The way to jump to system setting's location service

Question

I had do a test first,then post my answer:

The document said:openURL: is deprecated in iOS10.Use openURL:options:completionHandler: instead.

Answer 1

Before iOS 10,you can use:

    [[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"App-Prefs:root=Privacy&path=LOCATION"]];

After iOS 10,you'd better use:

    [[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"App-Prefs:root=Privacy&path=LOCATION"] 
options:[NSDictionary dictionary] 
completionHandler:nil];

Answer 2

Open Location Service Setting in Swift 3:

if let url = URL(string: "App-Prefs:root=Privacy&path=LOCATION") {
    if #available(iOS 10.0, *) {
        UIApplication.shared.open(url, options: [:], completionHandler: nil)
    } else {
        UIApplication.shared.openURL(url)
    }
}

Answer 3

In Swift 3.0

let url = URL(string: "http://google.com")!
        if UIApplication.shared.canOpenURL(url) {
            UIApplication.shared.open(url, options: [:], completionHandler: nil)
        }
        else{
            NSLog("Cant open url")
        }
