初接觸的Json解析就是這個，因為覺得簡單好用，解析效率還高，所以要進行Json數據解析，NSJSONSerialization真的是不二之選，下面簡單的附上我的代碼吧~

    NSError *error;

    NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:@"http://192.168.1.122:8080/app/common/focus/4"]];

    NSData *response = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];

    NSArray *imgarr = [NSJSONSerialization JSONObjectWithData:response options:NSJSONReadingMutableLeaves error:&error];

    NSLog(@"%@",imgarr);

    img = [[NSMutableArray alloc]init];

    for (int i = 0; i<[imgarr count]; i++) {

        NSDictionary *imgDic = [imgarr objectAtIndex:i];

        NSString *imgstr = (NSString*)[imgDic objectForKey:@"imgsrc"];

        NSString *port = @"http://192.168.1.122:8080";//

        NSString *imgstr1 = [port stringByAppendingString:imgstr];

        [img addObject:imgstr1];

    }

    NSLog(@"%@",img);

現在img數組里的存放的就是我的圖片url了~~簡單吧~就幾行代碼
