How to force portrait orientation?

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];

Answer 3

Use Following approach : In your app delegate .h

@interface PlayWithWSWithLibAppDelegate : NSObject <UIApplicationDelegate, UITabBarControllerDelegate> {

       BOOL flagOrientationAll;
}

@property (assign) BOOL flagOrientationAll;

Add following method in your app delegate .m file

- (NSUInteger)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window{
    //NSLog(@"PlayWithWSWithLibAppDelegate -- supportedInterfaceOrientationsForWindow");
    if(flagOrientationAll == YES){
        return UIInterfaceOrientationMaskPortrait;
    } else {
        return UIInterfaceOrientationMaskAll;
    }
}

Implement following way in your view which you want to rotate in both portrait and landscape both for iPhone device

-(void)viewWillAppear:(BOOL)animated
{
    self.tabBarController.delegate = self;

    PlayWithWSWithLibAppDelegate *delegate = (PlayWithWSWithLibAppDelegate *) [[UIApplication sharedApplication] delegate];
    delegate.flagOrientationAll = YES;
 }
}

-(void)viewWillDisappear:(BOOL)animated
{
    //NSLog(@"viewWillDisappear -- Start");
     PlayWithWSWithLibAppDelegate *delegate = (PlayWithWSWithLibAppDelegate *)[[UIApplication sharedApplication] delegate];
        delegate.flagOrientationAll = NO;
}

Here is my thread some what similar to your problem : iOS 7 Interface Orientation

Answer 4

#import <objc/message.h>

objc_msgSend([UIDevice currentDevice], @selector(setOrientation:), UIInterfaceOrientationLandscapeRight);//here you may change your desired Orientation
