打开位置设置在iOS 11中不起作用

Question

I'm using this code to redirect to iOS settings for the location:

NSURL *url = [NSURL URLWithString:@"App-Prefs:root=LOCATION_SERVICES"];

if ([[UIApplication sharedApplication] canOpenURL:url]) {
    [[UIApplication sharedApplication] openURL:url options:@{} completionHandler:nil];
}

But it is just redirecting to settings and not in location or bluetooth settings. Does anybody know if is any way to redirect to iOS location settings?

Thank you

Answer 1

Declare url as:

NSURL *url = [NSURL URLWithString:@"App-Prefs:root=LOCATION_SERVICES"];

thus:

if ([[UIApplication sharedApplication] canOpenURL:url]) {
    [[UIApplication sharedApplication] openURL: url];
}

NOTE:

The above approach should work for iOS 10.x and below (you could check: How to programmatically open the WIFI settings in Objective-C on iOS 10 ). However, the "app-prefs" URL scheme is not supported by Apple! prefs URLs are considered as private APIs, the only documented preference URL is the UIApplicationOpenSettingsURLString . Obviously, is has nothing to do with the used programming language; Related:

• Swift 4 - IOS 11 / “Apps-prefs=root” function not working
• IOS 11 / "Apps-prefs=root" function not working after update to Swift 3

Roughly speaking, you are not able to do such a navigation anymore on iOS 11.

Answer 2

You can use UIApplicationOpenSettingsURLString . If your application uses location data or bluetooth you will see location and bluetooth settings there.

[[UIApplication sharedApplication] openURL:[NSURL URLWithString:UIApplicationOpenSettingsURLString]];

First: Click on project name >> target>> Info >> url Types >> URL Schemes. For example you can see the screenshot.

Then use the code:

-(IBAction)openSettingViewToEnableLocationService:(id)sender
{
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"prefs:root=LOCATION_SERVICES"]];
}
