如何在Apportable中使用核心数据?

我尝试了完整版的apportable,我对CoreData有一个问题:

我在configuration.json上有正确的功能:

"FEATURES": ["opengles2","landscape","prefer_external_storage","write_external_storage","write_settings"],
  1. 设置我要存储数据库的storageURL:

     #ifdef ANDROID
     //tried many different locations but not luck, I think there is the problem
     NSURL *storeURL = [NSURL URLWithString:@"/data/data/com.bluepiggames.zombieSlice/files/Documents/ZS_SuperDatabase.db"];
     #else
     NSURL *storeURL = [[self applicationDocumentsDirectory] URLByAppendingPathComponent:@"ZS_SuperDatabase"];
     #endif
    
  2. 创建persistenceCoordinatore:

    NSDictionary *options = [NSDictionary dictionaryWithObjectsAndKeys:
                                 [NSNumber numberWithBool:YES],
                                 NSMigratePersistentStoresAutomaticallyOption,
                                 [NSNumber numberWithBool:YES],
                                 NSInferMappingModelAutomaticallyOption, nil];
    
    _persistentStoreCoordinator = [[NSPersistentStoreCoordinator alloc]
                     initWithManagedObjectModel: [self managedObjectModel]];
    
  3. 最后,这些是应用程序崩溃的地方:

    if (![_persistentStoreCoordinator addPersistentStoreWithType:NSSQLiteStoreType configuration:nil URL:storeURL options:options error:&error]) {
    NSLog(@"Unresolved error %@, %@", error, [error userInfo]);
    //abort();
    

    调试器中没有错误提示,只有像这样的崩溃。

    F/libc    (10177): Fatal signal 11 (SIGSEGV) at 0xe1a0d013 (code=1)
    D/dalvikvm( 7227): GC_CONCURRENT freed 387K, 12% free 6566K/7431K, paused 2ms+2ms
    D/IabHelper(10177): Querying SKU details.
    I/DEBUG   ( 8708): *** *** *** *** *** *** *** *** *** *** *** *** *** *** *** ***
    I/DEBUG   ( 8708): Build fingerprint: 'SoftWinnner/crane_a1002jhenergy/crane-a1002jhenergy:4.0.4/IMM76D/20120822:eng/test-keys'
    I/DEBUG   ( 8708): pid: 10177, tid: 10218  >>> com.bluepiggames.zombieSlice <<<
    I/DEBUG   ( 8708): signal 11 (SIGSEGV), code 1 (SEGV_MAPERR), fault addr e1a0d013
    I/DEBUG   ( 8708):  r0 63c40b68  r1 6412b13c  r2 6412b13c  r3 00000000
    
  4. (编辑)要解决此崩溃,我们必须设置之前:

      NSError *error = nil. //!!!!!
      if (![_persistentStoreCoordinator addPersistentStoreWithType:NSSQLiteStoreType configuration:nil URL:storeURL options:options error:&error])
    

    现在问题出现在另一个地方:

    // Returns the managed object model for the application.
    // If the model doesn't already exist, it is created from the application's model.
    - (NSManagedObjectModel *)managedObjectModel
    {
        if (_managedObjectModel != nil) {
            return _managedObjectModel;
        }
        NSURL *modelURL = [[NSBundle mainBundle] URLForResource:@"ZSDataModel" withExtension:@"momd"];
        NSLog(@"Test managedModel found %@",modelURL);
    
        _managedObjectModel = [[NSManagedObjectModel alloc] initWithContentsOfURL:modelURL];
        return _managedObjectModel;
    }
    

    错误是因为未找到编译的DataModel。有人知道如何将已编译的DataModel“DataModel.momod”放入一个可分配的项目中吗?

抱歉这么迟,但我不想让这个问题得不到回答。现在,momd文件不会自动添加为资产。不幸的是,每次更新xcdatamodeld时都需要手动执行。

  1. 导航到模拟器的应用程序目录(例如~/Library/Application\ Support/iPhone\ Simulator/6.1/Applications/<randomString>/<YourApp>.app/
  2. 导航到momd目录
  3. 在终端中运行以下内容:plutil -convert xml1 <ModelName>.mom -o <pathNearYourApprojFolder>/<ModelName>.mom
  4. add_params字典中的configuration.json中,然后在assets数组中,添加使用plutil转换的文件的路径<pathRelativeToApprojFolder>/<ModelName>.mom
