ios4 - Is there a way to turn on wifi on iphone through your app's code? -

I am creating an app using the iPhone SDK 4. What programming does the WiFi on an iPhone / iPod Touch turn on Is there a way to do (especially iOS 4) if it has been locked?

Thanks,

I want to be able to turn on WiFi (if it is turned off).

No, you can not override the user's settings for the device.

You can require Wi-Fi by applying the UIRequiresPersistentWiFi key to the app Info.plist file. This will call the system dialog so that the user can ask to activate the wifi, if it is not available.
