指向没有明确所有权的非常量类型“id”的指针xcode

Question

我有一个在各种设备上运行良好的应用程序，但是当我尝试在模拟器上运行它时出现以下错误。

指向没有明确所有权的非常量类型“id”

我知道应该从哪里删除 id* 中的 * 来解决问题，但是 id* 位于 coreData.h 中，所以我无法更改它。

我怎样才能摆脱这个错误？

在 NSFetchRequest.h 中有一行 id*_additionalPrivateIvars; （这是错误的来源）

它是框架coreDate/coreData.h中的一个头文件

这个框架被导入到我的一个视图控制器中

coreData 中的其他人是 id** _kvcpropertyAccessors；在 NSEntityDescription.h 和 id_optimizationHints;在 NSManagedObjectModel.h 和 id_cachedObsInfoByEntity；和 id*_contextLabel;在 NSManagedObject.h 和 id _additonalPrivateIvars;在 NSPersistentStoreCoordinator.h 内 和 id _oidFactories;在 NSPersistentStore.h 中

不知道这是否有帮助，但是...

所有这些都与将视频上传到 youtube 有关

我没有所有设备，所以我必须在模拟器上运行应用程序，主要是查看不同的视图，以确保一切正常。我不能使用自动调整大小，因为当视图运行时我有各种动画，并且它们必须根据设备定位不同的东西。

任何帮助将不胜感激。

好的，这里是 coreData/NSEntityDescription.h 中上下文中的代码

#import <Foundation/NSArray.h>
#import <Foundation/NSDictionary.h>
#import <Foundation/NSRange.h>

这是一个例子。很抱歉有这么多代码，但我想我应该包含所有内容供您查看

我怀疑问题是因为编译器对于使用的 SDK 来说太新了。新的 clang 将启用 ARC，但旧的 SDK 无法使用 ARC 进行编译。
