How to force portrait orientation? [closed]

Question

How to force portrait orientation in iOS 7 if my application is initially supported for both orientations?

Answer 1

For the entire app, open the project file, go to the General tab, change the settings:

Or directly on the Info.plist file:

If you only want it on a specific view controller, override supportedInterfaceOrientations:

- (NSUInteger)supportedInterfaceOrientations
{
    return UIInterfaceOrientationMaskPortrait;
}

You can read more about the second method at the official UIViewController documentation. Maybe, you'll find a more suitable way for your specific problem.

Answer 2

UIViewController *c = [[UIViewController alloc]init];
[self presentViewController:c animated:NO completion:nil];
[self dismissViewControllerAnimated:NO completion:nil];
