Question

我使用RestKit将Doctor对象发布到服务器，然后将对象保存在成功块中在调试版中，它适用于我。即使在发布版本（我使用内部发布），大多数时候它也运行良好。当发生死锁时，无论我杀了什么应用程序并重新启动它都会发生但是当我删除并重新安装它（使用相同的版本）时，它再次正常工作。这太奇怪了，我无法理解！我在CocoaPods中使用最新的RestKit（0.23.3）和MagicalRecord（2.2）。
以下是代码：

[[AccountManager cloudDataManager] postWithData:self path:path control:nil success:^(RKObjectRequestOperation *operation, id data) {
            self.doctorId = [data valueForKey:DoctorsAttributes.doctorId];
            [[self managedObjectContext] MR_saveToPersistentStoreWithCompletion:^(BOOL success, NSError *error) {
                NSAssert(error == nil, ([NSString stringWithFormat:@"%@", error]));
                if (handler != NULL) {
                    handler();
                }
            }];
        } error:self.error failure:self.failureWithNotice];

以下是错误消息：

Answer 1

当核心数据模型发生变化时，会发生这种情况。

在设置MR之前，我们应该调用[MagicalRecord setShouldDeleteStoreOnModelMismatch:YES];

因为MR不会删除默认版本中的数据

MagicalRecord saveWithOption导致发布版本死锁
