  <pre><code>- (void)willActivate {
  
      [super willActivate];
      soundAlert = [NSTimer scheduledTimerWithTimeInterval:1.2f target:self selector:@selector(SoundAlertNotification) userInfo:nil repeats:YES];
  }
  
  - (void)SoundAlertNotification
  {
      if (!isRechableFlag) {
          [self playsound];
      }
  
  }
  
  #pragma mark - Play Sound Methods -
  
  - (void) playsound
  {
      [[WKInterfaceDevice currentDevice] playHaptic:WKHapticTypeRetry];
