iOS Launching Settings -> Restrictions URL Scheme

Question

I've recently discovered the awesome iOS5 custom Settings URL Scheme, which can be explained in detail at this great website.

I've found this to work, directing the user to the Settings app from my application:

[[UIApplication sharedApplication] openURL:        [NSURL URLWithString:@"prefs:root=General"]]; 

But cannot seem to route directly to the Restrictions path via the path parameter:

[[UIApplication sharedApplication] openURL:    [NSURL URLWithString:@"prefs:root=General&path=Restrictions"]]; 

Has anyone found documentation on this or been able to make this work?

Any insight would be greatly appreciated. I'm trying to take the user to enable in-App purchasing, and would rather not have the user manually click on Restrictions (not very obvious).

AS @Nix Wang's ANSWER THIS IS NOT WORK IN IOS 10

It's possible that the path component has a different name than the actual section, but it's also possible that you can't currently access that section straight from a URL. I found a list of possible URLs and Restrictions is not on it, maybe it's just not found out yet.

List of currently known URLs in the Settings app:

• prefs:root=General&path=About
• prefs:root=General&path=ACCESSIBILITY
• prefs:root=AIRPLANE_MODE
• prefs:root=General&path=AUTOLOCK
• prefs:root=General&path=USAGE/CELLULAR_USAGE
• prefs:root=Brightness
• prefs:root=General&path=Bluetooth
• prefs:root=General&path=DATE_AND_TIME
• prefs:root=FACETIME
• prefs:root=General
• prefs:root=General&path=Keyboard
• prefs:root=CASTLE
• prefs:root=CASTLE&path=STORAGE_AND_BACKUP
• prefs:root=General&path=INTERNATIONAL
• prefs:root=LOCATION_SERVICES
• prefs:root=ACCOUNT_SETTINGS
• prefs:root=MUSIC
• prefs:root=MUSIC&path=EQ
• prefs:root=MUSIC&path=VolumeLimit
• prefs:root=General&path=Network
• prefs:root=NIKE_PLUS_IPOD
• prefs:root=NOTES
• prefs:root=NOTIFICATIONS_ID
• prefs:root=Phone
• prefs:root=Photos
• prefs:root=General&path=ManagedConfigurationList
• prefs:root=General&path=Reset
• prefs:root=Sounds&path=Ringtone
• prefs:root=Safari
• prefs:root=General&path=Assistant
• prefs:root=Sounds
• prefs:root=General&path=SOFTWARE_UPDATE_LINK
• prefs:root=STORE
• prefs:root=TWITTER
• prefs:root=General&path=USAGE

As of iOS8 you can open the built-in Settings app with:

NSURL *url = [NSURL URLWithString:UIApplicationOpenSettingsURLString]; if ([[UIApplication sharedApplication] canOpenURL:url]) {    [[UIApplication sharedApplication] openURL:url]; } 

The actual URL string is @"app-settings:". I tried appending different sections to the string ("Bluetooth", "GENERAL", etc.) but seems only linking to the main Settings screen works. Post a reply if you find out otherwise.
