充电时的iOS通知

Question

is possible to get notifications from an App when for exemple :

• I plug the charger?
• I am at 100% of charge?

Is it possible then to get an action to be done from this notification ?

And, last one : is it possible to have this notification even if my app is not running ? Just like I receive push notification when I get a Whatsapp message ?

thanks for your help !

You can monitor the battery's level and status with this code from Apple .

float batteryLevel = [UIDevice currentDevice].batteryLevel; //gets the battery's level
UIDeviceBatteryState currentState = [UIDevice currentDevice].batteryState; //gets the battery's status

// Register for battery level and state change notifications.
[[NSNotificationCenter defaultCenter] addObserver:self
                                         selector:@selector(batteryLevelChanged:)
                                             name:UIDeviceBatteryLevelDidChangeNotification object:nil];

[[NSNotificationCenter defaultCenter] addObserver:self
                                         selector:@selector(batteryStateChanged:)
                                             name:UIDeviceBatteryStateDidChangeNotification object:nil];

You can use those notifications to trigger whatever event you want (like local notifications).
However, you won't be able to monitor anything if your app is not running (either in the foreground or the background).
