iPhone 应用程序因 coreData 错误而崩溃

Question

我们应用程序的第一个版本已在应用程序商店中发布。为了使应用程序国际化，对应用程序使用的核心数据模型进行了一个微小的更改，该更改是 - 添加到其中一个实体的新属性。

我通过向核心数据添加新的版本控制模型并将当前的 Core DataModel 设置为创建的新版本来进行更改。

为了进行轻量级迁移，我还添加了所需的选项，如下所示:

NSDictionary *options = [NSDictionary dictionaryWithObjectsAndKeys:
    [NSNumber numberWithBool:YES],    NSMigratePersistentStoresAutomaticallyOption,
    [NSNumber numberWithBool:YES], NSInferMappingModelAutomaticallyOption, nil];
NSError *error = nil;
__persistentStoreCoordinator = [[NSPersistentStoreCoordinator alloc]  initWithManagedObjectModel:[self managedObjectModel]];
[__persistentStoreCoordinator addPersistentStoreWithType:NSSQLiteStoreType configuration:nil URL:storeURL options:options error:&error];

在模拟器中测试和在设备上测试(连接到 MAC 时)时，所有这些工作正常。一旦我制作了 ipa 文件并将其安装到设备上，应用程序在启动时就崩溃了。显示 default.png 文件，然后不加载其他 View 。

应用程序崩溃日志显示了 CoreData 的一些问题，但我无法指出这就是导致问题的原因。崩溃日志如下所示:

"2 CoreData   0x324ee491 -[NSManagedObjectModel(_NSInternalMethods) _setIsEditable:] + 1" 

表明核心数据存在一些问题，但我不知道什么也不知道我需要做什么来解决这个问题。有什么想法吗？

Answer 1

我花了很长时间才发现这个问题。

正在使用构建脚本构建 ipa 文件，这是由构建错误引起的。

构建的.ipa文件不包含第二个版本的核心数据。所以应用程序总是崩溃。
