Java 서버가 있습니다 (iOS 클라이언트에서 요청을 올바르게 읽을 수 있습니다. 그것을 올바르게, 나는 서버에서 첫 번째 메시지 응답마다 시간을 가지고 있지만, 첫 번째 메시지)받은 후 다른 메시지를 받고 아니지만 : 대부분의 시간을 호출하지NSInputStream을 사용하는 iOS 클라이언트의 Java 서버에서 첫 번째 메시지를받은 후에 더 많은 메시지를받지 못했습니다.
Step 1-> client send login message to server
Step 2-> server validate the user and sends login info to the clients
Step 3-> Message Packet1
Message Packet2
Message Packet3
Message Packet4
step-4-> I have checked server log and it says server has send 4 string
messages
Step-5 -> On client side I am receiving only first message i.e. Message
Packet1, and there no other packets on NSInputStream showing. or NSStreamEventHasBytesAvailable option in delegate method->
- (void)stream:(NSStream *)theStream
handleEvent:(NSStreamEvent)streamEvent
이상의하지만 때로는 그것을 통신의
순서를 MessagePacket2 또는 MessagePacket4 데이터를 호출하고 가져옵니다.
제가 4 패킷 대신 4 패킷 대신 서버에서 첫 번째 패킷 만받는 이유를 알아 채지 못하게 도와주세요.
