I have a table view in a modal form sheet (iPad), and one of the cells contains a UITextField. My view controller holds a reference to the text field and is also its delegate.
When the text field hits Return, I tell it to -resignFirstResponder inside of -textFieldShouldReturn:. In another case, I want to force it to end editing, so I tell the whole table view to -endEditing:YES. Afterwards I release my local reference to the text field, and reload the row to replace it with something else.
The keyboard won't go away in either case. I don't know what's wrong, and I'm not sure how to debug further. I've never had a sticky keyboard problem with any other text editing I've done-- the firstResponder resignation has always behaved as expected.
Any thoughts? Thanks.
Implement -disablesAutomaticKeyboardDismissal and return NO. It does work on iOS 6, but you have to implement it in the right controller. If you have a modal form sheet navigation controller with a child controller that has text fields, it's the navigation controller that needs the method implementation, not the child.
