如何禁用滚动视图子视图的点击手势？

Question

我创建了一个用于注册的滚动视图。我还使用 tableview 进行下拉（男性/女性）并在滚动视图上点击 Gesture 以隐藏所有输入视图，因为 touchesBegan 方法不会调用。每当我点击表格视图单元格时，它不会调用 didselect 方法，而是认为是点击滚动视图。

UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(dismissKeyboard)];
tap.numberOfTapsRequired=1;
[_scrollview_out addGestureRecognizer:tap];

方法：-

-(void)dismissKeyboard
{
    [_txt_name resignFirstResponder];
    [_txt_mname resignFirstResponder];
    [_txt_surname resignFirstResponder];
    [_txt_gender resignFirstResponder];
    [_txt_dob resignFirstResponder];
    _tbl_view_gender.hidden=true;
    _txt_dob.hidden=false;
    _lbl_dob.hidden=false;

}

表格视图didSelect方法：-

-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    [_scrollview_out endEditing:YES];

    str2=[gender_arr objectAtIndex:indexPath.row];
    _txt_gender.text=str2;


    _tbl_view_gender.hidden=true;
    _txt_dob.hidden=false;
    _lbl_dob.hidden=false;
}

Answer 1

对我来说有两种选择：

1：在scrollView的superView中添加tableview

2：子类UIScrollView，覆盖方法：

 -(BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldReceiveTouch:(UITouch *)touch 
{
       //if the touch point in the tableview.
       //return NO;
       //else
       //return YES;
}

Answer 2

- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldReceiveTouch:(UITouch *)touch
{
    if ([touch.view isDescendantOfView:Your Tableview]]) {

        // Don't let selections of auto-complete entries fire the
        // gesture recognizer
        return NO;
    }

    return YES;
}
