GameCenter landscape orientation doesn't work on iPad

Question

Can anyone explain me what's going on? I use this method

- (BOOL)shouldAutorotateToInterfaceOrientation:( UIInterfaceOrientation)interfaceOrientation
 {     
return ( UIInterfaceOrientationIsLandscape( interfaceOrientation ) );
 }

to provide landscape orientation for the matchmakerViewController. It works perfectly on iPhone and even on iPad simulator but not on iPad device. When i run the application on iPad matchmakerViewController misteriously appear in the portrait orientation. What's wrong? How do i fix it? Thanks

Answer 1

Change your shouldAutorotateToInterfaceOrientation like

-(BOOL)shouldAutorotateToInterfaceOrientation:( UIInterfaceOrientation)interfaceOrientation
 {     
     return (interfaceOrientation == UIInterfaceOrientationLandscapeLeft || interfaceOrientation == UIInterfaceOrientationLandscapeRight);
 }

Also check your application plist file, there will be a key like Supported Interface Orientations it's type will be array and will have 4 values . Delete the portrait modes from the plist and save it . It will work. Please check this.

Answer 2

(This is most likely not your problem, but I use the following code and it works fine)

return (interfaceOrientation == UIInterfaceOrientationLandscapeLeft || 
interfaceOrientation == UIInterfaceOrientationLandscapeRight)

Additionally, make sure the parent view is set to autorotate true. shouldAutorotateToInterfaceOrientation doesn't work

Answer 3

Here is the elegant solution through Categories, extend the GKMatchMakerViewController, the same solution will work on any other game center view such as leader board views and achievement views:

.h file

#import <Foundation/Foundation.h>
#import "GameKit/GameKit.h"

@interface GKMatchmakerViewController(LandscapeOnly)



-(BOOL) shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation;

@end

.m file

#import "GKMatchmakerViewController-Landscape.h"

@implementation GKMatchmakerViewController(LandscapeOnly)


-(BOOL) shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation {

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


}

@end

Let me know if it works!!

Answer 4

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
    // Return YES for supported orientations
    return (interfaceOrientation == UIInterfaceOrientationLandscapeLeft);
}


also check parent controller maybe some controller return YES

or try 

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
    // Return YES for supported orientations
    if (interfaceOrientation==UIInterfaceOrientationPortrait)
        return (interfaceOrientation == UIInterfaceOrientationLandscapeLeft);
    else 
        return NO;
}
