I have several UITextField objects on a view. When I press on them, I get a keyboard and the UIKeyboardWillShowNotification event as well. When I push a new view controller on to the stack while one of the text fields is the first responder, the keyboard animates away (as I expected). When I then press the back button, however, they text field becomes the first responder, but the keyboard doesn’t come back up. When I click on a different text field in the same view, again, the keyboard fails to come up. It would be fine if the keyboard wasn’t up when I reentered the view, but I’m not sure what would make it fail to come up when I click on another text field. Why does this happen, and how can I fix it?

Side note, when I resign first responder before leaving the screen, everything works fine.

    I have figured it out, and to the best of my understanding this IS a bug with Apple’s code. I have a property on one of the parent views of the UITextField that is named firstResponder. There doesn’t appear to be any reason why I shouldn’t use this name but clearly Apple has already used it somewhere in their code, and when I create a property with this name, it causes the first responder code in the framework to seriously bug out. The solution is to name my property something else.

    The only reason resigning first responder was making things work was that I was also setting the firstResponder property to nil.
