将我的视图控制器的纵向旋转为横向和纵向模式
通常，我的应用程序以纵向模式显示除报告视图之外的所有视图。仅当我处于设置视图并将设备旋转为横向模式时，才会显示报告视图。现在，当我再次将设备旋转到纵向模式时，报告视图将关闭并显示设置视图。
In report view
> shouldAutorotateToInterfaceOrientation
return ((interfaceOrientation == UIInterfaceOrientationLandscapeRight)||( interfaceOrientation == UIInterfaceOrientationLandscapeLeft));
Here at settings view
shouldAutorotateToInterfaceOrientation
if((interfaceOrientation == UIInterfaceOrientationLandscapeRight)||( interfaceOrientation == UIInterfaceOrientationLandscapeLeft))
{
Report *report = [[Report alloc]initWithNibName:@"Report" bundle:[NSBundle mainBundle]];
[self.navigationController pushViewController:report animated:YES];
[report release];
}
return YES;
}
Normally my application shows all views in portrait mode except report view. Report view shows only when I am on settings view and I rotate my device to landscape mode. Now when I rotate my device to portrait mode again, report view is dismissed and settings view is displayed.

不要在 shouldRotate... 中创建视图控制器，而是在
willRotateToInterfaceOrientation:duration:中创建视图控制器，这是您应该响应旋转的地方。在您的shouldAutorotateToInterfaceOrientation:中，当您希望能够旋转到该方向时，只需返回 YES - 在您的情况下，看起来您想要旋转到所有方向，或除 PortraitUpsideDown 之外的所有方向。在
willRotateToInterfaceOrientation:duration:中，您可以根据需要推送或弹出视图控制器。Don't create your viewcontroller in shouldRotate..., but in
willRotateToInterfaceOrientation:duration:, which is where you're supposed to respond to a rotation. In yourshouldAutorotateToInterfaceOrientation:, just return YES when you want to be able to rotate to that orientation- in your case, it looks like you want to either all orientations, or all orientations except PortraitUpsideDown.In your
willRotateToInterfaceOrientation:duration:, you can push your viewcontroller or pop it as needed.
