Answer 1

I had the exact same problem you had and found the solution incidentally. You probably don't need this anymore, but for the sake of others like me, here is the answer:

Swift:

override func canBecomeFirstResponder() -> Bool {
    return true
}

Objective-C:

- (BOOL)canBecomeFirstResponder {
    return true;
}

Just add this code in the view controller handling the alert. Only tested in swift.

Answer 2

Swizzle viewWillDisappear method for UIAlertController, and perform resignFirstResponder on correspodent text field or call endEditing: on controller's view

I am using for this ReactiveCocoa:

        let alert = UIAlertController(title: "", message: "", preferredStyle: .Alert)

        alert.addTextFieldWithConfigurationHandler {
           textField in
        }

        let textField = alert.textFields!.first!

        alert.rac_signalForSelector(#selector(viewWillDisappear(_:)))
             .subscribeNext {
                 _ in
                 textField.resignFirstResponder()
             }
