Trying to wrap my head around the apple design scheme. I have a UIViewController

  • 0

Trying to wrap my head around the apple design scheme. I have a UIViewController and the corresponding XIB file that has my main screen in my application. I want to have a button on this XIB that displays another “form” (this is my disconnect) in the foreground where the user selects from a myriad of choices, then it hides that “form” and goes back to the first one.

I’m completely lost here. Initially I thought I’d just add another view and set the self.view of my controller to the new view, add another IBAction and call it a day, but I can’t seem to make that work. For sake of argument, say I want to “gray out” the current form, have a modal type window that takes up roughly 60% of the screen and requires you select an option, then it hides itself and we go back to normal. What is the standard approach here?

Thanks

    Your ViewController does what’s its name indicates; controls a UIView. If you have an additional view for your form, you can just add it to the ViewController’s view:

    [self.view addSubview:yourFormUIView];

    This will add your new view to the view that is (essentially) in the the related .xib file. You might also want to check out modal view controllers istead.
