我在 iOS6 中遇到自动旋转和方向问题。他们不像以前在 iOS5 中那样工作。这是示例代码。

implementation mainProgram
// view controller is defined in landscape mode (.xib file)
// The preferredInterfaceOrientationForPresentation and supportedInterfaceOrientations have not been defined because they give me problems with getting the orientation right of other calling classes

-(IBAction)somButtonPressed:(id)sender{
      [self presentViewController:inputText animated:NO completion:nil];
 }
 @end

/////////////////////////////////////////////////////////
// This has has several  UITextField 
// The view of this controller is defined as landscape in .xib
implementation inputText

- (void)viewDidLoad
{
    [super viewDidLoad];

}

- (BOOL)shouldAutorotate {
    return YES;
}

#if 0  // Disabled
- (NSUInteger)supportedInterfaceOrientations {
    return UIInterfaceOrientationLandscapeRight;
}
#endif

#if 1  // Enabled
- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation {
    return UIInterfaceOrientationLandscapeRight;
}
#endif
@end

问题/观察： 1. 如果在 inputText 中启用了supportedInterfaceOrientations，返回值为UIInterfaceOrientationLandscapeRight，程序将失败，说preferredInterfaceOrientationForPresentation 试图设置为无效的方向，即使与supportedInterfaceOrientations 完全相同

  1. 当我尝试在 inputText 的 UITextField 之一上输入文本时，键盘以纵向模式出现，而不是 LandscapeRight。inputText 控制器的视图在 LandscapeRight 方向上很好。

在我看来，它们都是 ios6 中的错误。有没有其他人遇到过这些问题？
