iPad 1 showing portrait mode instead of Landscape

Question

I have an application on AppStore that has portrait Mode on iPhone and on iPad it works on landscape. However i am getting reports that it shows portrait on iPad 1 thus destroyed overall View.

Why is iPad 1 specifically showing Portrait mode? The version of iPad is 5.1.1

Answer 1

In ios 6, the methods for supporting interface orientation has been changed. For supporting both interface orientation in both version, we need to check the os version and write code acoordingly.

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

Support for new versions

- (NSUInteger)supportedInterfaceOrientations {

}

- (BOOL)shouldAutorotate {
   }

In my View Controller i have the following:

- (NSUInteger)supportedInterfaceOrientations {

}

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation {

}

- (BOOL)shouldAutorotate {

} 

Answer 2

Go and make sure ALL view controllers return the correct orientation modes they support. I've seen such behaviour in iOS 5 and if I recall correctly that was the reason.

Answer 3

I had a very similar from and I resolved it by changing the following code in AppDelegate.m-> applicationDidFinishLaunching:

 [self.window addSubview:self.viewController];

to

 [self.window setRootViewController:self.viewController];
