Question

I am using a tab bar controller for my app. If I’m in one of the view controllers called “results” and the ios device rotates to landscape mode, it switches for another view I created called landScape. This has been done within the method

-(void)willRotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrient‌​ation duration:(NSTimeInterval)duration
{
    [super willRotateToInterfaceOrientation:toInterfaceOrientation duration:duration];
    if (toInterfaceOrientation == UIInterfaceOrientationLandscapeRight ||
        toInterfaceOrientation == UIInterfaceOrientationLandscapeLeft)
    {
        self.view=landScape;
    } else {
        self.view=originalView;
    }
}

It works just fine whenever I am in that specific controller within the tab bar (example results view controller). However; If I go to another element in my tab bar controller and my phone is tilted in landscape mode and then I decide to go to resultsviewcontroller, it does not call upon my view landScape, instead it tries to autosize the view on its own and it looks awful. Should I call the method -(void)willRotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration within my viewDidLoad method to solve the problem? Or is this completely wrong?

Thank you in advance!

The problem is you’re only setting resultsViewController.view when it is the active view controller and detects a rotation. Try this:

- (void)setViewForInterfaceOrientation:(UIInterfaceOrientation)orientation
{
    self.view = UIInterfaceOrientationIsPortrait(orientation)
        ? originalView
        : landScape;
}

- (void)viewWillAppear
{
    [self setViewForInterfaceOrientation:[[UIDevice currentDevice] orientation];
    [super viewWillAppear];
}

-(void)willRotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrient‌​ation duration:(NSTimeInterval)duration
{
    [self setViewForInterfaceOrientation:toInterfaceOrientation];
    [super willRotateToInterfaceOrientation:toInterfaceOrientation duration:duration];
}
