    <p>When i checked a cell, the image associated is changed, but when i had scrolled down and up, the cell got its default image this is my code:</p> <pre><code>- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *SimpleTableIdentifier = @"SimpleTableIdentifier"; NSArray *listData =[self-&gt;tableContents objectForKey: [self-&gt;sortedKeys objectAtIndex:[indexPath section]]]; UITableViewCell * cell = [tableView dequeueReusableCellWithIdentifier: SimpleTableIdentifier]; if(cell == nil) { cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:SimpleTableIdentifier]; } NSUInteger row = [indexPath row]; cell.textLabel.text = [listData objectAtIndex:row]; UIImageView *unchecked = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"unchecked.png"]]; UIImageView *checked = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"checked.png"]]; BOOL bChecked = NO;//By default, it's unchecked, so NO /// Assign cell according to `bChecked` cell.accessoryView = (bChecked ? checked : unchecked); return cell; } </code></pre> <p><strong>EDIT:</strong></p> <p>I have edited my code to look as above, but i still get the issue, the default image is getting back when i scroll up my table view.</p> <p><strong>EDIT 2:</strong> @Openside: So according to your approach, my snippet should look like this:</p> <pre><code>- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *SimpleTableIdentifier = @"SimpleTableIdentifier"; NSArray *listData =[self-&gt;tableContents objectForKey: [self-&gt;sortedKeys objectAtIndex:[indexPath section]]]; UITableViewCell * cell = [tableView dequeueReusableCellWithIdentifier: SimpleTableIdentifier]; if(cell == nil) { cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:SimpleTableIdentifier]; } NSUInteger row = [indexPath row]; textClass *myText = (textClass*)[listData objectAtIndex:row]; cell.textLabel.text = myText.text; UIImageView *unchecked = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"unchecked.png"]]; UIImageView *checked = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"checked.png"]]; cell.accessoryView = (myText.isChecked ? checked : unchecked); return cell; } - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { textClass *myText=[[textClass alloc]init]; myText.isChecked=YES; } </code></pre> <p>I got this exception:</p> <pre><code>Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[__NSCFConstantString text]: unrecognized selector sent to instance 0x673bc' </code></pre> <p>The line indicating the exception issue is this (in <code>cellForRowAtIndexPath</code> delegate method):</p> <pre><code>cell.textLabel.text = myText.text; </code></pre> <p>I have added the class textClass although i am not so convinced, i think i can use a property in the holder class of my UITableView.</p>

    1. COThe issue is that your listData object isn't being created with a collection (array) of textClass items hence the exception. You you should create a class level variable for listData populate it in loadView with textClass items setting the text to your text value and isChecked = NO.

Guidance
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.
