instantiate a subclassed uitableviewcell programatically initwithstyle does not show separator - objective-c

Question

in iOS5.0 I'm trying to instantiate a subclassed uitableviewcell programatically with initwithstyle. the code I'm using is below. When I instantiate using UITableViewCell alloc... i get the table separators, but when I do so using thumbCell alloc, the table row separator lines do not appear, the text that I setup in the thumbCell does not appear.. and the screen appears all white.. Pls help me understand what am I doing wrong..
In my ViewController
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
static NSString *identifier = #"GroupCell";
thumbCell *cell = [self.testTableView dequeueReusableCellWithIdentifier:identifier];
//UITableViewCell *cell = [self.testTableView dequeueReusableCellWithIdentifier:identifier]; (this works)
if(!cell) {
cell = [[thumbCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:identifier];
//cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:identifier];(this works)
}
[cell.textLabel setText:#"test"];
return cell;
}
and in thumbCell subclass
- (id)initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(NSString *)reuseIdentifier
{
self = [super initWithStyle:style reuseIdentifier:reuseIdentifier];
if (self) {
// Initialization code
[self.textLabel setText:#"thumbCell"];
}
return self;
}

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *identifier = #"GroupCell";
thumbCell *cell = [self.testTableView dequeueReusableCellWithIdentifier:identifier];
//UITableViewCell *cell = [self.testTableView dequeueReusableCellWithIdentifier:identifier]; (this works)
if(!cell) {
cell = [[thumbCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:identifier];
//cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:identifier];(this works)
}
NSInteger sectionRows = [tableView numberOfRowsInSection:[indexPath section]];
NSInteger row = indexPath.row;
[cell setCellBackground:sectionRows:row];
[cell.textLabel setText:#"test"];
return cell;
}
In thumbCell class (custom cell class)
-(void)setCellBackground:(NSInteger)sectionRows:(NSInteger)row
{
UIImage *rowBackground;
UIImage *selectionBackground;
if (row == 0 && row == sectionRows - 1)
{
rowBackground = [UIImage imageNamed:#"topAndBottomRow.png"];
selectionBackground = [UIImage imageNamed:#"topAndBottomRowSelected.png"];
}
else if (row == 0)
{
rowBackground = [UIImage imageNamed:#"topRow.png"];
selectionBackground = [UIImage imageNamed:#"topRowSelected.png"];
}
else if (row == sectionRows - 1)
{
rowBackground = [UIImage imageNamed:#"bottomRow.png"];
selectionBackground = [UIImage imageNamed:#"bottomRowSelected.png"];
}
else
{
rowBackground = [UIImage imageNamed:#"middleRow.png"];
selectionBackground = [UIImage imageNamed:#"middleRowSelected.png"];
}
((UIImageView *)self.backgroundView).image = rowBackground;
((UIImageView *)self.selectedBackgroundView).image = selectionBackground;
}
