Add a subview without waiting until the next frame.

Question

I'm trying to create a loading view that is displayed when code is being called. Right now when I call to add a subview it isn't added until the rest of the method has been run through. For example,

- (void)loadFight:(NSString*)levelName
{
    [self createLoadingView];
    sumoController = [[sumoViewController alloc] initWithNibName:@"sumoViewController" bundle:nil];
    [window insertSubview:sumoController.view belowSubview:levelController.view];
    [sumoController setUpLevel:@"school" stats:playerStats];
    [levelController.view removeFromSuperview];
    [self removeLoadingView];
    [sumoController startMatch];
}

I've found that there is no point for me to call the createLoadingView method because it isn't shown until everything has been initialized and by then i remove it.
