我在 XCode 中有 2 个错误,并试图弄清楚它们的含义。
第一个:
2009-06-30 18:56:27.998 Spark[4584:10b] Error setting value for key path filterPredicate of object <NSArrayController: 0x1482c0>[entity: group, number of selected objects: 1] (from bound object <NSSearchField: 0x143f20> with object ID 1387 in Nib named MainMenu.nib): [<NSManagedObject 0x1d8170> valueForUndefinedKey:]: the entity group is not key value coding-compliant for the key keyPath.
第2个:
