Question

I can’t get why my app crashes. Here is the code:

-(void)viewDidLoad
{
    [super viewDidLoad];

    self.tableContent = [NSArray arrayWithObjects:@"Blue", @"Yellow", @"Green", nil];
}

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
    return  [self.tableContent count];
}

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

    if (cell == nil) {
        cell = [[UITableViewCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:identifier];
    }

    return [self.tableContent objectAtIndex:indexPath.row];

}

Here is the error I got

-[NSCFString setTableViewStyle:]: unrecognized selector sent to instance 0x4938

Here’s the error in your cellForRowAtIndexPath:

return [self.tableContent objectAtIndex:indexPath.row];

tableContent is an array of NSStrings, so you’re returning an NSString instead of an object of type UITableViewCell. So instead write:

return cell;

It is the NSString you’ve returned in place of the UITableViewCell that causes the error…If you want to see the text you’re sending, you’ll need to set the textlabel’s text:

cell.textlabel.text = [self.tableContent objectAtIndex:indexPath.row];
//set the text and then return the cell
return cell;
