Question

I would like to know where to enter custom code to change the value of a Label property for a UITableViewCell.

I am not sure how this is loaded, as I have put an NSLog in the ViewDidLoad and (id)initWithStyle instance methods but neither write to the log.

I have setup a NIB and custom class all correctly linked, and the Label is linked as a property and no longer causes an error. But I am unable to setText.

This is how the custom cell is called:

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = @"Cell";
LeftMenuTableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];

if (cell == nil) {

    NSArray* views = [[NSBundle mainBundle] loadNibNamed:@"LeftMenuTableViewCell" owner:nil options:nil];

    for (UIView *view in views) {
        if([view isKindOfClass:[UITableViewCell class]])
        {
            cell = (LeftMenuTableViewCell*)view;

        }
    }
}

return cell;
}

This is the code in the IMP file for the LeftMenuViewCell class.

-(void)viewDidLoad {

displayName.text = [self.user objectForKey:@"displayName"];

I can set the displayName to a string and this does not change either. If I add an NSLog to the viewDidLoad for the custom cell class it is not shown, like it is not loaded, but the cell is loaded…?

Let’s say that you have custom UITableViewCell with UILabel called testLabel. If your NIB and custom class are properly linked than you can use following code:

MyTableViewCell.h

@interface MyTableViewCell : UITableViewCell

@property (nonatomic, assign) IBOutlet UILabel *testLabel;

@end

cellForRowAtIndexPath in your UITableViewController or UIViewController:

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
 {
      static NSString *CellIdentifier = @"MyTableViewCellId";
      MyTableViewCell *cell = (MyTableViewCell *)[tableView dequeueReusableCellWithIdentifier:CellIdentifier];

      if (cell == nil) {
          NSArray *topLevelObjects = [[NSBundle mainBundle] loadNibNamed:@"MyTableViewCell" owner:self options:nil];
         cell = [topLevelObjects objectAtIndex:0];    
      }

      [cell.testLabel.text = [_dataSource objectAtIndex:[indexPath row]]];

      return cell;
}

Hope it helps 🙂
