preferredInterfaceOrientationForPresentation必须返回支持的接口方向 [英] preferredInterfaceOrientationForPresentation must return a supported interface orientation

问题描述

此错误没有意义，因为首选方向 UIInterfaceOrientationLandscapeRight 由支持的方向返回

  // iOS6 
 
  - （BOOL）shouldAutorotate 
 {
 return NO; 
} 
 
  - （NSUInteger）supportedInterfaceOrientations 
 {
 return（UIInterfaceOrientationLandscapeRight | UIInterfaceOrientationLandscapeLeft）; 
} 
 
  - （UIInterfaceOrientation）preferredInterfaceOrientationForPresentation 
 {
 return UIInterfaceOrientationLandscapeRight; 
} 
  

错误：

< >

由于未捕获的异常而终止应用程序
'UIApplicationInvalidInterfaceOrientation'，原因：
'preferredInterfaceOrientationForPresentation必须返回支持的
接口方向！'

- （BOOL）shouldAutorotate
{
return NO;
}

- （NSUInteger）supportedInterfaceOrientations
{
return UIInterfaceOrientationMaskLandscape;
}

- （UIInterfaceOrientation）preferredInterfaceOrientationForPresentation
{
return UIInterfaceOrientationLandscapeRight;
}


此外，请确保您的 Info.plist 您为应用设置了正确的方向，因为您从 supportedInterfaceOrientations 返回的内容与 Info.plist ，如果它找不到一个通用的，那么你会得到这个错误。

This error doesn't make sense, as the preferred orientation UIInterfaceOrientationLandscapeRight is returned by the supported orientation

//iOS6

-(BOOL)shouldAutorotate
{
    return NO;
}

-(NSUInteger)supportedInterfaceOrientations
{
    return (UIInterfaceOrientationLandscapeRight | UIInterfaceOrientationLandscapeLeft);
}

- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
    return UIInterfaceOrientationLandscapeRight;
}

Error :

Terminating app due to uncaught exception 'UIApplicationInvalidInterfaceOrientation', reason: 'preferredInterfaceOrientationForPresentation must return a supported interface orientation!'

解决方案

Your code should look like this:

-(BOOL)shouldAutorotate
{
    return NO;
}

-(NSUInteger)supportedInterfaceOrientations
{
    return UIInterfaceOrientationMaskLandscape;
}

- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
    return UIInterfaceOrientationLandscapeRight;
}

Also, make sure in your Info.plist you have set the correct orientations for you app because what you return from supportedInterfaceOrientations is intersected with the Info.plist and if it can't find a common one then you'll get that error.
