加載subView時，在超級視圖上禁用用戶交互

Question

我正在創建自定義下拉菜單，並且其功能如我所願，當我單擊select Button時它會彈出，但是當subView在按鈕上彈出時，我想禁用我的超級視圖上的所有用戶交互，即我被困在那里。

當我將菜單作為子視圖添加到超級視圖時，我試圖禁用它，但是它禁用了包括我的子視圖在內的所有觸摸事件。

所以任何人都可以幫助我。

這是我的實現

- (void) showPopUpWithTitle:(NSString *)popupTitle withOption:(NSArray *)arrOptions xy:(CGPoint)point size:(CGSize)size
{    
    dropDownObject = [[DropDownMenu alloc] initWithTitle:popupTitle options:arrOptions xy:point size:size];
    dropDownObject.delegate = self;

    [dropDownObject showInView:self.view animated:YES];
    [dropDownObject SetBackGroundDropDwon_R:0.0 G:110 B:185.0 alpha:0.60];

}

在這里dropDownObject給我返回了一個自定義tableView，它位於要在屏幕中央彈出的框架內，而與iPhone型號無關

將這個對象添加到另一個類dropDownMenu.m中定義的當前視圖中的方法中的showInView

在這里執行

- (void)showInView:(UIView *)aView animated:(BOOL)animated
{
    [aView addSubview:self];
    if (animated)
    {
        [self fadeIn];
    }
}

我還實現了視圖動畫fadeIn和fadeOut

- (void)fadeIn
{
    self.transform = CGAffineTransformMakeScale(0.5, 0.5);
    self.alpha = 0;
    [UIView animateWithDuration:.35 animations:^{
        self.alpha = 1;
        self.transform = CGAffineTransformMakeScale(1, 1);
    }];

}
- (void)fadeOut
{
    [UIView animateWithDuration:.35 animations:^{
    self.transform = CGAffineTransformMakeScale(0.5, 0.5);
    self.alpha = 0.0;
  } completion:^(BOOL finished) {
        if (finished) 
        {
            [self removeFromSuperview];
        }
    }];
}

將輕擊手勢添加到要添加下拉視圖的視圖中

   tapgesture = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(rmovetheoverlay:)];
   tapgesture_.delegate=self;
   tapgesture_.enabled=YES;
   [<viewwhereaddeddropdown> addGestureRecognizer:mTapGestureRecognizer_];

   - (void)rmovetheoverlay:(UITapGestureRecognizer *) gestureRecognizer{


    }
  - (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldReceiveTouch:(UITouch *)touch {
        DLog(@"touch view %@",[touch.view superview]);
        DLog(@"touch view %@",touch.view);
        if (([touch.view isKindOfClass:[UISearchBar class]] && touch.view==mSearchBar_)||[[touch.view superview] isKindOfClass:[UITableViewCell class]]) {
            // prevent recognizing touches on the dropdowntable
            return NO;
        }

        return YES;
    }
