iPhone SDK：resignFirstResponder无法正常工作

Question

For some reason, resignFirstResponder is not working. I am not sure why? I have tried to call it from textFieldDidEndEditing and nothing happens. A NIB is being used and each's delegate is pointing to files owner.

What needs to be done to get the keyboard to dismiss?

Thanks.

Answer 1

actually you should return NO so that the text field does not begin editing at all. If it does, the firstresponder gets set and the keyboard pops up again.

Answer 2

Don't use -textFieldDidEndEditing . That's called after the text field resigns firstResponder status, which is what you're trying to use it as a hook to make happen. Cart before horse, chicken-and-egg kind of problem.

Instead use -textFieldShouldReturn to get triggered when the return key is pressed (and remember to return YES; from that.) Also float a clear custom button behind the elements of the view and handle a "background tap" that goes through all the text fields on your view and resigns first responder on the lot of them.

Answer 3

Make sure your setting your delegates for the textfield.

myTextField.delegTe = self;

And you are using in your header:

<UITextFieldDelegate>

EDIT:

Try:

if(textField == myTextField){
    [textField resignFirstResponder];
}
