iphone autorotation动画

Question

是否可以关闭自动旋转的动画？ 我想让它旋转，但我只是不想要动画发生（就像一个即时开关）。

Answer 1

如果你真的需要，只需使用UIView setAnimationsEnabled ：

- (void)willRotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration
{
    [UIView setAnimationsEnabled:NO]; // disable animations temporarily
}

- (void)didRotateFromInterfaceOrientation:(UIInterfaceOrientation)fromInterfaceOrientation
{
    [UIView setAnimationsEnabled:YES]; // rotation finished, re-enable them
}

这对我有用。 当然，除非你有充分的理由这样做，否则不建议这样做。

Answer 2

只需添加以下代码即可覆盖标准旋转动画：

- (void)viewDidLoad
{
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(didRotate:)   name:UIDeviceOrientationDidChangeNotification object:nil];
}

- (void)didRotate:(NSNotification *)notification {
    orientation = [[UIDevice currentDevice] orientation];
    if(orientation == UIDeviceOrientationUnknown || orientation == UIDeviceOrientationFaceDown || orientation == UIDeviceOrientationFaceUp){
        orientation = UIDeviceOrientationPortrait;
    }
    [[UIApplication sharedApplication] setStatusBarOrientation:orientation animated:NO];
    [self positionScreenElements];
}

@Nils蒙克不幸的是，这并不正常工作，setStatusBarOrientation预计UIInterfaceOrientation不UIDeviceOrientation和铸造是不好的做法。 如果我错了，请纠正我
