Call the official Settings app from my app on iPhone

Question

I want to send the user to the official Settings app at some point in my app. I would also prefer to open the Settings app's Network section immediately.

I believe I require the format and URL scheme for the Settings app to construct my request. But I don't think it's against the law to name such an official app.

Can somebody assist me?

Answer 1

It also functions in iOS versions greater than 5.1, however you must include URL schemes in the URL types in Xcode:

Then you can use

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

It's an open system WiFi setting now.
