Question

I have a UITextField on a UITableView and I am using a number keyboard however I want it to be dismissed when user clicks on anything but the UiTextField.

I have seen several solutions however there appears to not be one definitive answer. For example some talk about gestures and when I implement them they do not appear to work using the code below:

- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {

    [[self view] endEditing:TRUE];

}

As you can see I am trying but there is not one way that seems to be working. Can someone guide me please?

Thanks

Usually, you will want to hit-test the touch against areas which should not dismiss the keyboard; but in general the requirement is to tell the currently-in-focus control to “resign” it’s status as “firstResponder”. It might look like this:

- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
 [self.userInput resignFirstResponder];
}

However, you may also want to consider a special gesture recognizer for this, so that you are not having to over-analyze the NSSet of touches in the long run (delegate to the GestureRecognizer the task of determining the difference between an actual “dismiss pleas!” tap and a “can I scroll this?” swipe.
