UIPicker视图和UITable视图

我在UIPickerview和UITableview中都遇到常见错误，即
Terminating app due to uncaught exception \'NSUnknownKeyException\', reason: \'[<UIViewController 0x4d32080> setValue:forUndefinedKey:]: this class is not key value coding-compliant for the key CurrencyPicker.\'
Terminating app due to uncaught exception \'NSUnknownKeyException\', reason: \'[<UIViewController 0x4b2c070> setValue:forUndefinedKey:]: this class is not key value coding-compliant for the key tableView.\'
