UITableViewCell is redrawing on dequeue

My setup

I have a UITableViewCell that is in my main storyboard in a UITableViewController. It gets populated with some JSON data pulled from a REST API that will cause each cell to be a variable height. There are UIImageViews, UILabels, all of different heights and styles, think Instagram-esque.

My problem

When I scroll to maybe the 5th or 6th cell, then go back up, they start redrawing and overlapping, so text gets mixed, lines get redrawn, etc.

What I've tried

This seems like a common problem on SO, so I've tried several posted solutions. It seems like my issue is probably the same problem as others face, which is, I am calling addSubview on my cell every time it dequeues, but I've tried checking to see if the cell already exists. I came across another post somewhere (sorry, I can't remember where), that suggests that because I am creating this in the storyboard, it is already initialized and if ( !cell ) will already return false, so I don't know how to prevent it from redrawing.

When I try removing the cell from the storyboard, and creating it programmatically, I get an error saying it can't find a cell with my identifier @"Cell".

I've also tried someone's solution of removing all subviews when I dequeue, so I used: for ( UIView *view in cell.contentView.subviews ) { if ([view isKindOfClass:[UIView class]]) { [view removeFromSuperview]; } }

and it doesn't find anything.
