Instance Method

insertChildViewController:atIndex:

Inserts a specified child view controller into the childViewControllers array at a specified position.

Declaration

- (void)insertChildViewController:(NSViewController *)childViewController atIndex:(NSInteger)index;

Parameters

childViewController

The child view controller to add to the childViewControllers array.

index

The index in the childViewControllers array at which to insert the child view controller. This value must not be greater than the count of elements in the array.

Discussion

You should instead use the addChildViewController: method unless you want to perform work on child view controllers as you add them. In that case, override this method to perform that work.

If a child view controller has a different parent when you call this method, the child is first be removed from its existing parent by calling the child’s removeFromParentViewController method.
