代码部分:

            //是否安装QQ
            if([[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:@"mqq://"]])
            {
                 //用来接收临时消息的客服QQ号码(注意此QQ号需开通QQ推广功能,否则陌生人向他发送消息会失败)
                 NSString *QQ = @"1099779883";
                 //调用QQ客户端,发起QQ临时会话
                 NSString *url = [NSString stringWithFormat:@"mqq://im/chat?chat_type=wpa&uin=%@&version=1&src_type=web",QQ];
                 [[UIApplication sharedApplication] openURL:[NSURL URLWithString:url]];
            }
