This answer probably won't be of much help to you, but it may be to others. IF you make a subclass, you can specify the appearance for each subclass separately. For instance, I have UITableviewCells and a custom class that is derived from UITableViewCells. I actually do this for a reason, but I discovered that i need to call [[UITableViewCells appearance] setFont:[...]] for both classes specifically.

Since you seem to want to do so based upon a variable that you will not know until runtime, you are probably out of luck!
