In the Facebook app of iOS when the user open the app without turning on Wi-Fi, there is a UIAlertView pops up,
Location Accuracy
Turning on Wi-Fi will improve location accuracy.
Settings Ok
How can I detect this Wi-Fi on/off in iOS & also I want to redirect to the settings page of Wi-Fi settings to user to turn on Wi-Fi. I have seen lot of people told that it's not possible to do redirecting to settings page. But in this Facebook app it is possible. How can I do it in my app??
