使用SBJson將值賦給json響應

Question

我想爲響應添加值。但響應的格式如下

{ 
    "participants": [ 
        { 
         "lat_long": "0.0,0.0", 
         "name": "alma" 
        } 
        ], 
    "lat_long": "0.0,0.0", 
    "_id": "52a80a5dccb8137326000027" 
    } 

我如何添加值的鍵名& lat_long。我正在使用Sbjson方法。

在此先感謝。

Answer 1

NSURL * url=[NSURL URLWithString:@"Give your URL Here"]; 

    NSData * data=[NSData dataWithContentsOfURL:url]; 

    NSError * error; 

    NSMutableDictionary * jsonDic=[NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingMutableLeaves error:&error]; 


    NSLog(@"%@",jsonDic); 


    NSMutableArray * jsonArray=jsonDic[@"participants"]; 

    NSLog(@"%@",jsonArray); 

    NSString * str =[jsonArray valueForKey:@"lat_long"]; 


    NSString * str1 =[jsonArray valueForKey:@"name"]; 

    NSLog(@"%@",str); 

    NSLog(@"%@",str1); 

試試看看這個代碼。

我不確定，你在問什麼，但這可以幫助你獲得Disctionary的關鍵。

NSDictionary *json = [NSJSONSerialization .....//Parsed JSon 
    NSMutableDictionary *arrCopy = [json mutableCopy]; 

    NSArray *keys= [json allKeys]; 
    for (NSString *keysV in keys){ 
     NSLog(@"Keys are %@", keysV); 
     if ([keysV isEqualToString:@"_id"]) { 
      [arrCopy setValue:@"121213211323" forKey:keysV]; 
     }else if(){ 

     }....................... 
     } 
    NSLog(@"After Value added: %@", arrCopy);
