集成设置代码导致链接器错误；删除代码，没有错误

Question

这是我试图合并到我的应用程序中的代码（从 "book" 复制和修改）（它与我在另一个应用程序（2014 年）中使用的代码基本相同，但我没有没有得到任何 build/linker 错误）：

//  Ensemble: load the model
NSManagedObjectModel *model = [NSManagedObjectModel MR_newManagedObjectModelNamed:@"Books.momd"];
[NSManagedObjectModel MR_setDefaultManagedObjectModel:model];

//  setup CoreData stack
[MagicalRecord setShouldAutoCreateManagedObjectModel:NO];
[MagicalRecord setupCoreDataStackWithAutoMigratingSqliteStoreNamed:@"bim.sqlite"];  //  enable Core Data migration

//  setup Ensemble
NSURL *modelURL = [[NSBundle mainBundle] URLForResource:@"Books" withExtension:@"momd"];
NSURL *storeURL = [NSPersistentStore MR_urlForStoreName: [MagicalRecord defaultStoreName]];

//     setup Ensemble (NOTE: the following 3 lines are causing the errors)
cloudFileSystem = [[CDEICloudFileSystem alloc] initWithUbiquityContainerIdentifier: @"iCloud.com.pragerphoneapps.BookstoreInventoryManager"];

ensemble = [[CDEPersistentStoreEnsemble alloc] initWithEnsembleIdentifier:@"BookInventoryMgr"
                                                       persistentStoreURL: storeURL
                                                    managedObjectModelURL:modelURL
                                                          cloudFileSystem:cloudFileSystem];
ensemble.delegate = self;

//  set default NSManagedObjectContext for MagicalRecord
defaultContext = [NSManagedObjectContext MR_defaultContext];  //  set default NSManagedObjectContext

//  leech it is next

我遇到了这些链接器错误：

我该如何解决这个问题？

Answer 1

找到问题...以防其他人遇到同样的问题：Link 缺少带库的二进制文件 libEnsembles.a 和 libPods.a

集成设置代码导致链接器错误；删除代码，没有错误

Ensembles setup code causes linker errors; remove the code, no errors
