Hey Folks,
I'm working on a app that establishes a network connection using NSStream. I
found though that the code does not behave very well when it is trying to
connect to an unreachable IP address or an IP address that just isn't accepting
connections on the port I have specified. The code I'm using is below. Does
anybody have any good ideas on how to detect a connection timeout or a complete
connection failure? Apple's documentation indicates that if a connection
cannot be established the NSInputStream and NSOutputStream returned will be
nil, but for some reason my checks for that never seem to work. Any help is
appreciated and thanks in advance.
NSHost *host = [NSHost hostWithAddress:address];
[NSStream getStreamsToHost:host port:port inputStream:&is outputStream:&os];
if (!is || !os)
{
NSLog(@"This line doesn't execute, even with a bogus IP address");
}
buffer = [[NSMutableData alloc] initWithCapacity:0];
[is retain];
[os retain];
[is open];
[os open];
