iCloud错误“操作无法完成.(LibrarianErrorDoman错误10-无法配置集合.) [英] iCloud Error "The operation couldn't be completed. (LibrarianErrorDoman error 10 - Unable to configure the collection.)"

问题描述

我想将现有应用程序迁移到iCloud.

i want to migrate my existing app to iCloud.

在尝试学习操作时，我尝试了一个示例应用程序，该应用程序已按照演示中的描述进行了工作(如iTunes stanford大学课程的第17讲所示).

in my attempt to learn what to do, i have tried a sample app that has worked as described in the demo (as seen in lecture 17 of the iTunes stanford university course).

遇到此问题的人可以帮助我诊断我为使以下操作失败而搞砸了哪一步?这基本上是在告诉我没有要查询的数据吗?还是发生其他未正确配置的事情?

can someone who has had this problem help me diagnose what step i messed up to cause the following to fail? is this just telling me basically that there's no data to query? or is there something else going on that i haven't properly configured?

我在控制台中得到以下内容(在我调用 [self.iCloudQuery startQuery];

i am getting the following in my console (which occurs in the code below immediately after i call [self.iCloudQuery startQuery];

item update error: 0, Error Domain=LibrarianErrorDomain Code=10 "The operation couldn’t be completed.
(LibrarianErrorDomain error 10 - Unable to configure the collection.)" UserInfo=0x11ee00 {NSDescription=Unable to
configure the collection.}

我创建了一个开发配置文件，该文件在iTunes Connect上启用了iCloud.

i created a development provisioning profile that has iCloud turned on on iTunes connect.

我启用了权利.这里是内容:

i turned on entitlements. here are the contents:

推荐答案

对于遇到此问题的其他人……显然，这是当您未在要测试的设备上启用iCloud时发生的错误.一旦我在设备上启用了iCloud，该错误就会停止在我的日志中发生.

for anyone else running into this … apparently, this is the error that occurs when you haven't enabled iCloud on the device on which you are testing. once i enabled iCloud on the device, the error stopped occurring in my log.

所以现在我知道要检查什么错误才能向用户显示一个对话框，提示您在系统首选项中注册iCloud之前，无法连接到iCloud".

and so now i know what error to check for in order to present the user with a dialog saying "connecting to iCloud won't work until you sign up for iCloud in the system preferences".
