使用AFNetworking和model进行JSON解析类

问题描述：

我在使用Model获取数据和将数据从json显示到我的应用程序时感到有点困惑。使用AFNetworking和model进行JSON解析类

我有这样的JSON数据：

{ 
result 
[ 
    { 
     key : value 
     key : value 
     key : value 
    } 
    { 
     key : value 
     key : value 
     key : value 
    } 
]

}

我想这样的代码：

json = [[NSMutableArray alloc]init]; 
      NSError *writeError = nil; 
      NSData *jsonData = [NSJSONSerialization dataWithJSONObject:responseObject options:NSJSONWritingPrettyPrinted error:&writeError]; 

      NSDictionary *dic = [NSJSONSerialization JSONObjectWithData:jsonData 
                   options:NSJSONReadingMutableContainers 
                    error:&writeError]; 


      json = dic[@"Result"]; 
      int i; 
      for (i = 0; i <= json.count; i++) 
      { 
       NSMutableArray *array = json[i]; 
       [json enumerateObjectsUsingBlock:^(id obj, NSUInteger index, BOOL *stop) 
       { 
        // Dim = [[DimEntityFull alloc]initWithJSONDictionary:obj]; 
         saveSearch = [[SaveSearchMaster alloc]initWithJSONDictionary:obj]; 
       } ]; 
      }

我使用 “AFNetworking” 和我试图获取数据并存储到模型类中，然后显示为自定义单元标签。

我怎样才能得到它。

谢谢。

您是否尝试过在提取的每个阶段记录的数据？ – ZeMoon

是的，但它不适合我。我对如何存储模型类感到困惑。 –

我知道arrayOfRecords = [jsonData objectForKey：@“result”];然后cell.lblName.text = [[arrayOfRecords objectAtIndex：indexPath.row] valueForKey：@“name”];是正确的流程。但与模型类我怎么能得到相同的结果？ –

在您的视图控制器

- (void)viewDidLoad 
{ 
    [super viewDidLoad]; 


    [self getUsersList]; 
} 

-(void)getUsersList 
{ 



    AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager]; 
    manager.responseSerializer = [AFJSONResponseSerializer serializer]; 
    manager.responseSerializer.acceptableContentTypes = [NSSet setWithObject:@"application/json"]; 
    [manager POST:[NSString stringWithFormat:@"http://www.yourdomainname.com/getUserList"] parameters:nil success:^(AFHTTPRequestOperation *operation, id responseObject) 
    { 

     //we will add Modal class objects of users in this array 

     usersArray=[[NSMutableArray alloc]init]; 

     //getting result dictionary from response 
     NSDictionary *resultDictinary = [responseObject objectForKey:@"result"]; 
     for (NSDictionary *userDictionary in resultDictinary) 
     { 
      //allocating new user from the dictionary 
      User *newUSer=[[User alloc]initWithDictionary:userDictionary]; 
      [usersArray addObject:newUSer]; 
     } 

     //in users array, you have objects of User class 

     //reload your tableview data 
     [self.TableView reloadData]; 


    } failure:^(AFHTTPRequestOperation *operation, NSError *error) { 
     NSLog(@"Error: %@", error); 
    }]; 

}

现在创建一个名为 '用户' 的新文件
在User.m
＃进口 “User.h” User.h

@interface User : NSObject 
{ 
    NSString *userID; 
    NSString *firstName; 
    NSString *lastName; 

} 
@property (nonatomic, retain)NSString *userID; 
@property (nonatomic, retain)NSString *firstName; 
@property (nonatomic, retain)NSString *lastName; 

-(id)initWithDictionary:(NSDictionary *)sourceDictionary; 


@end

@implementation User 
@synthesize userID,firstName,lastName; 


-(id)initWithDictionary:(NSDictionary *)sourceDictionary 
{ 
    self = [super init]; 
    if (self != nil) 
    { 
     self.firstName=[sourceDictionary valueForKey:@"firstName"]; 
     self.lastName=[sourceDictionary valueForKey:@"lastName"]; 
     self.userID=[sourceDictionary valueForKey:@"userID"]; 
    } 
    return self; 

} 
@end

你numberOfRowsInSection方法
return usersArray.count;

在cellForRowAtIndexPath方法

User *user=(User *)[usersArray objectAtIndex:indexPath.row]; 
yourLabel.text=user.firstName;
