HomeKit - How to update accessory isReachable value, when i come back from background to foreground?












3















Situation: i am developing an app, which manages HomeKit accessories. For example i do that:




  1. Accessory is power on, and i see it via app. Also in foreground mode HMAccessoryDelegate method:


func accessoryDidUpdateReachability(HMAccessory)



works fine and i can handle status of my accessory.




  1. I switch app to background mode.


  2. I turn off accessory (i mean completely power off) so it must be unreachable.


  3. I switch app to foreground mode, but accessory is still reachable.
    method func accessoryDidUpdateReachability(HMAccessory) — not called.
    value accessory.isReachable not updated.



Example of code when i go to foreground:



func applicationDidBecomeActive(_ application: UIApplication) {  
if let home = HomeStore.sharedStore.home {
for accessory in home.accessories {
print(accessory.isReachable) //not updated
for service in accessory.services {
for characteristic in service.characteristics {
characteristic.readValue { (error) in //updated
if error == nil {
let notification = Notification(name: Notification.Name(rawValue: "UpdatedCharacteristic"))
NotificationCenter.default.post(notification)
}
}
}
}
}
}
}


Question: how to update isReachable values of accessories, when i come back from background mode to foreground?

          You can create a function in the ViewController that implements HMHomeManagerDelegate:



          func startHomeManager() {
          manager = HMHomeManager()
          manager.delegate = self

          // do something here
          }


          and add a call to startHomeManager() to your viewDidLoad(). That will refresh your HMHome object. Then call this func in your AppDelegate:



          func applicationWillEnterForeground(_ application: UIApplication) {
          viewController.startHomeManager()
          viewController.didRestartHomeManager()
          }


          A bonus is that you can call startHomeManager() for pull to refresh, etc.
