ios - 从服务 Objective-C 获取数据

Question

我是 iOS 新手，在显示来自以下服务数据的数据时遇到问题

[{
    "Name": Rahul,
    "FatherName": Ravinder,
    "Designation": Engineering,
    "Profession": Software Eng,
    "Height": "5 ft 3 in",
    "Weight": "134.5 lbs"
}]

下面是我试过的代码。请帮我找出问题所在。提前致谢。

 NameDetails.m
---------------

- (void)viewDidLoad {
    [super viewDidLoad];
    [self callService:[appDelegate.signUpdata objectForKey:@"id"]];
}

-(void)callService:(NSString *)userid
{
    [Utility showIndicator:nil view1:self.view];
    JsonServicePostData = [[JsonServiceCls alloc] init];
    JsonServicePostData.delegate = self;
    [JsonServicePostData Getdata:userid];
}

-(void)DidFinishWebServicesPostData
{
    [Utility hideIndicator];

        NSMutableDictionary *dict = [[NSMutableDictionary alloc]init];
        _txtName.text=[dict objectForKey:@"Name"];
        _txtFName.text=[dict objectForKey:@"FatherName"];
        _txtDesg.text=[dict objectForKey:@"Designation"];
        _txtprof.text=[dict objectForKey:@"Profession"];
        _txtHeight.text=[dict objectForKey:@"Height"];
        _txtWeight.text=[dict objectForKey:@"Weight"];

    }

}

+(void)makeHttpGETresponceParsingwithSerVer:(NSString *)strServer withCallBack:(void(^)(NSDictionary *dicArr,NSError *error))handler
{

NSURL *urlServer = [NSURL URLWithString:strServer];

    NSURLRequest *request = [NSURLRequest requestWithURL:urlServer];

    NSURLSession *session = [NSURLSession sharedSession];

    NSURLSessionDataTask *postDataTask = [session dataTaskWithRequest:request completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) {

            NSDictionary *res = [NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingAllowFragments error:&error];


            handler(res,error);


    }];

    [postDataTask resume];
}
then call your method In viewDidLoad...

[RestClient makeHttpGETresponceParsingwithSerVer:@"YOUR_URL" withCallBack:^(NSDictionary *responceDic, NSError *error) {

    _txtName.text   =[responceDic objectForKey:@"Name"];
    _txtFName.text  =[responceDic objectForKey:@"FatherName"];
    _txtDesg.text   =[responceDic objectForKey:@"Designation"];
    _txtprof.text   =[responceDic objectForKey:@"Profession"];
    _txtHeight.text =[responceDic objectForKey:@"Height"];
    _txtWeight.text =[responceDic objectForKey:@"Weight"];

}];

//RestClient是类名，因为它是类方法，可以使用实例方法。
