NSMutableDictionary*dataDict=[[responseString JSONValue]valueForKey:@“DAATA”]mutableCopy]//用言语回应
对于（inti=0；i另一种选择是使用库

首先写你的代码…然后我建议你。！！检查我的答案，你的值似乎已经被提取，否则你怎么能发布它们。。。？
 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.........

}
