Parametry

własność Opis
Nazwa Nazwa identyfikująca urządzenie.
systemName: String Nazwa systemu operacyjnego działającego na urządzeniu reprezentowanym przez odbiornik.
model: String Model urządzenia.
systemVersion: String Aktualna wersja systemu operacyjnego.

Uwagi

Klasa UIDevice zapewnia instancję Singleton reprezentującą bieżące urządzenie. Z tego wystąpienia można uzyskać informacje o urządzeniu, takie jak przypisana nazwa, model urządzenia oraz nazwa i wersja systemu operacyjnego.

Uzyskiwanie statusu baterii i poziomu baterii

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)

    // Stuff...
}

func batteryStateDidChange(notification: NSNotification){
    // The stage did change: plugged, unplugged, full charge...
}

func batteryLevelDidChange(notification: NSNotification){
    
    let batteryLevel = UIDevice.current.batteryLevel
    if batteryLevel < 0.0 {
        print(" -1.0 means battery state is UIDeviceBatteryStateUnknown")
        return
    }
    
    print("Battery Level : \(batteryLevel * 100)%")
    // The battery's level did change (98%, 99%, ...)
}

Identyfikacja urządzenia i działanie

 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

Uzyskiwanie orientacji urządzenia

UIDevice *deviceInfo = [UIDevice currentDevice];
int d = deviceInfo.orientation;

deviceInfo.orientation zwraca wartość UIDeviceOrientation, która jest pokazana poniżej:

UIDeviceOrientationUnknown 0
UIDeviceOrientationPortrait 1
UIDeviceOrientationPortraitUpsideDown 2
UIDeviceOrientationLandscapeLeft 3
UIDeviceOrientationLandscapeRight 4
UIDeviceOrientationFaceUp 5
UIDeviceOrientationFaceDown 6

Słuchanie zmian orientacji urządzenia w kontrolerze widoku:

- (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
}

Aby wyłączyć sprawdzanie zmiany orientacji:

- (void)viewWillDisappear:(BOOL)animated {
    [super viewWillDisappear:animated];
    [[UIDevice currentDevice] endGeneratingDeviceOrientationNotifications];
}

Sprawdzanie stanu baterii urządzenia

//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");
    }
}

Korzystanie z czujnika zbliżeniowego

//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.");
    }
}
