Rotate one UIViewController in UITabBar application

I have uitabbar application and 开发者_运维技巧I Want to rotate just one ViewController with chart in landscape mode. It's possible to do that?

There is no easy way to have only one view in landscape mode, while the others are in landscape, nor an easy way to programmatically switch to landscape mode.

One possible approach would be using a CGAffineTransform to transform your view in your viewWillAppear (i.e., right before the view is shown):

- (void)viewWillAppear:(BOOL)animated; {
   //-- Adjust the status bar
   [UIApplication sharedApplication].statusBarOrientation = UIInterfaceOrientationLandscapeRight;
   //-- Rotate the view
   CGAffineTransform toLandscape = CGAffineTransformMakeRotation(degreesToRadian(90));
   toLandscape = CGAffineTransformTranslate(toLandscape, +90.0, +90.0 );
   [self.view setTransform:toLandscape];
}

Hope this works for you.

Only if it's modal, if it's part of the tabBarController, you need to support orientation change for all your controller
