-[UITextField isFirstResponder] returns false even

问题:

In my view controller's -viewDidLoad method, I call [myTextField becomeFirstResponder]; This works like a charm, opens the keyboard and myTextField gets focus.

I have a button with a target action (the action is in the same controller) that checks [myTextField isFirstReponder] - but it always returns false (er, NO in Cocoa terms ;)).

Is that not the right way to find out if myTextField has the keyboard up for input?

What about checking the value of the editing property, ie [myTextField isEditing]?

I think your button takes over first responder status when you tap it.
