Question on how to add a UIview as a subview to a UITableCell

[dragi]

Hello users,

I've got a question on how to add a UIView to a UITableViewCell.

In my learning Project I've got a UITableViewController (TableTestViewController, a UITabelViewCell.xib (MainTabelCell.xib) and a UIView (InnerTableView). My Goal ist to show the MainTableCell in the UITableView and in this MainTabelCell the InnerTabelView but I only manage to show the Cell in the Table.

TableTestViewController.h:

#import <UIKit/UIKit.h>
#import "InnerTableView.h"

@interface TableTestViewController : UITableViewController {

    UITableView *mainTable;
    UITableViewCell *nibLoadedCell;
    InnerTableView *innerView;
}

@property(nonatomic, retain) IBOutlet UITableView *mainTable;
@property(nonatomic, retain) IBOutlet UITableViewCell *nibLoadedCell;
@property(nonatomic, retain) InnerTableView *innerView;

@end

TableTestViewController.m:

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {

    static NSString *CellIdentifier = @"Cell";

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    if (cell == nil) {
        [[NSBundle mainBundle] loadNibNamed:@"MainTableCell"
            owner:self options:NULL]; 
        cell = nibLoadedCell;
    }

    // Configure the cell.
    innerView = [[UIViewController alloc] init];
    [cell addSubview: innerView.view];
    return cell;
}

Does anyone have an Idea why the innerView will not be shown in the TabelViewCell? What did I miss here? I'm still learning all that stuff but after 5 hours I don't find a clue in my Books. Hope this is not a to dumb question

Thank you

If you already have a nib-based cell, why are you manually adding a view in code? Add it to your nib.

And this:

innerView = [[UIViewController alloc] init];
[cell addSubview: innerView.view];
return cell;

...is not a good way to accomplish this. There is no reason to use an instance variable like this, and you are leaking the view.

OK,

this is basicly a test and I want to learn. What I really need is a View with it's own controller in a cell, I guess the UITableViewCell.xib is not necessary for that.
The UIview inside a Cell will be a container for a horizontal scrolling table. So that you get a UI ike the one from Pulse. But I don't get it on how to add a View to a Cell where the View has it's own Controller Class. As far as I know I have to create an instance from the controllerclass to get the View and put that one in a Cell...or not?!
I hope it becomes a bit clearer on what I try to do.

Thank you

Ok, I just realized I misread your code. You're not leaking the view, you're leaking the view controller.

But, in general it sounds like you know what to do. You really should use a property instead of the instance variable for the view controller. Is there a problem you are encountering?

OK, Now I know what you meant with the leak and I'm going to fix that. The Problem is that the UIView is not shown in the Cell and I don't know why?! I can see the Custom Cell from the nib but it has not my UIView in it at runtime.

Well, the code above you are using a generic view controller. There really isn't much to see.
