Notification — prefs:root=NOTIFICATI_IDPhone — prefs:root=PhonePhotos — prefs:root=PhotosProfile — prefs:root=General&path=ManagedConfigurationListReset — prefs:root=General&path=ResetSafari — prefs:root=SafariSiri — prefs:root=General&path=AssistantSounds — prefs:root=SoundsSoftware Update — prefs:root=General&path=SOFTWARE_UPDATE_LINKStore — prefs:root=STORETwitter — prefs:root=TWITTERUsage — prefs:root=General&path=USAGEVPN — prefs:root=General&path=Network/VPNWallpaper — prefs:root=WallpaperWi-Fi — prefs:root=WIFI

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

This can be redirected in iOS6, 7, and 8, but there is still one step missing.

Method 2:

[[UIApplication sharedApplication] openURL: [NSURL URLWithString: @ "prefs: root = WIFI"];
But it can only be available in alertview.
