检测充电设备是否正常

您最好使用:

[[UIDevice currentDevice] setBatteryMonitoringEnabled:YES];

if ([[UIDevice currentDevice] batteryState] != UIDeviceBatteryStateUnplugged) {
      [UIApplication sharedApplication].idleTimerDisabled=YES;
    }

这是因为你必须关心你自己 二 不同的状态-一个是电池处于 ,另一个是 充满电 .

如果你 真正地

是的,UIDevice能够告诉您:

[[UIDevice currentDevice] setBatteryMonitoringEnabled:YES];

if ([[UIDevice currentDevice] batteryState] == UIDeviceBatteryStateCharging) {
    NSLog(@"Device is charging.");
}

见 UIDevice

斯威夫特4

UIDevice.current.isBatteryMonitoringEnabled = true

if (UIDevice.current.batteryState != .unplugged) {
    print("Device is charging.")
}

斯威夫特3

UIDevice.currentDevice().batteryMonitoringEnabled = true;

if (UIDevice.currentDevice().batteryState != .Unplugged) {
    print("Device is charging.");
}

Swift 3:

UIDevice.current.isBatteryMonitoringEnabled = true
let state = UIDevice.current.batteryState

if state == .charging || state == .full {
    print("Device plugged in.")
}

你可以用 darwin notification center 并使用事件名称 com.apple.springboard.fullycharged .

通过这种方式,您将收到自定义方法的通知,下面是一个代码剪报:

// Registering for a specific notification
NSString *notificationName = @"com.apple.springboard.fullycharged";
CFNotificationCenterAddObserver(CFNotificationCenterGetDarwinNotifyCenter(),
                                NULL,
                                yourCustomMethod,
                                (__bridge CFStringRef)notificationName,
                                NULL, 
                                CFNotificationSuspensionBehaviorDeliverImmediately);

// The custom method that will receive the notification
static void yourCustomMethod(CFNotificationCenterRef center, void *observer, CFStringRef name, const void *object, CFDictionaryRef userInfo)
{
  NSString *nameOfNotification = (__bridge NSString*)name;

  if([nameOfNotification isEqualToString:notificationName])
  {
    // Do whatever you want...
  }
} 

Swift 4.2

布尔值

    var batteryState: Bool {
        IDevice.current.isBatteryMonitoringEnabled = true
        let state = UIDevice.current.batteryState

        if state == .charging || state == .full {
            print("Device plugged in.")
            return true

        } else {
            return false
        }

    }

func checkForCharging() {

UIDevice.current.isBatteryMonitoringEnabled = true

if UIDevice.current.batteryState != .unplugged {

print("Batery is charging")

} else if UIDevice.current.batteryState == .unplugged {

print("Check the cable")

}

如果你想查看不止一个地方,而不是像这样的地方。

class Device {

    static let shared = Device()

    func checkIfOnCharcher() -> Bool {
        UIDevice.current.isBatteryMonitoringEnabled = true
        if (UIDevice.current.batteryState != .unplugged) {
            return true
        } else {
            return false
        }
    }
}

用法:

if Device.shared.checkIfOnCharcher() == true { 
      //Some Code
} else { 
   // Some code
}

... 和@Brad的答案 :

    UIDevice.current.isBatteryMonitoringEnabled = true
    if UIDevice.current.batteryState != .unplugged {
        UIApplication.shared.isIdleTimerDisabled = true
    }

UIDevice.current.batteryState

但您可以更进一步,使用通知中心查看状态何时更改。

下面是一个示例,说明当应用程序插入时,如果您希望屏幕保持清醒:

斯威夫特5

    class BatteryManager {
        static let shared: BatteryManager = .init()

        private init() {
            UIDevice.current.isBatteryMonitoringEnabled = true
    
            NotificationCenter.default.addObserver(
                self,
                selector: #selector(batteryStateDidChange),
                name: UIDevice.batteryStateDidChangeNotification,
                object: nil
            )
        }
    
        deinit {    
            NotificationCenter.default.removeObserver(
                self,
                name: UIDevice.batteryStateDidChangeNotification,
                object: nil
            )
        }
    
        @objc private func batteryStateDidChange() {
            let state = UIDevice.current.batteryState
    
            UIApplication.shared.isIdleTimerDisabled = state == .full || state == .charging
        }
    }
