ios - Update Application Badge With WatchKit and Widget (Today Extension)? -

-

in app update application badge after events using code works:

[[uiapplication sharedapplication] schedulelocalnotification:localnotification];

however [uiapplication sharedapplication] cannot called watchkit or widget. there way widget update application badge other way?

i tried using background fetch this. badge gets updated when explicitly "simulate background fetch" xcode. on actual device background fetch never gets called? idea command call background fetch? 

- (void)application:(uiapplication *)application performfetchwithcompletionhandler:(void (^)(uibackgroundfetchresult))completionhandler {     // background fetch     [[globalnotifications sharedinstance] setapplicationbadge];     completionhandler(uibackgroundfetchresultnewdata); }

thanks insight on this.

you correct schedulelocalnotification can called ios main app. watch app, if using watchos 2 can tell ios app schedule notification in background using watchconnectivity. recommend using wcsession method sendmessage schedule notification.

in watchos 1, can use openparentapplication method so:

// on watch extension [interfacecontroller openparentapplication:request reply:^(nsdictionary *replyinfo, nserror *error) {     // handle response phone }];  // in appdelegate of phone: - (void)application:(uiapplication *)application handlewatchkitextensionrequest:(nsdictionary *)userinfo reply:(void (^)(nsdictionary *))reply      // todo: schedule notification here...     nsdictionary *response = // custom response     reply(response); }

i not aware of way different kind of app extension (like today extension) kind of communication parent app.
