I tried using an NSSocketPort to get a port for the NSNetService and DO,
just out of curiosity. This code creates a service that shows up in the
browse list, until I added the final assertion. So receivePort is still
valid, but the NSSocketPortNameServer returns a port that's not valid (or
maybe nil...I didn't check).
So even if there is a way to make it work by eliminating
NSSocketPortNameServer, I'd hate to say whether it worked by accident or
design, DO being what it is :).
#import <Foundation/Foundation.h>
#import <sys/socket.h>
#include <netinet/in.h>
#include <unistd.h>
int main (int argc, char const *argv[])
{
NSAutoreleasePool *pool = [NSAutoreleasePool new];
NSString *sharingName = @"DO test name";
NSPort *receivePort = [NSSocketPort port];
BOOL didRegister = [receivePort isValid] && [[NSSocketPortNameServer
sharedInstance] registerPort:receivePort name:sharingName];
NSCParameterAssert(didRegister);
int fd = [(NSSocketPort *)receivePort socket];
NSCParameterAssert(fd >= 0);
const struct sockaddr_in *saddr = [[(NSSocketPort *)receivePort address]
bytes];
uint16_t port = ntohs(saddr->sin_port);
NSLog(@"port = %d", port);
NSNetService *service = [[NSNetService alloc] initWithDomain:@""
type:@"_bdsk._tcp." name:sharingName port:port];
NSMutableDictionary *dictionary = [NSMutableDictionary
dictionaryWithCapacity:4];
[dictionary setObject:@"0" forKey:@"txtvers"];
[dictionary setObject:@"NO" forKey:@"authenticate"];
[dictionary setObject:@"dummy" forKey:@"ident"];
[service setTXTRecordData:[NSNetService
dataFromTXTRecordDictionary:dictionary]];
[service publishWithOptions:0];
NSCParameterAssert([receivePort isValid]);
NSCParameterAssert([[[NSSocketPortNameServer sharedInstance]
portForName:sharingName] isValid]);
[[NSRunLoop currentRunLoop] run];
[pool drain];
return 0;
}
