Launch iPhone App in iPad with landscape mode

Question

In the project summary, "Supported Interface Orientations" are all selected, as there is a photo gallery view in my App, which can be rotated with device. The other views are portrait only. The target devices is iPhone, and all things perform well in the iPhone. But when it runs in my iPad with landscape mode, the splash and the rootView are as following:

splash-landscape:

rootview-landscape:

What I expected look should be the same as the iPad is with portrait mode:

splash-portrait:

rootview-portrait:

The rootView is MyNavigationController, some related code is as following:

MyNavigationController.m

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

- (NSUInteger)supportedInterfaceOrientations {
  return UIInterfaceOrientationMaskPortrait;
}

- (BOOL)shouldAutorotate {
  return NO;
}

Answer 1

Please, correct your code with the following:

- (BOOL)shouldAutorotate {
   return YES;
}

- (NSUInteger)supportedInterfaceOrientations {
   return UIInterfaceOrientationMaskPortrait;
}

It may seem odd returning YES from shouldAutorotate. The fact is, if you do return NO, then supportedInterfaceOrientations will not be called at all and your project settings will rule. You could as well remove shouldAutorotate and it should work just the same.

Reference:

When the user changes the device orientation, the system calls this method on the root view controller or the topmost presented view controller that fills the window. If the view controller supports the new orientation, the window and view controller are rotated to the new orientation. This method is only called if the view controller’s shouldAutorotate method returns YES.
