Crash when using IQKeyboardManager about interfacss

[bangerang]

This also throws an exception:

 UIToolbar* numberToolbar = [[UIToolbar alloc]initWithFrame:CGRectMake(0, 0, self.view.frame.size.width, 50)];
    numberToolbar.barStyle = UIBarStyleBlackTranslucent;
    numberToolbar.items = [NSArray arrayWithObjects:
                           [[UIBarButtonItem alloc]initWithTitle:@"Cancel" style:UIBarButtonItemStyleDone target:self action:@selector(cancelNumberPad)],
                           [[UIBarButtonItem alloc]initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:nil action:nil],
                           [[UIBarButtonItem alloc]initWithTitle:@"Done" style:UIBarButtonItemStyleDone target:self action:@selector(doneWithNumberPad)],
                           nil];
    [numberToolbar sizeToFit];

    UITextField *pnoField = [self.view subviewWithElementId:@"loginDetailsPersonalNumberInputField"];
    pnoField.inputAccessoryView = numberToolbar;

Well, I would of course love it if InterfaCSS played nice with other frameworks as well. :) So I'll have to investigate what the underlying reason for the crash is.
