  • Error invoking method 'addSubview:' on 'UIWindow' because -[??? superview]: unrecognized selector sent to instance

If you are trying to add a UIViewController, make sure you are adding the view, not the viewController.

  • -[NSCFNumber isEqualToString:]: unrecognized selector sent to instance 0xXXXXXXXX

Obj-C expects a string but you sent it something else. If you want to send a number as a string use the tonumber() function first.

  • Why isn't my delegate/datasource method being called?

Did you declare the protocols in your waxClass? waxClass"MyController", UI.TableViewController, protocols={"UITableViewDelegate", "UITableViewDataSource"}}
