我相信我正在跳过一个重要的步骤或者说我的财产是错误的.在我的应用程序中,在使用登录信息创建POST对象后,我无法使用映射对象中的此信息(这意味着我得到空值).我假设在创建post请求和响应请求之后,我应该能够使用我的NSObjectClass中保存的值.
我的问题
在发布请求映射后如何保存值?如果有人可以提供一个如何使用response.body值的示例,那将非常有用.谢谢.
我的课程
#import <Foundation/Foundation.h> @interface AccountsClass : NSObject @property (nonatomic,strong) Nsstring *DeviceType; @property (nonatomic,strong) Nsstring *HardwareId; @property (nonatomic,strong) Nsstring *NickName; @property (nonatomic,strong) NSNumber *HelpCreditsBalance; @property (nonatomic,assign) BOOL GotratingCreditBonus; @property (nonatomic,strong) NSNumber *AccountId; @end
这是我用于POST请求的方法
-(void)loadPostRequest { _StoreIdentifierForvendor = [[[UIDevice currentDevice]identifierForvendor]UUIDString]; _StoreTheModel = [UIDevice currentDevice].model; _nickname = usernameTextField.text; AccountsClass *AccountInfo = [[AccountsClass alloc] init]; AccountInfo.NickName = _nickname; AccountInfo.HardwareId =_StoreIdentifierForvendor; AccountInfo.DeviceType =_StoreTheModel; AccountInfo.AccountId =nil; AccountInfo.GotratingCreditBonus = FALSE; AccountInfo.HelpCreditsBalance = nil; //this is where the POST request begins RKObjectMapping *responseMapping = [RKObjectMapping mappingForClass:[AccountsClass class]]; [responseMapping addAttributeMappingsFromArray:@[@"NickName",@"HardwareId",@"DeviceType",@"AccountId"]]; NSIndexSet *statusCodes = RKStatusCodeIndexSetForClass(RKStatusCodeClassSuccessful); // Anything in 2xx RKResponseDescriptor *AccountDescriptor = [RKResponseDescriptor responseDescriptorWithMapping:responseMapping method:RKRequestMethodAny pathPattern:nil keyPath:nil statusCodes:statusCodes]; RKObjectMapping *requestMapping = [RKObjectMapping requestMapping]; // objectClass == NSMutableDictionary [requestMapping addAttributeMappingsFromArray:@[@"NickName",@"AccountId"]]; // For any object of class Article,serialize into an NSMutableDictionary using the given mapping and nest // under the 'article' key path RKRequestDescriptor *requestDescriptor = [RKRequestDescriptor requestDescriptorWithMapping:requestMapping objectClass:[AccountInfo class] rootKeyPath:nil method:RKRequestMethodAny]; RKObjectManager *manager = [RKObjectManager managerWithBaseURL:[NSURL URLWithString:@"http://10.15.1.105:XXXX"]]; [manager addRequestDescriptor:requestDescriptor]; [manager addResponseDescriptor:AccountDescriptor]; [manager postObject:AccountInfo path:@"/Accounts" parameters:nil success: ^(RKObjectRequestOperation *operation,RKMappingResult *mappingResult) { RKLogInfo(@"Load collection of Articles: %@",mappingResult.array); [self performSegueWithIdentifier:@"SegueFromLoginToWelcomeView" sender:self]; NSLog(@"the firs tobject %@",[mappingResult firstObject]); } failure:^(RKObjectRequestOperation *operation,NSError *error) { RKLogError(@"Operation Failed with error: %@",error); }]; RKLogConfigureByName("*",RKLogLevelTrace); // set all logs to trace,}
在我的下一个视图控制器中,这就是我试图获得价值的方式.
- (void)viewDidLoad { [super viewDidLoad]; // Do any additional setup after loading the view. AccountsClass *PrintloginName = [[AccountsClass alloc]init]; welcomeLabel.text =[PrintloginName NickName]; NSLog(@"visibility test %@",welcomeLabel.text); }
