It's hard to say what's going on here with the details you've provided (for
example, what sort of error do you get when replication fails) but the last
part of the quote above piqued my interest. Are you trying to build a URL from
a resolved service? If so, I recommend that you avoid the "addresses" array
entirely and simply put the host name from the service into the URL. Here's a
snippet of code that does this for an _http._tcp. service.
- (NSURL *)URLForService:(NSNetService *)service {
NSDictionary * TXTRecordDictionary;
NSURLComponents * urlComponents;
NSNumber * portObj;
NSInteger port;
NSURL * url;
assert(service != nil);
// Get the port, defaulting to port 80.
portObj = nil;
port = [service port];
if ( (port != 0) && (port != 80) ) {
portObj = @(port);
}
// Build a set of URL components, using some default values, some values
// calculated above and some values directly from the service.
urlComponents = [[NSURLComponents alloc] init];
urlComponents.scheme = @"http";
urlComponents.host = [service hostName];
urlComponents.port = portObj;
// Create a URL form the components and return it.
url = [urlComponents URL];
assert(url != nil);
return url;
}
The advantage of this is that it pushes off the question of address selection
until connect time, and your connect-time code is better placed to decide which
address to use.
Share and Enjoy
