macOS上是否有相当于kIOPSCurrentCapacityKey的电池电量did更改通知？

import Foundation

// 获取电池电量
func getBatteryLevel() -> Float {
    let powerManager = NSPowerManager.shared
    return powerManager.currentCapacity
}

// 监听电量变化
func observeBatteryLevel() {
    NotificationCenter.default.addObserver(forName: NSNotification.Name.NSPowerStateDidChange, object: nil, queue: nil) { notification in
        let batteryLevel = getBatteryLevel()
        print("Battery level changed: \(batteryLevel)")
    }
}

// 示例用法
let batteryLevel = getBatteryLevel()
print("Current battery level: \(batteryLevel)")

observeBatteryLevel()
