轻拍并轻拍不工作; iphone手势识别器

Question

我有一个表单，假设通过点击向上显示并隐藏，但点击手势无法正常工作，当我点击其标签时，表单视图会显示。

- (void)hideForm
{
    self.xButton.hidden = NO;
    self.yButton.hidden = NO;
    [self.testView addSubview:self.formLabel];
    [UIView animateWithDuration:kDefaultAnimationDuration
                     animations:^{
                         CGRect frame = self.formView.frame;
                         frame.origin.y += self.formView.frame.size.height -Height;
                         self.formView.frame = frame;

                         self.formLabel.alpha = 1.0;

                         frame = self.Form.frame;
                         frame.origin.y = Height;
                         self.Form.frame = frame;
                     }
                     completion:^(BOOL finished) {

                     }];
}

和

- (void)showForm:(UITapGestureRecognizer *)gesture
{

    self.xButton.hidden = YES;
    self.yButton.hidden = YES;

    [UIView animateWithDuration:kDefaultAnimationDuration
                     animations:^{
                         CGRect frame = self.formView.frame;
                         frame.origin.y -= self.formView.frame.size.height - Height;
                         self.formView.frame = frame;


                         self.formLabel.alpha = 0.0;

                         frame = self.Form.frame;
                         frame.origin.y = 0.0;
                         self.Form.frame = frame;
                     }
                     completion:^(BOOL finished) {

                         [self.formLabel removeFromSuperview];

                     }];
}

- (UILabel *)formLabel
{
        formLabel.userInteractionEnabled = YES;
        UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(showForm:)];
        [formLabel addGestureRecognizer:tap];
        [formLabel setBackgroundColor:[UIColor clearColor]];
}

要点击，有一个标签可以点击，但是当表单显示时，标签将消失，表单需要通过点击表单的背景图像来消失。

任何想法如何解决这个问题？
