Identificando el dispositivo y operando
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

Obtención de la orientación del dispositivo
UIDevice *deviceInfo = [UIDevice currentDevice];
int d = deviceInfo.orientation;
deviceInfo.orientation devuelve un valor UIDeviceOrientation que se muestra a continuación:
UIDeviceOrientationUnknown 0
UIDeviceOrientationPortrait 1
UIDeviceOrientationPortraitUpsideDown 2
UIDeviceOrientationLandscapeLeft 3
UIDeviceOrientationLandscapeRight 4
UIDeviceOrientationFaceUp 5
UIDeviceOrientationFaceDown 6
Escuchando los cambios de orientación del dispositivo en un controlador de vista:
- (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
}
Para desactivar la verificación de cualquier cambio de orientación:
- (void)viewWillDisappear:(BOOL)animated {
[super viewWillDisappear:animated];
[[UIDevice currentDevice] endGeneratingDeviceOrientationNotifications];
}
Obtención del estado de la batería 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");
}
}
Usando el sensor de proximidad
//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.");
}
}
