iOS中NSJSONSerialization的使用小记

     初接触的Json解析就是这个，因为觉得简单好用，解析效率还高，所以要进行Json数据解析，NSJSONSerialization真的是不二之选，下面简单的附上我的代码吧~

    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);

现在img数组里的存放的就是我的图片url了~~简单吧~就几行代码
