    <p>Because <code>UITableView</code>'s typically reuse instances of the <code>UITableViewCell</code>'s, you must ensure your '<code>-tableView:cellForRowAtIndexPath:</code> method properly sets all attributes of the cell. Else stale data can persist. I'm guessing this may be your problem, lacking a complete look at your code.</p> <p>So, something like this:</p> <pre><code>- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString* cellIdentifier = @"TheCellIdentifier"; UITableViewCell* cell = [tableView dequeueReusableCellWithIdentifier:cellIdentifier]; if (cell == nil) { cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:cellIdentifier]; } ShoppingObject* shopping = [self.myShoppingList objectAtIndex:indexPath.row]; UIImageView* accessoryView = nil; if (shopping.isDone) { accessoryView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"tick_btn"]]; } cell.accessoryView = accessoryView; return cell; } </code></pre> <p>It obtains the cell, either by from the reuse cache or by creating a new one. Then it checks the state of your data model to see if if shopping is done or not for the object being represented in that row, and if shopping is done gives you your image. Note that is shopping is not done, there is no accessoryView created, so whatever the state of the ShoppingObject is being represented at that table row, the accessoryView for that cell will be set correctly.</p> <p>So what I'd probably then do in your <code>-tableView:didSelectRowAtIndexPath:</code> would be to simply <code>-reloadData</code> on the table to ensure everything updates correctly.</p>

    1. COwell there isn't a method which checks the shoping is done or not, its user's choice to put a tick if he/she completes the task mentioned in shopping list. I mean I can't determine the the tick to be displayed, it needs to be displayed wen the row is selected.

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.
