                                                       error:&err];
NSString *resSrt = [[NSString alloc]initWithData:responseData encoding:NSASCIIStringEncoding];

//This is for Response
 NSLog(@"got response==%@", resSrt);
if (json)
{
NSArray *results = [json valueForKey:@"NAME"];


}


if(resSrt)
{
    NSLog(@"got response");

}

no need of this

 NSString *resSrt = [[NSString alloc]initWithData:responseData encoding:NSASCIIStringEncoding];

//This is for Response
 NSLog(@"got response==%@", resSrt);
if (json)
{
NSArray *results = [json valueForKey:@"NAME"];
}


if(resSrt)
{
NSLog(@"got response");

}

else
{
NSLog(@"faield to connect");
}

Simpley Do this

NSArray *json = [NSJSONSerialization JSONObjectWithData:responseData
                                                     options:kNilOptions
                                                       error:&err];
if (json.count>0) {
    self.txtName.text =json[0][@"NAME"];
     self.txtClass.text =json[0][@"CLASS"];
     self.txtSection.text =json[0][@"SECTION"];

    NSData* data = [json[0][@"IMAGE"] dataUsingEncoding:NSUTF8StringEncoding];

     self.imgBig.image= [UIImage imageWithData:data];

}

To parse the json try to use below code

-(void)convertJson : (NSString *)resSrt
{
    NSArray *jsonObjectAry = [NSJSONSerialization JSONObjectWithData:[resSrt dataUsingEncoding:NSUTF8StringEncoding]
                                                          options:0 error:NULL];
         if (jsonObjectAry)
       NSLog(@"Name=>%@",jsonObjectAry[0][@"NAME"]);

}

why you increase the memory, check once O/p it is sngle array – Anbu.Karthik Aug 29 '16 at 12:51
If its a single object , why server send as array. I assumed , there may possible to get list of objects . And am just shared a peace of code. user can optimize what they want. FYI: If server send empty array, "0th index will be null". – Mohanraj S K Aug 29 '16 at 13:00

A good way to handle all these son values is to use a third party like SwiftyJSON

You don't have to write lengthy methods to parse these values. Also it handles the case where the value is nil.

let json = JSON(data: dataFromNetworking)
if let userName = json[0]["user"]["name"].string {
  //Now you got your value
}

Reference: SwiftyJSON.

@TejaNandamuri: there are similar libraries available for ObjectiveC as well. – Shobhit C Aug 29 '16 at 13:01
OP main problem is to get the bitCode in the json and convert it into image. YOur answer doesn't state anything related to that. – Teja Nandamuri Aug 29 '16 at 13:02
