    copied!<p>I am fairly new to RestKit framework. I am facing difficulty in parsing some JSON response.</p> <pre><code>{ "success": "1", "loginStatus": "Success", "sessionToken": "NTE5YTg5NjE4ZDIxYzQ3YzMUybdtsUU8989GVmaW5lZHwxMzY5ODE0MTc4Mzgw", "user": { "ActivationMethod": false, "ActivationToken": "iey4C5E3iMt7mXZL", "Active": true, "FirstName": "John", "LastName": "Doe", } } </code></pre> <p>This is response of my Login web service.</p> <p>What I want is to have value of sessionToken, FirstName and LastName to be mapped in one class. For this I have created a class User</p> <pre><code>@interface User : NSObject @property (nonatomic, strong) NSString* firstName; @property (nonatomic, strong) NSString* lastName; @property (nonatomic, strong) NSString* sessionToken; @end </code></pre> <p>For the mapping I have tried following code :</p> <pre><code> RKObjectMapping* mapping = [RKObjectMapping mappingForClass:[User class]]; [mapping addAttributeMappingsFromDictionary:@{ @"FirstName": @"firstName", @"LastName": @"lastName", @"sessionToken" : @"sessionToken", }]; RKResponseDescriptor *responseDescriptor = [RKResponseDescriptor responseDescriptorWithMapping:mapping pathPattern:@"/login" keyPath:nil statusCodes:RKStatusCodeIndexSetForClass(RKStatusCodeClassSuccessful)]; [objectManager addResponseDescriptor:responseDescriptor]; </code></pre> <p>Using this I getting values of Lastname and Firstname as null. </p> <p>The url is http://[BASE URL]/login</p> <p>I have gone through this <a href="https://github.com/RestKit/RestKit/wiki/Object-mapping" rel="nofollow">link</a> on object mapping but could resolve this issue.</p> <p>Any pointers in this regard will be very helpful</p> <p>Regards,</p> <p>tek3</p> <p><em><strong></em>**<em>*</em>**<em>*</em>**<em>*</em>**<em>*</em>**<em></strong> EDIT <strong></em>**<em>*</em>**<em>*</em>**<em>*</em>**<em>*</em>****</strong></p> <p>I am now able to get the values using code below.</p> <pre><code> RKObjectMapping* userMapping = [RKObjectMapping mappingForClass:[User class] ]; [userMapping addAttributeMappingsFromDictionary:@{ @"FirstName": @"firstName", @"LastName": @"lastName", }]; RKObjectMapping* loginMapping = [RKObjectMapping mappingForClass:[Login class] ]; [loginMapping addAttributeMappingsFromDictionary:@{ @"sessionToken": @"sessionToken", }]; [loginMapping addPropertyMapping:[RKRelationshipMapping relationshipMappingFromKeyPath:@"user" toKeyPath:@"user" withMapping:userMapping]]; RKResponseDescriptor *responseDescriptor = [RKResponseDescriptor responseDescriptorWithMapping:loginMapping pathPattern:@"/login" keyPath:nil statusCodes:RKStatusCodeIndexSetForClass(RKStatusCodeClassSuccessful)]; </code></pre> <p>But I still have one confusion. I had to create another Login as</p> <pre><code>@interface Login : NSObject @property (nonatomic, strong) NSString* sessionToken; @property (nonatomic, strong) User* user; @end </code></pre> <p>Login is having an object of User class as property. Is there any way that I get values of all the keys in JSON response by simply creating a single object and not multiple nested objects?</p>
