Web Services restkit 10.0中的RKObjectMappingMap问题

我对新的restkit 10.0中的RKObjectMapping感到困惑。我已经用RKClient调用了我的Web服务，并得到了JSON格式的响应。现在我想用我的User类MapJSON字符串。如何做到这一点？

{"id":2,"displayName":"Giri Bhushan","roles":null,"username":"FBUser-123456","password":"dddddddddddddddd=\r\n","email":"test@gmail.com","gender":"M","birthDate":null,"friends":null,"bloodGroup":null,"firstName":null,"lastName":null,"phoneNumber":null}

我已经尝试了下面的代码：

RKObjectMapping* userMapping = [RKObjectMapping mappingForClass:[User class]];
[userMapping mapKeyPath:@"id" toAttribute:@"userId"];

[userMapping mapKeyPath:@"displayName" toAttribute:@"displayName"];
[userMapping mapKeyPath:@"userName" toAttribute:@"userName"];
[userMapping mapKeyPath:@"password" toAttribute:@"password"];
[userMapping mapKeyPath:@"email" toAttribute:@"email"];
[userMapping mapKeyPath:@"gender" toAttribute:@"gender"];
[userMapping mapKeyPath:@"birthDate" toAttribute:@"birthDate"];
[userMapping mapKeyPath:@"bloodGroup" toAttribute:@"bloodGroup"];
[userMapping mapKeyPath:@"firstName" toAttribute:@"firstName"];
[userMapping mapKeyPath:@"lastName" toAttribute:@"lastName"];

[userMapping mapKeyPath:@"phoneNumber" toAttribute:@"phoneNumber"];

[[RKObjectManager sharedManager].mappingProvider setMapping:userMapping forKeyPath:@"user"];

但是，如何使用RKObjectMappingMapJSON字符串呢？

如果您在JSON的根级别有 users，则应该使用以下代码：

RKObjectManager *manager = [RKObjectManager sharedManager];
RKManagedObjectMapping *userMapping = [RKManagedObjectMapping mappingForClass:[User class] inManagedObjectStore:manager.objectStore];
[userMapping mapKeyPath:@"id" toAttribute:@"userId"];
[userMapping mapAttributes:@"displayName",@"userName",@"password", nil]; // Add other attributes
[manager.mappingProvider setMapping:userMapping forKeyPath:@""];

您缺少此行：
[[RKObjectManager sharedManager] loadObjectsAtResourcePath:@"" delegate:self];
然后实现其委托方法，如下所示：
(void)objectLoader:(RKObjectLoader *)objectLoader didLoadObjects:(NSArray *)objects{ NSLog(@"Objects Retrieved: %d\n%@", objects.count, objects); YourObject* obj = [objects objectAtIndex:0];

NSString* info = [NSString stringWithFormat:
                  @"Value 1 is %@\n"
                  @"Value 2 is %@\n"
                  @"Value 3 is: %@",
                  [obj value1],
                  [obj value2],
                  [obj value3];

}`
希望这对你有用。XD
