    <p>I'm loading asynchronously images into UITableView and each row has different image. the problem is when i scroll the UITableView the previous images are loaded again in the new rows and after a while these images are changed to the correct ones (this problem is gone when i removed <strong>dequeueReusableCellWithIdentifier</strong> but it reduces the performance)</p> <pre><code>- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *cellIdentifier = @"Cell"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:cellIdentifier]; if(cell == nil) { NSArray *nibObjects = [[NSBundle mainBundle] loadNibNamed:@"CustomCellFriends" owner:self options:nil]; cell = [nibObjects objectAtIndex:0]; nibObjects = nil; } UIImageView *avatar = (UIImageView *)[cell viewWithTag:100]; UILabel *name = (UILabel *)[cell viewWithTag:2]; UILabel *city = (UILabel *)[cell viewWithTag:3]; EntryProfile *entryForRow = [entriesProfileArray objectAtIndex:indexPath.row]; avatar.image = nil; NSString *strLinkImage = [entryForRow.apiAvatarPath stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]; NSArray *args = [NSArray arrayWithObjects:avatar,strLinkImage,[NSString stringWithFormat:@"%d",indexPath.row], nil]; NSInvocationOperation *operation = [[NSInvocationOperation alloc] initWithTarget:self selector:@selector(addPhotoWithImageView:) object:args]; [operationQueue addOperation:operation]; [operation release]; // Set the name of the user name.text = entryForRow.name; return cell; } // Method - (void)addPhotoWithImageView:(NSArray *)args { UIImageView *imageView = (UIImageView *)[args objectAtIndex:0]; NSString *strLinkImage = (NSString *)[args objectAtIndex:1]; NSString *index = (NSString *)[args objectAtIndex:2]; NSData *imageData = [NSData dataWithContentsOfURL:[NSURL URLWithString:[NSString stringWithFormat:@"http://www.example.com%@",strLinkImage]]]; UIImage *imageField = [[UIImage alloc] initWithData:imageData]; if (imageData) { [imageView performSelectorOnMainThread:@selector(setImage:) withObject:imageField waitUntilDone:NO]; } [imageField release]; } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
