Open system settings via app (location rights, camera permissions, etc.)

Method One:

Nsurl *url = [Nsurl urlwithstring:uiapplicationopensettingsurlstring];

url = [Nsurl urlwithstring:uiapplicationopensettingsurlstring];

if ([[[UIApplication sharedapplication] Canopenurl:url]) {

[[UIApplication sharedapplication] openurl:url];

}

which

Uiapplicationopensettingsurlstring is a string, defined in the application file, with a number of static strings that open other settings pages, such as positioning settings, and so on.

Method Two:

Nsurl*url=[nsurl urlwithstring:@ "Prefs:root=location_services"]; Positioning settings for
[[UIApplication sharedapplication] openurl:url];
