iphone - 有没有办法从 shouldAutorotateToInterfaceOrientation 跳过旋转动画？

Question

我想允许方向根据对 View Controller 的 shouldAutorotateToInterfaceOrientation 调用进行旋转。但是，我希望它立即执行此操作并跳过旋转动画(导致整个 View 旋转时角落显示黑色旋转动画的动画。

有谁知道是否有办法指定您希望它立即发生(没有动画)？

为了执行您想要的操作，您必须手动旋转(并调整大小) View 。没有任何属性可以让您轻松更改以轻松执行您想要的操作。下面是注册设备旋转事件的代码。

 - (void)viewDidLoad {
 [[UIDevice currentDevice] beginGeneratingDeviceOrientationNotifications];
 [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(orientationChanged:)
             name:UIDeviceOrientationDidChangeNotification object:nil]; 
//Whenever the device orientation changes, orientationChanged will be called

}


- (void)orientationChanged:(NSNotification *)notification
{
UIDeviceOrientation deviceOrientation = [UIDevice currentDevice].orientation;
//Based upon which orientation the device is in, update your View rotations.
//A simple view.transform = CGAffineTransformMakeRotation(whatever); will work well.
}

我认为您应该完全删除 shouldAutoRotateToInterfaceOrientation: 函数。当 View 卸载时，您还应该调用 [[UIDevice currentDevice] endGenerateDeviceOrientationNotifications];。
