    <p>I have a TableView with custom cells containing multiple labels. I added a tapgesture on one of these labels so a popup will appear. The problem is, the popup doesn't appear where it should be (centered and on top of the label).</p> <p>What's wrong with the line:</p> <pre><code>[self.popupMenu showInView:self.view atPoint:CGPointMake(label.center.x, label.frame.origin.y)]; </code></pre> <p>tableview.m:</p> <pre><code>- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"Cell"; CustomCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath]; // add a tap gesture recognizer UITapGestureRecognizer *tapGesture = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(labelTap:)]; [cell.customAmountLabel addGestureRecognizer:tapGesture]; NSString *ItemName = [NSString stringWithCString:CurrentOrder[indexPath.row].c_str() encoding:NSUTF8StringEncoding]; NSString *ItemAmount = [NSString stringWithCString:CurrentOrder[indexPath.row].c_str() encoding:NSUTF8StringEncoding]; cell.customNameLabel.text = ItemName; cell.customAmountLabel.text = ItemAmount; return cell; } </code></pre> <p>method for tap gesture:</p> <pre><code>- (void)labelTap:(UITapGestureRecognizer *)gestureRecognizer { // get location of the swipe CGPoint location = [gestureRecognizer locationInView:self.tableCurrentOrder]; // get the corresponding index path within the table view NSIndexPath *indexPath = [self.tableCurrentOrder indexPathForRowAtPoint:location]; // check if index path is valid if(indexPath) { // get the cell out of the table view CustomCell *cell = (CustomCell *) [self.tableCurrentOrder cellForRowAtIndexPath:indexPath]; // update the cell or model std::cout &lt;&lt; CurrentOrder[indexPath.row] &lt;&lt; std::endl; UILabel *label = (UILabel *)cell.customAmountLabel; [self.popupMenu showInView:self.view atPoint:CGPointMake(label.center.x, label.frame.origin.y)]; } } </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.
