Close/Deactivate WCSession

Question

I am developing an iPhone app (iOS 9 beta) with watch extension (watchOS 2), and to pass the data from watch to phone I am using WCSession.

I have 2 different view controllers using WCSessions, so for each of the controller I am instantiating new WCSession object. For the first view controller it works fine, but when I want to receive messages in second view controller, few initial messages are still being sent to first controller.

Is there any way I can deactivate / disable session of first view controller before going to second controller? Or are there any other options I should look into?

Thanks!

What kind of WC messages are you sending? InstantMessage? ApplicationData? — Philip, Jul 20 '15 at 10:57
To people from future: the constructor of `WCSession` is now private as in Watch OS 2 release. — Jokester, Oct 08 '15 at 07:32

When you are passing data back and forth you are sending Dictionaries. If you specify good keys you could get the appropriate data for each ViewController.

Example:

ViewController1:

[session updateApplicationContext:@{@"viewController1": @"item1"} error:&error];

ViewController2:

[session updateApplicationContext:@{@"viewController2": @"item2"} error:&error];

When you are receiving data:

- (void) session:(nonnull WCSession *)session didReceiveApplicationContext:(nonnull NSDictionary<NSString *,id> *)applicationContext {

    if ([applicationContext objectForKey:@"viewController1"]) {
        //ViewController1 data
    } else if ([applicationContext objectForKey:@"viewController2"]) {
        //ViewController2 data
    }
}

I feel like this doesn't answer the question. The question was about how to deactivate the session, not how to pass data — Tyler Sheaffer, Aug 02 '16 at 20:44
This doesn't answer the question on how to deactivate or close a WCSession. — lostAtSeaJoshua, Feb 09 '17 at 22:41
