如何侦听用户授予或拒绝免打扰权限？

<uses-permission android:name="android.permission.ACCESS_NOTIFICATION_POLICY" />

NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
if (notificationManager.isNotificationPolicyAccessGranted()) {
    // 用户已授予免打扰权限
} else {
    // 用户未授予免打扰权限
}

Intent intent = new Intent(Settings.ACTION_NOTIFICATION_POLICY_ACCESS_SETTINGS);
startActivity(intent);

UNUserNotificationCenter.current().getNotificationSettings { settings in
    if settings.authorizationStatus == .authorized {
        // 用户已授予免打扰权限
    } else {
        // 用户未授予免打扰权限
    }
}

if let settingsUrl = URL(string: UIApplication.openSettingsURLString) {
    UIApplication.shared.open(settingsUrl)
}
