ios - 在 'managedObjectStore' 类型的对象上找不到属性 'RKObjectManager'

Question

我一直在尝试使用 Restkit 库的 0.20.3 版。最近发生了一个错误，我不知道如何解决。内容如下:

Property 'managedObjectStore' not found on object of type 'RKObjectManager *'

它发生在包含

的行

objectManager.managedObjectStore = managedObjectStore;

下面列出了我的一小段代码以帮助识别。我使用 CocoaPods 安装所有必要的库，一切似乎都正确链接。

#import "AppDelegate.h"
#import <RestKit/RestKit.h>
#import <RestKit/CoreData.h>
#import <CoreData/CoreData.h>
#import <RestKit/ObjectMapping.h>
#import "Temperature.h"

@implementation AppDelegate

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:    (NSDictionary *)launchOptions
{

    //let AFNetworking manage the activity indicator
    [AFNetworkActivityIndicatorManager sharedManager].enabled = YES;

    // Override point for customization after application launch.
    RKObjectManager *objectManager = [RKObjectManager managerWithBaseURL:[NSURL URLWithString:@"http://grid.no-ip.biz/grid"]];
    NSURL *modelURL = [NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:@"Grideye" ofType:@"momd"]];

    //Initialize managed object store
    NSManagedObjectModel *managedObjectModel = [[[NSManagedObjectModel alloc] initWithContentsOfURL:modelURL ] mutableCopy];
    RKManagedObjectStore *managedObjectStore = [[RKManagedObjectStore alloc] initWithManagedObjectModel:managedObjectModel];

    objectManager.managedObjectStore = managedObjectStore;

   // Setup our object mappings
   /**
   Mapping by entity. Here we are configuring a maping by targetting a Core Data entity with a specific
   name. This allows us to map back Sensor database objects directly onto NSManagedObject instances
   there is no backing model class
   */
   RKEntityMapping *sensorMapping = [RKEntityMapping mappingForEntityForName:@"SensorID" inManagedObjectStore:managedObjectStore];
   sensorMapping.identificationAttributes = @[ @"sensorID"];
   [sensorMapping addAttributeMappingsFromDictionary:@{
        @"sensorID" : @"sensorID",
        @"cellNum"  : @"cellNum",
        @"timeStamp": @"timeStamp",
        @"temp"     : @"temp"
        }];

   //Update date format so that we can parse Sensor dates properly
   [RKObjectMapping addDefaultDateFormatterForString:@"E MMM d HH:mm:ss Z y" inTimeZone:nil];

   // Register our mappings with the provider
   RKResponseDescriptor *responseDescriptor = [RKResponseDescriptor responseDescriptorWithMapping:sensorMapping method:RKRequestMethodGET pathPattern:@":grid" keyPath:nil statusCodes:RKStatusCodeIndexSetForClass(RKStatusCodeClassSuccessful)];

感谢您提供的任何意见!

从 0.20.1 升级到 0.20.3 时，我遇到了完全相同的问题。

您需要做的是在导入 RestKit 之前导入 CoreData。

#import <CoreData/CoreData.h>
#import <RestKit/RestKit.h>

正在工作。

但是

#import <RestKit/RestKit.h>
#import <CoreData/CoreData.h>

不工作。
