[SOLVED] Allow portrait Only - Works in iOS6 but not iOS5

Allow portrait Only - Works in iOS6 but not iOS5

I'm building a project with a Base SDK of iOS 6.0.

In Targets > Summary I've set the Supported Device orientations' to portrait only (the other orientations are unselected).

This works great when I run the app in the 6.0 simulator, the app is locked to portrait as intended. However when I run the the 5.1 simulator, it's supporting both landscape orientations (but not upside down)!?

I want to force portrait throughout every view in the entire app (bar one view controller). Currently when testing in iOS 5.1 it allows rotation no matter what I do.

Despite being depreciated in iOS6, I've kept:

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

but that doesn't do anything.

How can I force portrait only in iOS 5.0 also?

Solution

shouldAutorotateToInterfaceOrientation should do the trick. Are you sure it is executing? Are you sure it is defined in your main view controller, not somewhere else?
