The socket option to set that restriction is not public. If you are trying to avoid any cellular traffic, you would also need a way to avoid sending DNS over cellular. That functionality is also not public.
I did notice the following documentation on developer.apple.com: https://developer.apple.com/library/ios/documentation/CoreFoundation/Reference/CFSocketStreamRef/index.html If you can use a CFSocketStream to establish the connection, you could use kCFStreamPropertySocketNativeHandle to fetch the file descriptor out. POSIX/BSD socket APIs won’t trigger cellular to dial or VPNs to come up among other problems. -josh > On Dec 8, 2014, at 1:33 PM, Jens Alfke <j...@mooseyard.com> wrote: > > I need to (optionally) prevent a TCP socket from being opened over a cellular > connection.
