how to programmatically open the WIFI settings in objective c in iOS9

问题

I'm trying to access the WIFI settings through my application using Objective-C. But can not find any way. Could someone help me?

Already tested with:

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

Does not work on iOS 9.

回答1:

This is my code

if (&UIApplicationOpenSettingsURLString != NULL) { 
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"prefs:root=WIFI"]]; 
}

Try to add prefs to URL schemes like https://stackoverflow.com/a/31253743/3668465 did

This works fine on iOS 10,

Go to Targets --> (Application) --> Info --> URL Types --> +

In the URL Schemes write

prefs

Then Call,

- (void)openWifiSettings
{
    if ([[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:@"prefs:root=WIFI"]]) {
        [[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"prefs:root=WIFI"]];
    } else {
        [[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"App-Prefs:root=WIFI"]];
    }
}

As per Apple's New Review standards, we are not supposed to use this way to open Wi-Fi Settings. I have been using this for long time in my app and recently Apple rejected with the below comment.

Your app uses the "prefs:root=" non-public URL scheme, which is a private entity. The use of non-public APIs is not permitted on the App Store because it can lead to a poor user experience should these APIs change.

So you can just navigate to settings of the app by using UIApplicationOpenSettingsURLString.

Swift Code:

if let settingsUrl = URL.init(string: UIApplicationOpenSettingsURLString), UIApplication.shared.canOpenURL(settingsUrl) {
                    UIApplication.shared.openURL(settingsUrl)
                }

All conditions:

    NSURL * urlCheck1 = [NSURL URLWithString:@"App-Prefs:root=WIFI"];
    NSURL * urlCheck2 = [NSURL URLWithString:@"prefs:root=WIFI"];
    NSURL * urlCheck3 = [NSURL URLWithString:UIApplicationOpenSettingsURLString];

    if ([[UIApplication sharedApplication] canOpenURL:urlCheck1])
    {
        [[UIApplication sharedApplication] openURL:urlCheck1];
    }
    else if ([[UIApplication sharedApplication] canOpenURL:urlCheck2])
    {
        [[UIApplication sharedApplication] openURL:urlCheck2];
    }
    else if ([[UIApplication sharedApplication] canOpenURL:urlCheck3])
    {
        [[UIApplication sharedApplication] openURL:urlCheck3];
    }
    else
    {
        //Unable to open settings app.
    }

You can't get straight to wifi setting with openURL. All you can do is to open settings for your own app.

if (&UIApplicationOpenSettingsURLString != nil) {
   NSURL *URL = [NSURL URLWithString:UIApplicationOpenSettingsURLString];
   [[UIApplication sharedApplication] openURL:URL];
} else {
  ...
}

回答6:

//Pre iOS 10
NSURL *url = [NSURL URLWithString:@"prefs:root=WIFI"];
if (![[UIApplication sharedApplication] canOpenURL:url])
{   //iOS 10+
    url = [NSURL URLWithString:@"App-Prefs:root=WIFI"];
}
[[UIApplication sharedApplication] openURL:url];

Swift 4.2, iOS 12

This is the function that I'm currently using in my app for it:

extension UIApplication {

    ...

    @discardableResult
    static func openAppSetting() -> Bool {
        guard
            let settingsURL = URL(string: UIApplication.openSettingsURLString),
            UIApplication.shared.canOpenURL(settingsURL)
            else {
                return false
        }

        UIApplication.shared.open(settingsURL)
        return true
    }
}

Usage: UIApplication.openAppSetting()

I also used non-public URL scheme, such as: prefs:root=, but my app was rejected. So if you're trying to do more specific stuff with deeplinking, don't waste your time because at the moment you can't!

You can use this option:

iOS >= 4.1 it's possible to obtain SSID of wireless network that device is currenctly connected to.

For this you'd use function CNCopyCurrentNetworkInfo

Details on implemenation: iPhone get SSID without private library
