使用App-Prefs做域跳转，代码如下：
if let url = URL(string: "App-Prefs:root=NOTIFICATIONS_ID"), UIApplication.shared.canOpenURL(url) {
UIApplication.shared.open(url, options: [:], completionHandler: nil)
}
类似的域还有：
App-Prefs:root=WIFI App-Prefs:root=Bluetooth App-Prefs:root=MOBILE_DATA_SETTINGS_ID App-Prefs:root=INTERNET_TETHERING App-Prefs:root=Carrier App-Prefs:root=NOTIFICATIONS_ID App-Prefs:root=General App-Prefs:root=General&path=About App-Prefs:root=General&path=Keyboard App-Prefs:root=Wallpaper App-Prefs:root=SIRI App-Prefs:root=Privacy App-Prefs:root=SAFARI App-Prefs:root=MUSIC App-Prefs:root=MUSIC&path=com.apple.Music:EQ App-Prefs:root=Photos
