ios 转屏问题

IOS 6 以前的方法

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation

{

   NSLog(@"shouldAutorotateToInterfaceOrientation");

   return(toInterfaceOrientation ==UIInterfaceOrientationLandscapeLeft ||  toInterfaceOrientation ==UIInterfaceOrientationLandscapeRight);

}

IOS 6以后的方法

- (BOOL)shouldAutorotate

{

   return YES;

}

- (NSUInteger)supportedInterfaceOrientations

{

   returnUIInterfaceOrientationMaskAll;

 

}

- (void)willRotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientationduration:(NSTimeInterval)duration

{

   NSLog(@"将要旋转到 ");

   if (toInterfaceOrientation ==UIInterfaceOrientationLandscapeLeft ||toInterfaceOrientation ==UIInterfaceOrientationLandscapeRight )

    {

       _label.text = @"横屏";

    }

    else

    {

       _label.text = @"竖屏";

    }

 

}

- (void)didRotateFromInterfaceOrientation:(UIInterfaceOrientation)fromInterfaceOrientation

{

   NSLog(@"已经旋转到某个方向");

 

}
