deallocated controller called after dismissModalViewControllerAnimated

I have a modal view which is launched from the current view controller, as

[self presentModalViewCOntroller:modalViewController animated:TRUE];

The modal view controller dismisses itself when someone hits a button.

[self dismissModalViewControllerAnimated:TRUE];

A couple of screens later, I attempt to swap the root view within the window. I do this all the time with no trouble. But in a certain case, when switching the one view within the window, the picker delegate method is being called on the modal view controller even thought it was dismissed a while ago.

This is very strange because the modal view controller is usually deallocated when dismissModalViewController is called.

Why is a view from the modal view 开发者_JAVA百科controller being invoked? It appears that someone, probably the window still has a reference. Are you supposed to do something else in addition to dismissModalViewController?

Thanks

DismissModalViewController should be enough. It does seem like you have a problem with some reference hanging around that you don't intend. Without seeing more code, I can't point to anything specific.
