Opening the Settings app from another app

Question

Okay  I know that there are many question about it  but they are all from many time ago   So  I know that it is possible because the Map app does it   In the Map app if I turn off the localization for this app  it send me a message  and if I press okay  the  Settings App  will be open  And my question is  how is this possible  How can I open the  Setting app  from my own app   Basically I need to do the same thing  if the user turn off the location for my app  then I ll show him a message saying something that will open the  Setting app

Swift 4  I prefer to open setting in a safer way   if let settingUrl   URL string UIApplicationOpenSettingsURLString         UIApplication shared open settingUrl    else       print  Setting URL invalid

UIApplicationOpenSettingsURLString this will only work if you have previously allowed for any permission  For example Location  Photo  Contact  Push notification access  So if you have not such permission s  from the user   If iOS 10 or above   It will open the Settings but then crash it  The reason  there s nothing in settings for your app   Below code will open your application settings inside the iOS Setting   NSURL  url    NSURL URLWithString UIApplicationOpenSettingsURLString   if    UIApplication sharedApplication  canOpenURL url           UIApplication sharedApplication  openURL url       Due to device unavailability  I couldn t check this on iOS  lt  10   Also  I could find below code from some gist and it works fine on iOS 10 as well  But I am not sure if this will approve by Apple review team or not   https   gist github com johnny77221 bcaa5384a242b64bfd0b8a715f48e69f

From  Yatheeshaless s answer   You can open settings app programmatically in iOS8  but not in earlier versions of iOS   Swift      UIApplication sharedApplication   openURL NSURL string UIApplicationOpenSettingsURLString      Swift 4   if let url   NSURL string  UIApplicationOpenSettingsURLString  as URL        UIApplication shared openURL url      Swift 4 2  BETA    if let url   NSURL string  UIApplication openSettingsURLString  as URL        UIApplication shared open url  options       completionHandler  nil      Objective-C     UIApplication sharedApplication  openURL  NSURL URLWithString UIApplicationOpenSettingsURLString

YES   you can launch Device Settings screen  I have tested on iOS 9 2  Step 1  we need to add URL schemes  Go to Project settings --  Info --  URL Types --  Add New URL Schemes    Step 2  Launch Settings programmatically Thanks to  davidcann    UIApplication sharedApplication  openURL  NSURL URLWithString   prefs          Also we can launch sub-screens like Music  Location etc  as well by just using proper name    UIApplication sharedApplication  openURL  NSURL URLWithString   prefs root MUSIC       See this full name list here shared by Henri Normak    Update   As per the comment everyone wants to know what happens after this change to my application submission status   So YES   I got successful update submission and application is available on store without any complain   Just to confirm  I Just downloaded this morning and disabled Location services  and then started the app  which asked me for location permission and then my alert popup was there to send me on settings -  location services page --  Enabled --  That s it      NOTICE  Your app might be rejected     even if it s approved it can be rejected in future version if you use this method    4

In Swift 3 all I needed is this  here for example redirect to my app notifications     if let url   URL string   App-Prefs root NOTIFICATIONS ID amp path your app bundleID         if  available iOS 10 0               UIApplication shared open url  completionHandler   none        else              Fallback on earlier versions           Source  phynet gist   This worked with me only when settings is in background  It will redirect you to your app notification settings but if settings wasn t running in the background it will just redirect you to notification settings in general

To add to accepted answer   from apple developer documentation   When you open the URL built from this string  openSettingsURLString   the system launches the Settings app and displays the app   s custom settings  if it has any   So  if you want to open settings for your app  create your own Settings bundle

Seems like you can use the prefs  lt area gt  URL to open the settings and go to specific areas  Apple could change these and break your app so always check if you can open them first   From this
