custom cell not being displayed - ios

Question

So i created a custom cell (using the .xib file) and linked it using a custom controller class and I also didn't forget to write in the cell identifier. I also gave the same cell identifier in my table view controller prototype cell. In the custom cell controller class I just have an outlet to a text label in the .h file. Below is the code for my table view controller. When I run the app, the custom cells are not displayed but there are cells there because i can click on them (but they are just white). What am I doing wrong, why aren't the custom cells displaying?
If I use the default cells (not custom), then everything works fine. So the problem is that I'm not using my custom cells correctly somewhere.

Answer 1

But the
[self.tableView registerNib:[UINib nibWithNibName:#"ListmaniaTableViewCell" bundle:nil] forCellReuseIdentifier:#"ListmaniaCell"];
in viewDidLoad:.

Answer 2

The code you have in tableView:willDisplayCell:forRowAtIndexPath: method should be in tableView:cellForRowAtIndexPath: method. Like this:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
ListmaniaTableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:#"ListmaniaCell" forIndexPath:indexPath];
if(!cell){
[tableView registerNib:[UINib nibWithNibName:#"ListmaniaTableViewCell" bundle:nil] forCellReuseIdentifier:#"ListmaniaCell"];
cell = [tableView dequeueReusableCellWithIdentifier:#"ListmaniaCell" forIndexPath:indexPath];
}
task *task = [self.tasks objectAtIndex:indexPath.row];
NSString *taskLabel = task.taskDescription;
cell.taskLabel.text = taskLabel;
return cell;
}

Answer 3

I figured out the problem. I had an outlet in the custom cell that was doubly linked. I also moved the line below into viewdidload as suggested by #dasdom
[self.tableView registerNib:[UINib nibWithNibName:#"ListmaniaTableViewCell" bundle:nil] forCellReuseIdentifier:#"ListmaniaCell"];
