Question

我对新的restkit 10.0中的RKObjectMapping感到困惑。我用RKClient调用了我的web服务，并以JSON的形式得到了响应。现在我想用我的User类映射JSON字符串。怎么做？

块引用 {“id”：2，“displayName”：“Giri Bhushan”，“roles”：null，“username”：“FBUser-123456”，“password”：“dddddddddddddddddd = \ r \ n”，“email”：“ test@gmail.com”， “性别”： “M”， “生日”：空， “朋友”：空， “bloodGroup”：空， “名字”：空， “姓氏”：空， “phoneNumber的”：空}

我尝试使用以下代码：

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RKObjectMapping映射JSON字符串？

Answer 1

如果您在JSON的根级别有用户，则以下内容应该有效：

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:@""];

Answer 2

你错过了这一行：
[[RKObjectManager sharedManager] loadObjectsAtResourcePath:@"" delegate:self];

然后实现其委托方法，如：
(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];

}`

希望这适合你。 XD
