我有舊的項目寫在Objective-C上。需要遷移到Realm。RLMResults：allObjects崩潰（iOS Objective-C）
我從RLMObject創建了幾個對象/類繼承。當我只使用一個主要對象類型（ConnectionRealm）獲取對象時 - 工作正常，但如果我添加（僅添加，不包含，不使用）以投影兩個或更多其他類（繼承自RLMObject），如FloorRealm類，應用程序崩潰[ConnectionRealm allObjects]沒有任何錯誤。
還有ConnectionRealm包含RLMArray的FloorRealm。應用程序仍然崩潰。 （這幾天無法解決和理解。）謝謝。
