unrecognized selector sent to instance 0x7ff971e1f920

Question

When I run my iOS app on the iPhone 6 simulator on Xcode 6.1 it stops on this line:

[cell configure:[feeds objectAtIndex:indexPath.row]];

Error:

'-[UITableViewCell configure:]: unrecognized selector sent to instance 0x7ff971e1f920'

Answer 1

Presumably you've defined a custom cell subclass with a configure: method.

Your subclass isn't being used - that message means you're calling the method on a plain UITableViewCell.

The most common cause of this is forgetting to set the cell class in the storyboard. Otherwise, you'll need to show how you're creating cell.

Answer 2

You have called the configure method on a UITableViewCell instance, but this class doesn't have that method. I suspect that you meant to instantiate your own UITableViewCell subclass that does have that method.
