containerURLForSecurityApplicationGroupIdentifier在iOS模拟器上返回nil [英] containerURLForSecurityApplicationGroupIdentifier returns nil on iOS Simulator

问题描述

借助iOS8和扩展，Apple推出了App组容器（此处有更多信息）。

With iOS8 and extensions Apple introduced the App group containers (more info here).

我们通过 NSFileManager 的 containerURLForSecurityApplicationGroupIdentifier：方法使用它。它适用于AppStore（iOS8和iOS7）的生产。问题是因为我们的团队更新到 Xcode 6.1（6A1052d），该方法在模拟器上返回 nil 。

We use it through NSFileManager's containerURLForSecurityApplicationGroupIdentifier: method. It works well in production on AppStore (with both iOS8 and iOS7). Problem is since our team updated to Xcode 6.1 (6A1052d), the method returns nil on Simulators.

我们搜索了很多，但我们找不到任何线索。即便如此问题或这个在这里不适用。

We searched a lot but we didn't manage to find any clues. Even this question or this one are not applicable here.

NSFileManager 的 containerURLForSecurityApplicationGroupIdentifier：方法适用于您的模拟器？有没有办法解决这个问题？

Does NSFileManager's containerURLForSecurityApplicationGroupIdentifier: method works on your simulators? Is there any way to fix that?

推荐答案

我能够解决这个问题。文档说

I was able to solve this problem on my side. The documentation says

您的应用必须具有指定应用程序组的com.apple.security.application-groups权利
。 https://developer.apple.com/library/mac/documentation/Cocoa/Reference/Foundation/Classes/NSFileManager_Class/index.html#//apple_ref/occ/instm/NSFileManager/containerURLForSecurityApplicationGroupIdentifier ：

在我的应用程序中的某个时刻，我已从我的应用目标/构建设置/代码签名/代码签名权利中删除了权利文件。调试和发布都必须包含YOUR_APP.entitlements文件。我的调试不包括它所以它不适用于模拟器

At some point in my app, I had removed the entitlements file from my app target/build settings/code signing/code signing entitlements . Both debug and release must include YOUR_APP.entitlements file . My debug wasn't including it so it wasn't working on simulator
