Is addSubview:view needed if I create the view hierarchy in Interface Builder

Question

I have succesfully created a view hierarchy programmatically. I now want to replicate this hierarchy using Interface Builder (IB) instead.

In IB I have nested a UIView within the main Window. Do I now nolonger need the following in method applicationDidFinishLaunching:application:

[window addSubview:controller.view];
[window makeKeyAndVisible];

Notes: controller is a member of my UIApplicationDelegate subclass.

Thanks, Doug

Answer 1

No, you will not need to add it programmatically. If the view appears within the window in IB, it is automatically being added as a subview when the nib loads. In fact, you shouldn't even need to call [window makeKeyAndVisible] if your window is set up properly in IB.

No, you shouldn't need addSubView here. Make sure that the correct nib file is loaded, that is the view associated with the Window for a window based app.
