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 );第一個參數是旋轉的角度,有一點需要著名,就是對象回按照你設定的角度的最短距離去旋轉,後面三個參數分別是xyz(-1~1之間的值)代表的一個向量值。順時針或者逆時針旋轉尚未搞定具體是什麼參數來控制的,有知道的朋友提醒下,謝謝!
