It looks like you're approaching the problem from the wrong side.
You should handle this new view poping up in when the correct (
kCFSocketConnectCallBack) type ofCFSocketCallBackis invoked. Or possibly setting a flag there and handling view from main code.You can have a
BOOLflag calledpopUpNConnectedViewthat is initialized toNO.You set it to
YESinconnectCallBackmethod. When your main loop sees it (at connection-oriented applications ther's usually some kind of a haertbeat timer) it pops up the view and clears the flag.You didn't post any code so it's impossible to give you a more direct answer - you'll definetly find your answer here:
