Close Keyboard in iOS on touch anywhere in Swift

Question

I know that to close the keyboard by touching anywhere else in Obj-C you would have to write

- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
UITouch *touch = [[event allTouches] anyObject];
if ([_answerField isFirstResponder] && [touch view] != _answerField) {
    [_answerField resignFirstResponder];
}
[super touchesBegan:touches withEvent:event];
}

But how would you do that with Swift?

Thanks

This will only close the keyboard if `_answerField`, whatever that is, is the first responder. What you really want is to call `endEditing:YES` on the view. — nhgrif, Jun 13 '14 at 01:44

Here's the translation:

override func touchesBegan(touches: NSSet!, withEvent event: UIEvent!) {
    let touch = event.allTouches().anyObject() as UITouch
    if _answerField.isFirstResponder() && touch.view != _answerField {
        _answerField.resignFirstResponder()
    }
    super.touchesBegan(touches, withEvent: event)
}

I recommend reading Apple's "The Swift Programming Language" book and looking over Apple's beta documentation involving their existing API's and how to interact with them.

Thanks. XCode gives me a suggestion to change let touch = event.allTouches().anyObject() to let touch : AnyObject! = event.allTouches().anyObject() – lagoon Jun 13 '14 at 01:44
This will only close the keyboard if `_answerField`, whatever that is, is the first responder. What you really want is to call `endEditing:YES` on the view. Otherwise, if you have multiple text fields, this code quickly become really silly. – nhgrif Jun 13 '14 at 01:45
Thanks for that nhgrif. I only have one text field for this one but when I run this code, it gives me an error on ** and says use of unresolved identifier '**' and operator is an unknown binary operator – lagoon Jun 13 '14 at 01:51
Sorry about that. Those should be `&&` instead. I also added the cast to UITouch that was causing the other warning. – David Skrundz Jun 13 '14 at 01:51

You can try as alternative assign UITapGestureRecognizer (with self.view.endEditing(true) ) to parent view
