由于openURL(_::)在iOS 10.0之后已被弃用，请使用open(_:options:completionHandler:)代替。

if let settingsUrl = URL(string: UIApplication.openSettingsURLString)  {
        UIApplication.shared.open(settingsUrl, options: [:]) { completed in
             if !completed {
                 print("Failed opening")
             }
        }
}

我更喜欢以更安全的方式打开设置，

if let settingUrl = URL(string:UIApplicationOpenSettingsURLString) {

    UIApplication.shared.open(settingUrl)
}
else {
    print("Setting URL invalid")
}

iOS 10更新

苹果将该方法更改为在主线程上打开async。但是，从现在开始，只能在本机设置中打开应用程序设置。

[[UIApplication sharedApplication] openURL:url options:@{} completionHandler:nil];

iOS 9更新

现在可以直接进入子设置菜单。但是，需要创建URL方案。有两种方法:

XCode -你会在目标，信息，URL方案中找到它。然后，输入prefs。 直接添加到*-Info.plist。增加如下内容: <键> CFBundleURLTypes关键> < / < >数组 < dict > <键> CFBundleTypeRole关键> < / <字符串>编辑字符串> < / <键> CFBundleURLSchemes关键> < / < >数组 <字符串>首选项> < /字符串 > < /数组 < / dict > > < /数组

然后代码:

斯威夫特

UIApplication.sharedApplication () .openURL (NSURL(弦:“首选项:根=一般路径=键盘”)!)

objective - c

[eapplication sharedApplication] openURL:[NSURL优先字符串:

在Swift 3 / iOS 10+中看起来是这样的

if let url = URL(string: "App-Prefs:root=LOCATION_SERVICES") {
    UIApplication.shared.open(url, completionHandler: .none)
}

似乎你可以使用prefs:<area> URL来打开设置并进入特定的区域。苹果可能会改变这些，破坏你的应用程序，所以一定要先检查你是否能打开它们。
