在类型'RKObjectManager'的对象上找不到属性'managedObjectStore' [英] Property 'managedObjectStore' not found on object of type 'RKObjectManager'
问题描述
我一直在尝试使用Restkit库的0.20.3版本.最近发生了一个错误,我无法解决.如下:
I've been attempting to work with version 0.20.3 of the Restkit library. Recently an error has occurred that I cannot figure out how to solve. It is the following:
在类型的对象上找不到属性"managedObjectStore" 'RKObjectManager *'
Property 'managedObjectStore' not found on object of type 'RKObjectManager *'
它发生在包含
objectManager.managedObjectStore = managedObjectStore;
下面列出了我的一小段代码,以帮助进行识别.我使用CocoaPods安装了所有必需的库,并且一切似乎都可以正确链接.
A small block of my code is listed below to help with identification. I used CocoaPods to install all the necessary libraries and everything seems to link properly.
#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)];
感谢您可以提供的任何输入!
Thanks for whatever input you can provide!
推荐答案
从0.20.1升级到0.20.3时,我遇到了完全相同的问题.
I had exactly the same issue when upgrading from 0.20.1 to 0.20.3.
您需要做的是在导入RestKit之前先导入CoreData.
What you need to do is to import CoreData before importing RestKit.
#import <CoreData/CoreData.h>
#import <RestKit/RestKit.h>
正在工作.
但是
#import <RestKit/RestKit.h>
#import <CoreData/CoreData.h>
不起作用.
