Ottenere lo stato della batteria e il livello della batteria
override func viewDidLoad() {
super.viewDidLoad()
NotificationCenter.default.addObserver(self, selector: Selector(("batteryStateDidChange:")), name: NSNotification.Name.UIDeviceBatteryStateDidChange, object: nil)
NotificationCenter.default.addObserver(self, selector: Selector(("batteryLevelDidChange:")), name: NSNotification.Name.UIDeviceBatteryLevelDidChange, object: nil)

print(" -1.0 means battery state is UIDeviceBatteryStateUnknown")
return
}
print("Battery Level : \(batteryLevel * 100)%")
// The battery's level did change (98%, 99%, ...)
}
Identificazione del dispositivo e funzionamento
UIDevice *deviceInfo = [UIDevice currentDevice];
NSLog(@"Device Name %@", deviceInfo.name);
//Ex: myIphone6s
NSLog(@"System Name %@", deviceInfo.systemName);
//Device Name iPhone OS
NSLog(@"System Version %@", deviceInfo.systemVersion);
//System Version 9.3
NSLog(@"Model %@", deviceInfo.model);
//Model iPhone
NSLog(@"Localized Model %@", deviceInfo.localizedModel);
//Localized Model iPhone
int device=deviceInfo.userInterfaceIdiom;
//UIUserInterfaceIdiomPhone=0
//UIUserInterfaceIdiomPad=1
//UIUserInterfaceIdiomTV=2
//UIUserInterfaceIdiomCarPlay=3
//UIUserInterfaceIdiomUnspecified=-1
NSLog(@"identifierForVendor %@", deviceInfo.identifierForVendor);
//identifierForVendor <__NSConcreteUUID 0x7a10ae20> 556395DC-0EB4-4FD5-BC7E-B16F612ECC6D
Ottenere l'orientamento del dispositivo
UIDevice *deviceInfo = [UIDevice currentDevice];
int d = deviceInfo.orientation;
deviceInfo.orientation restituisce un valore UIDeviceOrientation che viene mostrato come di seguito:
UIDeviceOrientationUnknown 0
UIDeviceOrientationPortrait 1
UIDeviceOrientationPortraitUpsideDown 2
UIDeviceOrientationLandscapeLeft 3
UIDeviceOrientationLandscapeRight 4
UIDeviceOrientationFaceUp 5
UIDeviceOrientationFaceDown 6
Ascolto delle modifiche all'orientamento del dispositivo in un controller di visualizzazione:
- (void)viewWillAppear:(BOOL)animated
{
[super viewWillAppear:animated];
[[UIDevice currentDevice] beginGeneratingDeviceOrientationNotifications];
[[NSNotificationCenter defaultCenter] addObserver:self
selector:@selector(deviceOrientationDidChange)
name:UIDeviceOrientationDidChangeNotification
object:nil];
}
-(void)deviceOrientationDidChange
{
UIDeviceOrientation orientation = [[UIDevice currentDevice] orientation];
if (orientation == UIDeviceOrientationPortrait || orientation == UIDeviceOrientationPortraitUpsideDown) {
[self changedToPortrait];
} else if (orientation == UIDeviceOrientationLandscapeLeft || orientation == UIDeviceOrientationLandscapeRight) {
[self changedToLandscape];
}
-(void)changedToPortrait
{
// Function Body
}
-(void)changedToLandscape
{
// Function Body
}
Per disabilitare il controllo di eventuali cambiamenti di orientamento:
- (void)viewWillDisappear:(BOOL)animated {
[super viewWillDisappear:animated];
[[UIDevice currentDevice] endGeneratingDeviceOrientationNotifications];
}
Ottenere lo stato della batteria del dispositivo
//Get permission for Battery Monitoring
[[UIDevice currentDevice] setBatteryMonitoringEnabled:YES];
UIDevice *myDevice = [UIDevice currentDevice];
[myDevice setBatteryMonitoringEnabled:YES];
double batLeft = (float)[myDevice batteryLevel] * 100;
NSLog(@"%.f",batLeft);
int d = myDevice.batteryState;
//Returns an Integer Value
//UIDeviceBatteryStateUnknown 0
//UIDeviceBatteryStateUnplugged 1
//UIDeviceBatteryStateCharging 2
//UIDeviceBatteryStateFull 3
//Using notifications for Battery Monitoring
-(void)startMonitoringForBatteryChanges
{
// Enable monitoring of battery status
[[UIDevice currentDevice] setBatteryMonitoringEnabled:YES];
// Request to be notified when battery charge or state changes
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(checkBatteryStatus) name:UIDeviceBatteryLevelDidChangeNotification object:nil];
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(checkBatteryStatus) name:UIDeviceBatteryStateDidChangeNotification object:nil];
}
-(void) checkBatteryStatus
{
NSLog (@"Battery Level is %.f",[[UIDevice currentDevice] batteryLevel]*100);
int d=[[UIDevice currentDevice] batteryState];
if (d==0)
{
NSLog(@"Unknown");
}
else if (d==1)
{
NSLog(@"Unplugged");
}
else if (d==2)
{
NSLog(@"Charging");
}
else if (d==3)
{
NSLog(@"Battery Full");
}
}
Utilizzo del sensore di prossimità
//Enabling the proximity Sensor
- (void)viewWillAppear:(BOOL)animated {
[super viewWillAppear:animated];
[[UIDevice currentDevice] setProximityMonitoringEnabled:YES];
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(sensorStateMonitor:) name:@"UIDeviceProximityStateDidChangeNotification" object:nil];
}
- (void)sensorStateMonitor:(NSNotificationCenter *)notification
{
if ([[UIDevice currentDevice] proximityState] == YES)
{
NSLog(@"Device is close to user.");
}
else
{
NSLog(@"Device is not closer to user.");
}
}
