UITableViewCell无法添加子视图

Question

I want to add a Button in a TableView cell.

At the beginning, I was using a TableView and its cell from the Storyboard, and it was working.

I removed the TableView from the Storyboard, to add the TableView programmatically, and I created the cell in a XIB.

I did this to switch between a TableView displaying, and a CollectionView displaying.

Then, I use the same code to create the button I want to display in the CollectionViewCell and the TableViewCell. It works for the Collection, not for the Table. I added checkBoxButton.backgroundColor = [UIColor blueColor]; and I don't see the blue square.

NSLog(@"Cell subviews before %i", [cell.contentView.subviews count]);

    UIButton *checkBoxButton = d[@"Button"];
    if(checkBoxButton){
        checkBoxButton.frame = CGRectMake(850,60, 50, 50);
        checkBoxButton.backgroundColor = [UIColor blueColor];
        [cell.contentView addSubview:checkBoxButton];
    }

NSLog(@"Cell subviews after %i", [cell.contentView.subviews count]);
    return cell;

I've a label named LIB_Nom in the cell. If I use [LIB_Nom addSubview:checkBoxButton], the button appears. (same for all elements of the cell.)

Please help me, I'm raging for two hours. Thanks :)

Here's my cellForRowAtIndexPath

        CellIdentifier = @"personne_Table";
        CELL_Personne_Table *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];
        CLASS_Contact* unContact = [tab_Personnes objectAtIndex:[indexPath row]];
        NSDictionary* d = [self loadCellPersonne:indexPath];

        cell.LIB_Nom.text = d[@"Nom"];
        cell.LIB_Contact.text = d[@"Contact"];
        cell.LIB_Adresse.text = d[@"Adresse"];
        cell.LIB_Adresse_2.text = d[@"Adresse2"];
        cell.LIB_CP_Ville.text = d[@"CP_Ville"];
        cell.LIB_ID.text = d[@"ID"];
        cell.LIB_Tel_1.text = d[@"Tel"];
        cell.LIB_Tel_2.text = d[@"Tel_2"];
        cell.LIB_Email.text = d[@"Email"];
        cell.LIB_DateCreation.text = d[@"DateCreation"];
        cell.IMG_Rdv.hidden = [unContact Get_HideRdV];
        cell.IMG_Pays.image = d[@"IMG_Pays"];
        cell.IMG_Contact.image = d[@"IMG_Contact"];
        cell.LIB_Visite.text = d[@"Visite"];

        for(UIView* v in cell.subviews)
        {
            NSLog(@"Cell Subview %p", v);
        }
        UIButton *checkBoxButton = d[@"Button"];
        if(checkBoxButton){
            checkBoxButton.frame = CGRectMake(0,0, 50, 50);
            checkBoxButton.backgroundColor = [UIColor blueColor];

            NSLog(@"content View %p", cell.contentView);
            cell.contentView.backgroundColor = [UIColor redColor];
            [cell.contentView addSubview:checkBoxButton];
        }
        NSLog(@"-------------------");

        return cell;

Here, I create the Tableview

TABLE_Contacts = [[UITableView alloc] initWithFrame:f];
        TABLE_Contacts.backgroundColor = [UIColor clearColor];
        TABLE_Contacts.delegate = self;
        TABLE_Contacts.dataSource = self;
        [TABLE_Contacts registerNib:[UINib nibWithNibName:@"CELL_Personne_Table" bundle:nil] forCellReuseIdentifier:@"personne_Table"];
        [self.view addSubview:TABLE_Contacts];

Answer 1

Try this:

• In your xib, create all the subviews you may want to use at runtime and hide them.
• Place them under the contentView (in the xib)
• Connect them into your custom cell class by ctrl-dragging into your code.
• At runtime, just hide/unhide the appropriate views in response to the action.

This way, the process of loading the xib creates and hooks everything up for you. All you need to do is register the xib with the collectionView.
