I want to send instant message to iOS app from watch app. Implemented the following code in XCode7 beta 4 version and keeping the application in foreground in both simulators. here is the code I implemented
In watchkit interfaceController
-(void)willActivate { [super willActivate]; if ([WCSession isSupported]) { WCSession *session = [WCSession defaultSession]; session.delegate = self; [session activateSession]; } } -(IBAction)buttonClicked { NSDictionary *applicationDict = [[NSDictionary alloc] initWithObjects:@[@"Hi"] forKeys:@[@"key"]]; if([[WCSession defaultSession] isReachable]) { [[WCSession defaultSession] sendMessage:applicationDict replyHandler:^(NSDictionary *reply) { NSLog(@"%@",reply); } errorHandler:^(NSError *error) { NSLog(@"%@",error); }]; } }
In iOS app class
-(void)viewDidLoad { [super viewDidLoad]; if ([WCSession isSupported]){ WCSession *session = [WCSession defaultSession]; session.delegate = self; [session activateSession]; } } -(void)session:(nonnull WCSession *)session didReceiveMessage:(nonnull NSDictionary *)message replyHandler:(nonnull void (^)(NSDictionary * __nonnull))replyHandler { dispatch_async(dispatch_get_main_queue(), ^{ self.testLbl.text = [message objectForKey:@"key"]; [self.view setNeedsDisplay]; }); }
