Switching view by changing delegate rootViewContoller

Question

I'm presently trying to switch view from a UIViewController to a SplitViewController. I'm currently doing this in my UIViewController:

AppDelegate *delegate = (AppDelegate *)[[UIApplication sharedApplication] delegate];

[UIView transitionWithView:delegate.window duration:0.5 options:UIViewAnimationOptionTransitionCrossDissolve animations:^{
    delegate.window.rootViewController = delegate.splitViewController;
} completion:nil];

[self.view removeFromSuperview];

Is it the right way to switch view ? If yes, I still have a problem to solve with that method. It first quickly shows the MasterView in Portrait Mode and then show the whole split view in the current orientation mode of the iPad.

I hope I'm clear enough.

Thank for you help.

I found a way to make it work from that thread :

RootViewController animation transition, initial orientation is wrong

AppDelegate *delegate =(AppDelegate *)[[UIApplication sharedApplication] delegate];
[UIView transitionWithView:self.window duration:0.5 options:UIViewAnimationOptionTransitionCrossDissolve animations:^{
    BOOL oldState = [UIView areAnimationsEnabled];
    [UIView setAnimationsEnabled:NO];
    delegate.window.rootViewController = self.splitViewController;
    [UIView setAnimationsEnabled:oldState];
 } 
 completion:nil];
