I've had trouble finding simple guides/examples for basic sockets in Objective-C (using NSSocketPort with NSFileHandle or using CFSocket/CSNetwork). Can anyone 开发者_如何学JAVArecommend a guide or a useful example? I would appreciate this greatly! I have tried to use this, but it is incomplete. Thanks!
P.S. I have been stuck in this part of my project for awhile and am starting to get desperate for some help.
I know I am submitting answer to an very old question. In case you(visitor/stackoverflow {lover/users}) want to code your own asynchronous socket. All you need to do is detach native socket handle from connected CFSocketRef object.
void TCPClientCallBackHandler(CFSocketRef s, CFSocketCallBackType callbacktype,CFDataRef address, const void *data,void *info){
ClientSocket *obj_client_ptr=(__bridge ClientSocket*)info;
switch (callbacktype) {
case kCFSocketConnectCallBack :
if(data){
[obj_client_ptr StopClient];
}
else{ //detach socket started
CFSocketNativeHandle handle=CFSocketGetNative(s);
CFSocketSetSocketFlags(s, 0);
CFSocketInvalidate(s);
CFRelease(s);
s=nil;//detach socket ended
[obj_client_ptr ConfigureStream:handle];
// handle pass to CFStreamCreatePairWithSocket then bridge to NSStream
}
break;
}
}
if still not got it, then watch it on youtube: https://www.youtube.com/watch?v=bJP4nysTmnI
The easiest way I've found to do this is the Cocoa Async Socket class:
https://github.com/robbiehanson/CocoaAsyncSocket
It's pretty straight forward to use, there's good html documentation included.
