仅支持iOS 6的一个视图的不同方向 [英] Support different orientation for only one view iOS 6

问题描述

我想在我的应用程序中仅旋转我的一个视图，无论是横向左侧还是横向右侧。我的所有其他视图都处于纵向模式，我已将我的应用程序设置为仅支持纵向模式。在iOS 6中改变方向，我不知道如何做到这一点。我试过下面发布的以下内容。谁能告诉我我做错了什么？谢谢！

I want to rotate ONLY one of my views within my app to either landscape left or landscape right. All my other views are in portrait mode and I have set my app to support only portrait mode. With orientation being changed in iOS 6, I am not sure how to do this. I have tried the following posted below. Can anyone tell me what I am doing wrong? Thanks!

-(BOOL)shouldAutorotate {
return YES;
}

-(NSUInteger)supportedInterfaceOrientations {
return UIInterfaceOrientationMaskLandscapeLeft | UIInterfaceOrientationMaskLandscapeRight;
}

-(BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{

return UIInterfaceOrientationMaskLandscapeRight | UIInterfaceOrientationMaskLandscapeLeft;
} 

我也试过：

-(BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
[[UIDevice currentDevice] beginGeneratingDeviceOrientationNotifications];
[[NSNotificationCenter defaultCenter] addObserver:self
                                         selector:@selector(didRotate:)
                                            name:UIDeviceOrientationDidChangeNotification
                                           object:nil];
return YES;//UIInterfaceOrientationMaskLandscapeRight | UIInterfaceOrientationMaskLandscapeLeft;
} 


 -(void)didRotate:(NSNotification *)notification {
 UIDeviceOrientation orientation = [[notification object] orientation];

if (orientation == UIDeviceOrientationLandscapeLeft) {
    [theImage setTransform:CGAffineTransformMakeRotation(M_PI / -2.0)];
    [self.view setTransform:CGAffineTransformMakeRotation(M_PI / 2.0)];
} else if (orientation == UIDeviceOrientationLandscapeRight) {
    [theImage setTransform:CGAffineTransformMakeRotation(M_PI / -2.0)];
    [self.view setTransform:CGAffineTransformMakeRotation(M_PI / -2.0)];
} else if (orientation == UIDeviceOrientationPortraitUpsideDown) {
    [theImage setTransform:CGAffineTransformMakeRotation(M_PI / -2.0)];
    [self.view setTransform:CGAffineTransformMakeRotation(M_PI / -2.0)];
} else if (orientation == UIDeviceOrientationPortrait) {
    [theImage setTransform:CGAffineTransformMakeRotation(M_PI / 2.0)];
    [self.view setTransform:CGAffineTransformMakeRotation(M_PI / 2.0)];
}
}

推荐答案

这为我工作如何强制UIViewController到肖像iOS 6中的方向

从UINavigationController创建一个新类别，覆盖旋转方法：

Create a new category from UINavigationController overriding the rotating methods:

-(BOOL)shouldAutorotate
{
    return [self.topViewController shouldAutorotate];
}

-(NSUInteger)supportedInterfaceOrientations
{
    return [self.topViewController supportedInterfaceOrientations];
}

- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
    return [self.topViewController preferredInterfaceOrientationForPresentation];
}

@end 

问候！
