    If you look at the Apple documentation, you’ll see that dequeueReusableCellWithIdentifier: forIndexPath: came in with iOS 6.0.

    That means if you try to call this method on iOS 5.X devices, it’s going to throw an exception.

    It would be better if you used the older “dequeueReusableCellWithIdentifier:“ call if possible.

    One big difference between the two calls is that the latter (older) one can return nil, in which case you need to alloc/init a new reuseable cell.
