IOS SDK: Container view with 3 UI View area how to?

I'm newbie in iOS dev. I need windows with tree views on it. I created view-base application, and added UIView controls in master view. Also i added 3 View controllers for that views with view definition in separated xib files. How to link views from separated xib files with view areas on master view? Should i manually create controller insta开发者_C百科nces and load controller's view into view areas? Or maybe is possible to create them in IB? Thank you.

You should be able to just drag the instances of the three controllers into the nib file of the master view, and resize them in order to create the desired layout. However, make sure that the properties on the subviews are correct or they could overlap. In the library window of IB, go to the classes tab, and drag the classes you want (View Controllers) to the nib.

I prefer that method over manually adding them through code, as it allows much better functionality with resizing such as from rotation.
