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

Question

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:

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

It happens at the line containing

objectManager.managedObjectStore = managedObjectStore;

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)]; 

Thanks for whatever input you can provide!

I had exactly the same issue when upgrading from 0.20.1 to 0.20.3.

What you need to do is to import CoreData before importing RestKit.

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

is working.

but

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

is not working.

Add in build settings User Header Search Paths "${PROJECT_DIR}/Pods" recursive. This solved the problem in my case.
