Request: Ability to determine if stream is active

[nst]

Sure, but I need more information. What do you mean exactly by an "active" stream? Can you give an example?

[inb4ohnoes]

Ok. For example the getUserStreamDelimited method may or may not be active after the app (iOS) has been revived from background. If the stream is active, then there's no need to call the rest method to backfill tweets, but if it's not active one would backfill tweets and revive the stream connection. Do you see what I mean?

[nst]

Yes I do, thank you for explaining. The naive way to deal with this situation would be cancelling and reconnecting to the stream each time the app becomes active. It is ok for you or do you need something more sophisticated?

[inb4ohnoes]

I would indeed prefer something more sophisticated since users tend to multitask around a lot. I'd prefer not to disconnect and reconnect every six times they do so in a minute.

[nst]

You're right. So, I think you should detect lost connections in the error block and restart the request in this case only.

// ...
} errorBlock:^(NSError *error) {

    if([[error domain] isEqualToString:NSURLErrorDomain] && [error code] == NSURLErrorNetworkConnectionLost) {
        [self startStreamRequest];
    }

}];

I'm not sure we should add something specific into STTwitter, what do you think?

[inb4ohnoes]

Hmm that's a good suggestion. I'll look into doing it this way. Thanks!

BTW, How to cancel the stream? Also, i wonder if there is any way to disable sending friend list every time the stream gets connected since it would be lots of overheads if we "cancelling and reconnecting to the stream each time the app becomes active:

Thanks,
James

Make an STHTTPRequest object somewhere like your session manager and such. When you initialize the stream, set the stream to your object like so:

_userStream = [api getUserStreamDelimited:...

When you need to disconnect the stream, simply [_userStream cancel]. To reconnect, simply reinitialize it again like above. It's that easy! Thanks @nst for making such an easy to use library.

Also, the friends list is received every single time you start the stream. There's no way to disable it as far as I know.
