Answer 1

 NSString *responseString = [request1 responseString];//your json response will be here
 NSMutableDictinoary *dataDict = [[[responseString JSONValue] valueForKey:@"DAATA"]mutableCopy];//take response in dictinoary
 for(int i = 0 ; i<[[dataDict valueForKey:@"DAATA"] count];i++)
{
    if([[[[dataDict valueForKey:@"DAATA"] objectAtIndex:i] valueForKey:@"Image_Id"] isEqualToString:@"court"])//get what you want here for example get "Image_Id"
    {
        NSMutableDictionary *dd=[[dataDict valueForKey:@"result"] objectAtIndex:i];
        [arrCourt addObject:dd];
    }
   and so on.........

Answer 2

NSJSONSerializationを確認し、それを使用してjson文字列を解析します。

Answer 3

もう1つの方法は、SBJsonライブラリを使用することです。

- (void) connectionDidFinishLoading:(NSURLConnection *) conn 
{
//Call back called when data reception completes (stored in variable data)
NSString *jsonString = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
NSDictionary *results = [jsonString JSONValue]; // This is a new category added to the NSString by SBJSON
if ([results count]>0)
{ 
    // decoding a JSON object like so: {"result":"yes"}
    [results objectForKey:@"result"] ;
    if ([[results objectForKey:@"result"] isEqualToString:@"yes"])
    {
        [self registrationStateSetTo:YES];
        NSLog(@" registered OK "); 
    }
    else 
    {
        [self registrationStateSetTo:NO];
        NSLog(@" registration failed "); 
    }
}
}
