Would the following be considered as private API use? After googling I have found many conflicting reports.
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"prefs://"]];
Also does anyone have a list of valid urls within the settings application? For example:
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"prefs://notifications"]];
will open the notifications page of the settings application.
I have found the answer to my own question.
It is supported in iOS5. URL Schemes can be found here: http://maniacdev.com/2011/11/tutorial-using-url-schemes-to-open-the-settings-app-to-a-specific-page-in-ios-5/
