解决方法
@H_502_9@ 所以在我按下后,我突然把两个和两个放在一起,并认为Metronome样品的工作类似于一个摆动的门,这让我有了一些其他的可能性.这是我的解决方案：
- (void)viewDidLoad {
[super viewDidLoad];
// Set the anchor point and center so the view swings from the upper right
swingView.layer.anchorPoint = CGPointMake(1.0,0.0);
swingView.center = CGPointMake(CGRectGetWidth(self.view.bounds),0.0);
// Rotate 90 degrees to hide it off screen
CGAffineTransform rotationTransform = CGAffineTransformIdentity;
rotationTransform = CGAffineTransformRotate(rotationTransform,DegreesToRadians(90));
swingView.transform = rotationTransform;
}
...
- (void)animateSwing {
CGAffineTransform swingTransform = CGAffineTransformIdentity;
swingTransform = CGAffineTransformRotate(swingTransform,DegreesToRadians(0));
[UIView beginAnimations:@"swing" context:swingView];
[UIView setAnimationDuration:0.25];
swingView.transform = swingTransform;
[UIView commitAnimations];
}
希望这也有助于其他人！
