iOS problem with getting image to show on grouped table view

Post the header file "SettingsTableViewController.h".

If the header doesn't define a firstSection ivar (and the evidence suggests it doesn't), then this method:

- (UITableViewCell *)tableView:(UITableView *)tableView
		 cellForRowAtIndexPath:(NSIndexPath *)indexPath

will not have a variable named firstSection in scope.

The only place where you currently show a firstSection variable being declared is inside this method:

- (void)viewDidLoad

It's declared as a local variable (the default when a variable is declared inside a method or function), so its scope is limited to that method alone.

If you don't know the difference between a local variable and an instance variable, you should review the fundamentals of how and where variables are declared.

i changed the code to this
and the image shows up when you scroll past the cell and when you scroll back its there?

	UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
	if (cell == nil)
	{
		cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleValue1 reuseIdentifier:CellIdentifier] autorelease];
	}
	
	NSUInteger row =[indexPath row];
NSUInteger section = [indexPath indexAtPosition:0];
//cell.textLabel.text = [[firstSection objectAtIndex:section] objectAtIndex:row];
	
	cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
	if ([cell.textLabel.text isEqualToString:@"Email"]) {
		[cell.imageView setImage:[UIImage imageNamed:@"email.png"]];
		cell.detailTextLabel.text = @"Email Us";
		cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
	}
	if ([cell.textLabel.text isEqualToString:@"Follow Us"]) {
		[cell.imageView setImage:[UIImage imageNamed:@"twitter.png"]];
		cell.detailTextLabel.text = @"Our Twitter";
		cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
	}
	if ([cell.textLabel.text isEqualToString:@"Like Us"]) {
		[cell.imageView setImage:[UIImage imageNamed:@"facebook.png"]];
		cell.detailTextLabel.text = @"Our Facebook";
		cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
	}
	if ([cell.textLabel.text isEqualToString:@"Orange"]) {
		[cell.imageView setImage:[UIImage imageNamed:@"facebook.png"]];
		cell.detailTextLabel.text = @"Our Facebook";
		cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
	}
	if ([cell.textLabel.text isEqualToString:@"Yellow"]) {
		[cell.imageView setImage:[UIImage imageNamed:@"facebook.png"]];
		cell.detailTextLabel.text = @"Our Facebook";
		cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
	}

	[[cell textLabel] setText:contentForThisRow];
	
	NSLog(@"<<< Leaving %s >>>", __PRETTY_FUNCTION__);
	return cell;
}

You have a bunch of if statements that set the image based on the text of the string, but you set the text of the string after you go through these image statements. So the first time you make a cell, the text won't pass any of your requirements and you don't get an image. Then the second time you setup the cell, the cell will have the previous value for text (Which may or may not be the correct value for the section/row). You should move the line to set the text to before your if statments.

Also, if you have a class member variable called firstSection, and you use

NSArray *firstSection = [[NSArray alloc] initWithObjects:...];

You are creating a new pointer called firstSection, and thus the class variable never gets set you should instead use your class variable

firstSection = [[NSArray alloc] initWithObjects:...];
