iphone - Is this a UIKit bug? -

I'm not sure whether this bug actually comes from my app or is actually a UIKit bug. Maybe someone can explain here.

There is a tableview, each cell provides a disclosure button with a "setting" screen which is a model view. The modal view can be closed using the "Close" button.

There is a UITextview in the model view.

Now the bug comes here: the user holds a key that provides the same letter (example: A -> AAA A ...). When the user holds that key, the letters are found and the blue color is first selected. If the user keeps this button and simultaneously clicks on the "off" button the modal view disappears and the table view is visible. The keyboard goes away, but the {a ä à} menu for one second is still visible then the app crashes.

This can only be done again on the device, because you can not press two buttons simultaneously.

Here is a stack trace
