UILongPressGesture to Touches在子视图中移动

Question

我有一个UIViewController，并添加了一个UILongPressGestureRecognizer，当识别时，会在顶部添加一个涵盖UIViewController的子视图，并将印刷机的坐标传递给子视图并添加一个媒体所在的形象。

我现在需要做的是移动用户拇指所在的子视图。我已在touchesMoved中实施了UIView，但在您删除手势并按下并重新开始之前，这不会注册？

如果添加UIView而不必删除并重新开始，我怎样才能启动touchesBegan？

为什么不继续使用UILongPressGesture？

    - (IBAction)longPressGestureStateChanged:(UILongPressGestureRecognizer *)sender {
        switch (sender.state) {
            case UIGestureRecognizerStatePossible:
            case UIGestureRecognizerStateBegan: {
            /* PUT YOUR IMAGE HERE */
            break;
        }
        case UIGestureRecognizerStateChanged: {
            /* MOVE YOUR IMAGE HERE */
            self.myImageView.center = [sender locationInView:self.view /* or any of your subviews */];
            break;
        }
        case UIGestureRecognizerStateCancelled:
        case UIGestureRecognizerStateFailed:
        case UIGestureRecognizerStateEnded: {
            /* REMOVE OR PROCESS END OF THIS TOUCH GESTURE */
            break;
    }
}
