我想知道TCP如何实现按顺序交付.

让我们说这是事件列表

1. packet1发送,ack收到.
2. packet2发送,ack未收到.
3. packet3发送.
4. packet4发送.
5. ack4收到了.
6. ack3收到了.
7. ack2收到了.

你能告诉我顺序发生了什么吗？

如何在 Python 中使用字节数组播放声音。更准确地说，我从套接字读取了一个字节数组，我想将其转换为声音以理解它。我怎样才能做到这一点？

任何图书馆都会很有用。

我知道这是非常基本的,但无法调试问题.这是我的Podfile.

source 'https://github.com/CocoaPods/Specs.git'
platform :ios, '8.1'
pod 'GoogleMaps'

我从这里选了这个.当我尝试时pod install,我明白了
