CABAsiCAnimAtion

如何在ios中运用core animation暂停和继续动画 核心代码如下 //暂停layer上面的动画 - (void)pauseLayer:(CALayer*)layer { CFTimeInterval pausedTime = [layer convertTime:CACurrentMediaTime() fromLayer:nil]; layer.speed = 0.0; layer.ti...

- (void)animationDidStop:(CAAnimation *)anim finished:(BOOL)flag { if ([xxx.layer valueForKey:@"animationPosition1"]==anim) { ........ } } 还有一个办法,你可以指定每个动画的结束方法 + (void)setAnimationDidStopSelector:(SEL)selector

frame没有关键帧,可以用动画组实现 CGRect frame = itemLayer.frame; CABasicAnimation *aniBounds = [CABasicAnimation animationWithKeyPath:@"bounds"];...

- (void)viewDidLoad { [super viewDidLoad]; int i; int n = 0; UIScrollView *newscrollview = [[UIScrollView alloc]init]; newscrollview.frame = CGRectMake(0, 0, 320, 400); [self.view addSubview:newscrollview]; newscrollview.backgr...

平移动画在应用开发中可以使用CABasicAnimation. 但通过你上面的描述,我感觉使用CAKeyFrameAnimation更适合你的需求,平移的方向可以看做是动画移动的路径,你只需要通过得到这个CGPath 就可以完成这个动画在沿着你指定的路径进行平移

- (void)animationDidStop:(CAAnimation *)anim finished:(BOOL)flag { if ([xxx.layer valueForKey:@"animationPosition1"]==anim) { ........ } }

(void)animationDidStop:(CAAnimation *)anim finished:(BOOL)flag { if ([xxx.layer valueForKey:@"animationPosition1"]==anim) { } }

CABasicAnimation *FlipHorAnimation = [CABasicAnimation animationWithKeyPath:@"transform.rotation.y"]; FlipHorAnimation.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut]; FlipHorAnimat...

旧动画直接removeAllAnimations, 然后重新创建和添加动画. 之前有某个项目内的动画是这样处理的.
