iphone自转动画 [英] iphone autorotation animation

问题描述

是否有可能关闭动画的自转？我希望它旋转，但我只是不想发生的动画（如即时开关）。

Is it possible to turn off the animation for the autorotation? I want it to rotate, but I just dont want the animation to occur (like an instant switch).

推荐答案

只需添加以下code覆盖标准的旋转动画：

Just add the following code to overwrite the standard rotation animation:

- (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];
}
