Tutorial: Using URL Schemes To Open The Settings App To A Specific Page In iOS 5
Something that I saw mentioned back when the iOS 5 sdk was in beta was that you could use custom URL schemes to open the settings app up to a specific page.
While this capability has carried over to the iOS 5 release this capability appears to still be undocumented by Apple.
Alex Curylo has created a useful little writeup on using these URL schemes for location services, twitter, and bluetooth settings:
Turn on Location Services?
[NSURL URLWithString:@”prefs:root=LOCATION_SERVICES”]];
Set up Twitter?
[NSURL URLWithString:@”prefs:root=TWITTER”]];
Hook up a Bluetooth device?
[NSURL URLWithString:@”prefs:root=General&path=Bluetooth”]];
And one commenter on Alex’s site also mentioned how to do it for your own app:
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@”prefs:root=Apps&path=Your+App+Display+Name”]];
The url schemes also work just fine when linked in HTML for those browsing on their iOS devices.
