Crash when hitting backspace

Hi guys,

I'm having a weird crash, when hitting backspace and having at least one token view.

Here's the crash.

*** Terminating app due to uncaught exception 'UIViewControllerHierarchyInconsistency', reason: 'child view controller:<UICompatibilityInputViewController: 0x7f9241d61490> should have parent view controller:<ContactsSelectionViewController: 0x7f9241cbbc80> but requested parent is:<UIInputWindowController: 0x7f924201ac00>'

Basically it's triggered at [self becomeFirstResponder]; in

- (void)setSelected:(BOOL)selected animated:(BOOL)animated
{
    if (_selected == selected) {
        return;
    }
    _selected = selected;

    if (selected) {
        [self becomeFirstResponder];
    }
    CGFloat selectedAlpha = (_selected ? 1.0 : 0.0);
    if (animated) {
        if (_selected) {
            self.selectedBackgroundView.alpha = 0.0;
            self.selectedBackgroundView.hidden = NO;
            self.selectedLabel.alpha = 0.0;
            self.selectedLabel.hidden = NO;
        }
        [UIView animateWithDuration:0.25 animations:^{
            self.selectedBackgroundView.alpha = selectedAlpha;
            self.selectedLabel.alpha = selectedAlpha;
        } completion:^(BOOL finished) {
            if (!_selected) {
                self.selectedBackgroundView.hidden = YES;
                self.selectedLabel.hidden = YES;
            }
        }];
    } else {
        self.selectedBackgroundView.hidden = !_selected;
        self.selectedLabel.hidden = !_selected;
    }
}

Any ideas? thanks !
