如何制作“抖动”动画
如何制作“抖动”动画
提问于 2012-10-03 22:27:52
在我的xcode项目中，我有一个UIImage。我想让它从左到右摇动一下(动画)。我写了这段代码，但是，它不能工作。
-(void)errorShake
{
[UIView beginAnimations:nil context:NULL];
[UIView setAnimationDuration:1.0];
[lockImage setTransform:CGAffineTransformMakeRotation(-5 * M_PI / 180.0)];
[lockImage setTransform:CGAffineTransformMakeRotation(-10 * M_PI / 180.0)];
[lockImage setTransform:CGAffineTransformMakeRotation(-15 * M_PI / 180.0)];
[lockImage setTransform:CGAffineTransformMakeRotation(-20 * M_PI / 180.0)];
[lockImage setTransform:CGAffineTransformMakeRotation(-15 * M_PI / 180.0)];
[lockImage setTransform:CGAffineTransformMakeRotation(-10 * M_PI / 180.0)];
[lockImage setTransform:CGAffineTransformMakeRotation(-5 * M_PI / 180.0)];
[lockImage setTransform:CGAffineTransformMakeRotation(0 * M_PI / 180.0)];
[lockImage setTransform:CGAffineTransformMakeRotation(5 * M_PI / 180.0)];
[lockImage setTransform:CGAffineTransformMakeRotation(10 * M_PI / 180.0)];
[lockImage setTransform:CGAffineTransformMakeRotation(15 * M_PI / 180.0)];
[lockImage setTransform:CGAffineTransformMakeRotation(20 * M_PI / 180.0)];
[lockImage setTransform:CGAffineTransformMakeRotation(15 * M_PI / 180.0)];
[lockImage setTransform:CGAffineTransformMakeRotation(10 * M_PI / 180.0)];
[lockImage setTransform:CGAffineTransformMakeRotation(5 * M_PI / 180.0)];
[lockImage setTransform:CGAffineTransformMakeRotation(0 * M_PI / 180.0)];
[UIView commitAnimations];
}你能告诉我，怎样才能让我的形象动摇吗？
