Question

currently working on an app at work that uses a tab bar controller. The app will not rotate to landscape mode at all – all views inherit from a baseVieController, and in here I have implemented:

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

Now I know a tabBar controller will not rotate unless all its subviews support the orientation the view is trying to rotate to – my question is this: If I do not implement the – (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation method in all subviews, will it lock these subviews to portrait mode, even if I do not specify this as a desired orientation? Therefore locking the whole tabBar controller to portrait. I know similar questions have been asked before, but I couldn’t find the answer to this specific question. Thanks in advance.

Answer 1

You can rotate the view, just needs to over ride like below:
Just add the code in the view controller class where you want rotation on (here it is for “SampleClassName”)

@interface UITabBarController (rotation)
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation;
@end


@implementation UITabBarController (rotation)
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {

    if ([self.selectedViewController isKindOfClass:[UINavigationController class]])
    {
        UINavigationController *navController = (UINavigationController *) self.selectedViewController;
        if ([[navController visibleViewController] isKindOfClass:[SampleClassName class]])
            return YES;
    }
    return (interfaceOrientation == UIInterfaceOrientationPortrait);
}
@end
