ios - Apple watch app does not work when iPhone app is in terminated state? -


i working on apple watch app, facing weird issue, i.e. watch app works when manually open iphone app or when iphone app in background. when terminate iphone app , test apple watch app not work more.

here mentioning watch app flow:

  • when apple watch app starts, call web api fetch response server.
  • i used openparentapplication:reply: method call web api parent app
  • i understand that, have call web api method in background thread because, openparentapplication:reply: method automatically open parent app in iphone , suspends in mean time, if processing time taking task using method should use background thread mentioned under watchkit development tips. using background thread call web api.
  • when response pass watch app.

here attached snippet:

watch app - initialinterfacecontroller.m

- (void)awakewithcontext:(id)context {     [super awakewithcontext:context]; }  - (void)willactivate {     [super willactivate];     [self getdetails]; }   - (void)getdetails{     //open parent app     [wkinterfacecontroller openparentapplication:@{@“request”:@“details”}                                            reply:^(nsdictionary *replyinfo, nserror *error) {                                                if (!error) {                                                    nslog(@“success”);                                                    [self parsekpi:replyinfo];                                                }                                                else{                                                    nslog(@"error - %@", error.localizeddescription);                                                }                                            }];  }

iphone app - appdelegate.m

iphone app - apihandler.m

but approach not working me.

i found 1 more issue in watch app simulator i.e. - (void)awakewithcontext:(id)context initial view controller called, - (void)willactivate method not being called , see watch app spinner. times works. it’s quite strange. have around 15 controls (including groups) in initial interface controller added using storyboard.

i have referred watchkit not calling willactivate method , modified code still facing same issue.

can 1 let me know why issue persisting in app?

you'll need handle request in iphone app bit differently in order app not killed off os. i've shared similar answer here: https://stackoverflow.com/a/29848521/3704092
