Short version

If I write my own controller with a split view, what do I need to do to get the child view controllers to work properly?

For example: send viewWillAppear:, etc.

And back, I answered the following question:
Switching between UIViewControllers using UISegmentedControl

With the following answer:

The right way to do this is to force the controller to process the UISegmentedControladdition of controller representations in the form of subzones.

[self.view addSubview:controller.view];

It is your responsibility to send viewWillAppear:, etc.

However, tc. pointed out that this is not as trivial as it seems:

. View - UIViewController, ( -view {Will, Did} {Appear, Disappear}: and -shouldRotateToViewOritentation:).

"" , UIKit . --parentViewController ( , modal view controller). , - UIKit -viewSomethingSomething: , -viewDidDisappear: ! ( , , , , , call -viewWillAppear: .) , Apple "" .
