UITableViewCell subclass with UIImageView proper way to reuse

I have a

subclass. I want to add a
as a subview, but make sure to do proper reuse so that I am not adding the subview over and over. I also want to make sure to nil out the image in

What is the proper method for doing this?

Answer Source

In your custom cell subclass you should add any required views in the initWithStyle:reuseIdentifier: method. As long as you have registered your cell class against the reuse identifier in your table view then this initialiser will be called by dequeueReusableCellWithIdentifier:forIndexPath: whenever a new cell is required. This method will not be called when a cell is reused, so your image view won't be added more than once.

You can clear the image view's current image in the cell class's prepareForReuse method.
