ios - iPad ios6 中的方向问题

Question

我在 viewDidAppear 和 viewWillAppear 中检查设备的方向，并通过调用 willAnimateRotationToInterfaceOrientation 方法强制调整方向。

 - (void) viewWillAppear:(BOOL)animated
   {
     [super viewWillAppear:YES];
     _levelComplete = YES;

     [self willAnimateRotationToInterfaceOrientation:[[UIDevice currentDevice] orientation] duration:0.01];

   }

 - (void) willAnimateRotationToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration
  {
      if (toInterfaceOrientation == (UIInterfaceOrientationLandscapeLeft | UIInterfaceOrientationLandscapeRight) )
     {

     }
     else  if (toInterfaceOrientation == UIInterfaceOrientationPortrait)
     {

     }
 }

我面临的问题是 toInterfaceOrientation 对于 viewDidAppear 和 viewWillAppear 方法都保持为 0，因此程序崩溃。

可能是什么问题？

请帮忙!

试试这个

    - (void) viewDidLoad
       {
         _levelComplete = YES;

        [self adjustViewsForOrientation:self.interfaceOrientation];

       }
    -(void) adjustViewsForOrientation:(UIInterfaceOrientation)orientation
   {

      if (orientation == UIInterfaceOrientationPortrait || orientation == UIInterfaceOrientationPortraitUpsideDown)
        {

        }
        else
        {
        }
 }
