Question

I know this has been answered before in different ways, but I am a novice programmer and really need some contextual help. I have a basic application that has multiple view controllers (.h, .m, .xib each. EX. about.h, about.m, about.xib, options.h, options.m, etc.). I need to switch between them on the press of a button.

I had been using:

xxxViewController *titleScreen = [[xxxViewController alloc] initWithNibName:@"xxxViewController" bundle:[NSBundle mainBundle]];
    [self.view addSubview:titleScreen.view];
    [xxxViewController release];

and it worked fine to switch the views. But then I noticed that in Instruments, the overall/net bytes kept climbing, without “releasing” the view that it came from.

Am I doing something wrong? Please help… I’m desperate!

Answer 1

You aren’t switching views, you’re just just adding one on top of the other that way. If you want to navigate between different views, chances are, you want a navigation controller.
