未调用cellForRowAtIndexPath，但为UITableView调用的numberofRowsInSection已添加为UIView的子视图

Question

I have created custom alert view where i want to add the UITableView as subview.I haven't created UITableView through (IB) but created programmatically,Also I have implement protocol UITableViewDelegate and UITableViewDataSource in UIView .But the method cellForRowAtIndexPath not called. I think the problem is here i have to create UITableView through IB make it visible.is it possible not to create through IB but using below code and implement the delegate methods.

Here is the code

        privacy_tableview = [[UITableView alloc] initWithFrame:CGRectMake(10.0, 0.0, alert_width-40.0, 0.0)];                          [privacy_tableview sizeToFit];
        privacy_tableview.frame = CGRectMake(10.0, 0.0, alert_width-40.0, privacy_tableview.frame.size.height);

       //Add scrollview which contain uitableview
        MsgScrollView = [[UIScrollView alloc] initWithFrame:CGRectMake(10.0, alert_height, alert_width-20.0, (privacy_tableview.frame.size.height>max_msg_height)?max_msg_height:privacy_tableview.frame.size.height)];

        [privacy_tableview setDataSource:self];
        [privacy_tableview setDelegate:self];

        [privacy_tableview reloadData];

Answer 1

The height of the table is zero privacy_tableview.frame.size.height = 0.0 and according to table view programming basics for iOS, only visible cells are created and shown in table.

So, increasing the height to at least a row's height could call cellForRowAtIndexPath method of the TableView.
