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,我不知道如何解决。如下:
在“RKObjectManager *”类型的对象上找不到属性“managedObjectStore”
它发生在包含
objectManager.managedObjectStore = managedObjectStore;
下面列出了我的一小部分代码,以帮助识别。我使用 CocoaPods 安装了所有必要的库,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)];
