我通过使用循环动态创建的3次。 在于ⅰ要求旋转动画的方法如下
- (void)runRightSpinAnimationOnView:(UIView*)view duration:(CGFloat)duration rotations: (CGFloat)rotations repeat:(float)repeat;
{
CABasicAnimation* rotationAnimation;
rotationAnimation = [CABasicAnimation animationWithKeyPath:@"transform.rotation"];
rotationAnimation.fromValue = [NSNumber numberWithFloat:0];
rotationAnimation.toValue = [NSNumber numberWithFloat:((360*M_PI)/180)];
//rotationAnimation.toValue = [NSNumber numberWithFloat: M_PI * 2.0 /* full rotation*/ * rotations * duration ];
rotationAnimation.duration = duration;
//rotationAnimation.cumulative = YES;
rotationAnimation.repeatCount = repeat;
[view.layer addAnimation:rotationAnimation forKey:@"rotationAnimation"];
}
如何停止在触摸旋转动画开始的看法?......我想下面的编码在触摸开始的方法,但它没有工作
-(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
{
UITouch *touch = [touches anyObject];
int viewTag=[touch view].tag;
UIView *myView =(UIView *)[self.view viewWithTag:viewTag];
[myView.layer removeAllAnimations];
}
请帮我...
