问题描述
目标
我正在尝试保存具有 PFFile 作为属性的 PFObject.我正在为 iOS 使用新的 Local Datastore，所以我想用 saveEventually() 方法保存这个 PFObject.
问题
我遇到的问题是 saveEventually() 方法似乎不喜欢保存 PFFiles.我尝试在没有附加任何 PFFile 的情况下 saveEventually() 我的对象，并且效果很好.一旦我的 PFFile 被重新附加，Xcode 就抛出了几个断点通知(错误?)但没有终止应用程序，看起来好像一切顺利 - 但是检查解析数据浏览器确认保存没有通过.
在使用本地数据存储功能之前，我不相信这种保存是可能的 - 它会抛出 无法最终保存与新的未保存的 PFFile 相关的 PFObject." 错误.本地数据存储功能似乎已修复此问题，正如 iOS 本地数据存储文档 中所述:>
"固定一个 PFObject 是递归的，就像保存一样，所以任何对象您正在固定的那个指向的也将被固定.当一个对象被固定时，每次你通过获取或保存新数据，本地数据存储中的副本将被更新自动地.你根本不需要担心."
我已将 SDK 更新到最新版本 (v1.6.2).有任何想法吗?
解决方案 PFFiles 仍然不支持 saveEventually 见这里

您可以pinInBackgroundWithBlock，如果成功，将 PFFile 保存到您的应用程序包中的临时文件夹，并在必要或取消固定时将其删除
Goal
I am trying to save a PFObject that has a PFFile as an attribute. I am using the new Local Datastore for iOS, so I would like to save this PFObject with the saveEventually() method.
The Problem
The problem I am encountering is that the saveEventually() method doesn't seem to like saving the PFFiles. I tried to saveEventually() my object without any PFFile attached, and that worked fine. As soon as my PFFile was reattached, Xcode threw a couple of breakpoint notices (errors?) but did not terminate the app, and it appears as though all went well - however a check on the Parse Data Browser confirms that the save did not go through.
Prior to the Local Datastore feature I don't believe this save would have been possible - it would have thrown the "Unable to saveEventually a PFObject with a relation to a new, unsaved PFFile." error. It seems as though the Local Datastore feature has fixed this, as it states in the iOS Local Datastore docs:
I have updated the SDK to the latest version (v1.6.2). Any ideas?
解决方案 PFFiles still don't support saveEventually see here

You could pinInBackgroundWithBlock and if successful save the PFFile to a temporary folder in you app bundle and delete it when necessary or unpinned
