Code Implementation case for solving the problem of sticking packets between iPhone clients and servers

IPhone ClientAndServerThe implementation case of inter-stick packet problem solving is described in this article. If yourIPhoneThe App mustServerWhen data is exchanged, the server may encounter a situation where two messages are sent consecutively: The first message is received accurately, but the second message is not completely received. You can try the Code provided in this post on the CocoaChina forum to solve the problem of sticking packets between the iPhone client and the server.

// Save the traffic size of the last 10 network packets
  
  
M_RecvByte.AddToTail (m_nRecvByteCount );

M_RecvByte.Remove (0 );
