MR_importFromObject 方法在 XCode7.1 beta (Swift 2.0) 中不起作用

Question

我想使用 MR_ImportFromObject 方法从字典创建实体。在我将 Xcode 6 更新为 7 之前它起作用了。但是当我使用 Xcode7 时，ImportFromObject 方法不起作用。每次调用该方法，都不会调用 willImport Delegate 方法，应用程序会崩溃。

但是 ImportFromArray 方法运行良好。

这是错误信息。我认为要点是 "swift_bridgeNonVerbatimFromObjectiveC" 和 "value type is not bridged to Objective-C".

Answer 1

尝试禁用 swift 编译器优化。我们有一个与魔法记录无关的类似崩溃，通过更改该设置得到修复。

Answer 2

我暂时从

更改了 MagicalRecord MR_importFromObject 库

id value = [objectData MR_valueForAttribute:primaryAttribute];

if (primaryAttribute != nil)
 {
      managedObject = [self MR_findFirstByAttribute:[primaryAttribute name] withValue:value inContext:context];
 }

至

 if (primaryAttribute != nil)
 {
   id value = [objectData MR_valueForAttribute:primaryAttribute];
            managedObject = [self MR_findFirstByAttribute:[primaryAttribute name] withValue:value inContext:context];
 }

您可以将其放入 NSManagedObject 的类别或扩展 (swift) 中并使用它，直到 MagicalRecord 修复此问题。这就是我要做的。这为我修复了这次崩溃。
