unable to dequeue a cell with identifier

Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'unable to dequeue a cell with identifier Cell - must register a nib or a class for the identifier or connect a prototype cell in a storyboard'

To get rid of this you can do a couple things.  First make sure your tableViewCell identifier has an identifier.  In this case it would need to be "Cell".

Next, if you are using 

dequeueReusableCellWithIdentifier:forIndexPath: 

you need to register your class in viewDidLoad with:

[self.tableView registerClass: [FontCell class] forReuseIdentifier: @"Cell"];

If you don't want to do that, you can do it the old way, but you must check if your cell is nil:

dequeueReusableCellWithIdentifier:cellIdentifier
