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

Question

我一直在尝试使用Restkit库的0.20.3版本.最近出现了一个错误,我无法弄清楚如何解决.它是以下内容:

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

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来安装所有必需的库,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)];

感谢您提供的任何输入!

Answer 1

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>

工作中.

但

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

不管用.

Answer 2

添加构建设置用户标题搜索路径 "$ {PROJECT_DIR}/Pods"递归.这解决了我的问题.

Answer 3

添加

#import <CoreData/CoreData.h>  

到您的 .pch 文件。
