Question

当我同步我的核心数据时，我的应用程序崩溃的大部分时间。所以我能做些什么来解决这个崩溃点。这个APP_DELEGATE.managedObjectContext大部分时间都崩溃了。

    NSError *error = nil;
    if (![APP_DELEGATE.managedObjectContext save:&error])
    {
        NSLog(@"ERROR while saving UserList - %@", error);
    }

保存UserList时出错 - 错误域= NSCocoaErrorDomain Code = 134030＆＃34;（null）＆＃34; UserInfo = {NSAffectedObjectsErrorKey =（＆＃34;（entity：QuizOption; id：0x7fbe5dca67a0; data：{\ n optionText = Inferior; \ n questionId = 3; \ n socialIdOption = 12; \ n}）＆＃34;）， NSUnderlyingException =无法更新从未插入的对象。}
