swift 跳到系统设置界面

首先需要设置一下：

跳转到系统的设置页主页, 在iOS8.0的时候, Apple出了这么个玩意UIApplicationOpenSettingsURLString, 可以跳转到系统设置主页

 let settingUrl = NSURL(string: UIApplicationOpenSettingsURLString)! if UIApplication.sharedApplication().canOpenURL(settingUrl)  {         UIApplication.sharedApplication().openURL(settingUrl) }

跳转到其他设置页(以下皆copy自Stack OverFlow), 只需要修改上面代码的目标URL即可

例如

About — prefs:root=General&path=About  Accessibility — prefs:root=General&path=ACCESSIBILITY  Airplane Mode On — prefs:root=AIRPLANE_MODE  Auto-Lock — prefs:root=General&path=AUTOLOCK  Brightness — prefs:root=Brightness  Bluetooth — prefs:root=General&path=Bluetooth  Date & Time — prefs:root=General&path=DATE_AND_TIME  FaceTime — prefs:root=FACETIME  General — prefs:root=General  Keyboard — prefs:root=General&path=Keyboard  iCloud — prefs:root=CASTLE  iCloud Storage & Backup — prefs:root=CASTLE&path=STORAGE_AND_BACKUP  International — prefs:root=General&path=INTERNATIONAL  Location Services — prefs:root=LOCATION_SERVICES  Music — prefs:root=MUSIC  Music Equalizer — prefs:root=MUSIC&path=EQ  Music Volume Limit — prefs:root=MUSIC&path=VolumeLimit  Network — prefs:root=General&path=Network  Nike + iPod — prefs:root=NIKE_PLUS_IPOD  Notes — prefs:root=NOTES  Notification — prefs:root=NOTIFICATIONS_ID  Phone — prefs:root=Phone  Photos — prefs:root=Photos  Profile — prefs:root=General&path=ManagedConfigurationList  Reset — prefs:root=General&path=Reset  Safari — prefs:root=Safari  Siri — prefs:root=General&path=Assistant  Sounds — prefs:root=Sounds  Software Update — prefs:root=General&path=SOFTWARE_UPDATE_LINK  Store — prefs:root=STORE  Twitter — prefs:root=TWITTER  Usage — prefs:root=General&path=USAGE  VPN — prefs:root=General&path=Network/VPN  Wallpaper — prefs:root=Wallpaper  Wi-Fi — prefs:root=WIFI  Setting —prefs:root=INTERNET_TETHERING

尽量用真机进行测试,  模拟器很多地方你是跳不过去的...我测试了, iOS8.4(iphone5), iOS9.0(iphone6), iOS9.1(iphone5s), iOS9.2(iphone5s), 跳转都是正常的. iOS5.1到iOS7貌似是不行的, 这个我没测试, 有兴趣的同学可以试一试, 告诉我结果. 谢谢...
