cellForRowAtIndexPath: crashes when trying to access the indexPath.row/[indexPath row]
- by Emil
Hey.
I am loading in data to a UITableView, from a custom UITableViewCell (own class and nib). It works great, until I try to access the indexPath.row/[indexPath.row].
I'll post my code first, it will probably be easier for you to understand what I mean then.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *CellIdentifier = @"CustomCell";
CustomCell *cell = (CustomCell *) [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil){
NSArray *topLevelObjects = [[NSBundle mainBundle] loadNibNamed:@"CustomCell" owner:self options:nil];
for (id currentObject in topLevelObjects){
if ([currentObject isKindOfClass:[CustomCell class]]){
cell = (CustomCell *) currentObject;
break;
}
}
}
NSLog(@"%@", indexPath.row);
// Configure the cell...
NSUInteger row = indexPath.row;
cell.titleLabel.text = [postsArrayTitle objectAtIndex:indexPath.row];
cell.dateLabel.text = [postsArrayDate objectAtIndex:indexPath.row];
cell.cellImage.image = [UIImage imageWithContentsOfFile:[postsArrayImg objectAtIndex:indexPath.row]];
NSLog(@"%@", indexPath.row);
return cell;
}
The odd thing is, it does work when it loads in the first three cells (they are 125px high), but crashes when I try to scroll down.
The indexPath is always avaliable, but not the indexPath.row, and I have no idea why it isn't!
Please help me.. Thanks.
