单击按钮时如何打开手机设置?

问题描述 投票:131回答:13

我正在尝试在应用程序中实现一项功能,该功能在互联网连接不可用时显示警报。警报有两个操作(确定和设置),每当用户点击设置时,我想以编程方式将它们带到手机设置。

我正在使用Swift和Xcode。

使用UIApplicationOpenSettingsURLString

更新Swift 4.2

override func viewDidAppear(_ animated: Bool) {
    let alertController = UIAlertController (title: "Title", message: "Go to Settings?", preferredStyle: .alert)

    let settingsAction = UIAlertAction(title: "Settings", style: .default) { (_) -> Void in

        guard let settingsUrl = URL(string: UIApplicationOpenSettingsURLString) else {
            return
        }

        if UIApplication.shared.canOpenURL(settingsUrl) {
            UIApplication.shared.open(settingsUrl, completionHandler: { (success) in
                print("Settings opened: \(success)") // Prints true
            })
        }
    }
    alertController.addAction(settingsAction)
    let cancelAction = UIAlertAction(title: "Cancel", style: .default, handler: nil)
    alertController.addAction(cancelAction)

    present(alertController, animated: true, completion: nil)
}

Swift 2.x

使用UIApplicationOpenSettingsURLString

override func viewDidAppear(animated: Bool) {
    var alertController = UIAlertController (title: "Title", message: "Go to Settings?", preferredStyle: .Alert)

    var settingsAction = UIAlertAction(title: "Settings", style: .Default) { (_) -> Void in
        let settingsUrl = NSURL(string: UIApplicationOpenSettingsURLString)
        if let url = settingsUrl {
            UIApplication.sharedApplication().openURL(url)
        }
    }

    var cancelAction = UIAlertAction(title: "Cancel", style: .Default, handler: nil)
    alertController.addAction(settingsAction)
    alertController.addAction(cancelAction)

    presentViewController(alertController, animated: true, completion: nil)
}

添加到@Luca Davanzo

iOS 11,一些权限设置已移至应用程序路径:

iOS 11支持

 static func open(_ preferenceType: PreferenceType) throws {
    var preferencePath: String
    if #available(iOS 11.0, *), preferenceType == .video || preferenceType == .locationServices || preferenceType == .photos {
        preferencePath = UIApplicationOpenSettingsURLString
    } else {
        preferencePath = "\(PreferencesExplorer.preferencePath)=\(preferenceType.rawValue)"
    }

    if let url = URL(string: preferencePath) {
        if #available(iOS 10.0, *) {
            UIApplication.shared.open(url, options: [:], completionHandler: nil)
        } else {
            UIApplication.shared.openURL(url)
        }
    } else {
        throw PreferenceExplorerError.notFound(preferencePath)
    }
}

警告:prefs:rootApp-Prefs:root URL方案被视为私有API。如果您使用Apple,Apple可能拒绝您的应用程序,这是您在提交应用程序时可能会得到的内容:

您的应用使用“prefs:root =”非公共URL方案,这是一个私有实体。 App Store上不允许使用非公共API,因为如果这些API发生变化,可能会导致糟糕的用户体验。在将来提交此应用程序时继续使用或隐藏非公共API可能会导致Apple Developer帐户被终止,以及从App Store中删除所有相关应用程序。

下一步

要解决此问题,请修改您的应用以使用公共API提供相关功能,或使用“prefs:root”或“App-Prefs:root”URL方案删除功能。

如果没有其他方法可以提供您的应用所需的功能,则可以提交增强请求。

这可以采取您的应用程序的具体设置,如果这是您正在寻找的。

UIApplication.shared.openURL(URL(string: UIApplicationOpenSettingsURLString)!)

如上所述@niravdesai说App-prefs。我发现App-Prefs:适用于iOS 9,10和11设备测试。 prefs:仅适用于iOS 9。

UIApplication.shared.open(URL(string: UIApplication.openSettingsURLString)!, options: [:], completionHandler: nil)

斯威夫特4

UIApplication.shared.open(URL(string: UIApplicationOpenSettingsURLString)!, options: [:], completionHandler: nil)

注意:以下方法适用于iOS 11以下的所有版本,对于更高版本的应用程序可能会被拒绝,因为它是私有API

有时我们希望将用户带到我们的应用设置以外的设置。以下方法将帮助您实现:

首先,在项目中配置URL Schemes。您可以在Target - > Info - > URL Scheme中找到它。单击+按钮并在URL Schemes中键入prefs

斯威夫特3

UIApplication.shared.open(URL(string:"App-Prefs:root=General")!, options: [:], completionHandler: nil)

迅速

UIApplication.sharedApplication().openURL(NSURL(string:"prefs:root=General")!)

Objective-C的

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

以下是所有可用的URL

  • 首选项:根=通用及路径=关于
  • 首选项:根=通用及路径= ACCESSIBILITY
  • 首选项:根= AIRPLANE_MODE

在iOS 8+中,您可以执行以下操作:

 func buttonClicked(sender:UIButton)
    {
        UIApplication.sharedApplication().openURL(NSURL(string: UIApplicationOpenSettingsURLString))
    }

    let settingsUrl = URL(string: UIApplicationOpenSettingsURLString)!
    UIApplication.shared.open(settingsUrl)

使用@vivek的提示我开发了一个基于Swift 3的utils类,希望你欣赏!

import Foundation
import UIKit

public enum PreferenceType: String {

    case about = "General&path=About"
    case accessibility = "General&path=ACCESSIBILITY"
    case airplaneMode = "AIRPLANE_MODE"
    case autolock = "General&path=AUTOLOCK"
    case cellularUsage = "General&path=USAGE/CELLULAR_USAGE"
    case brightness = "Brightness"
    case bluetooth = "Bluetooth"
    case dateAndTime = "General&path=DATE_AND_TIME"
    case facetime = "FACETIME"
    case general = "General"
    case keyboard = "General&path=Keyboard"
    case castle = "CASTLE"
    case storageAndBackup = "CASTLE&path=STORAGE_AND_BACKUP"
    case international = "General&path=INTERNATIONAL"
    case locationServices = "LOCATION_SERVICES"
    case accountSettings = "ACCOUNT_SETTINGS"
    case music = "MUSIC"
    case equalizer = "MUSIC&path=EQ"
    case volumeLimit = "MUSIC&path=VolumeLimit"
    case network = "General&path=Network"
    case nikePlusIPod = "NIKE_PLUS_IPOD"
    case notes = "NOTES"
    case notificationsId = "NOTIFICATIONS_ID"
    case phone = "Phone"
    case photos = "Photos"
    case managedConfigurationList = "General&path=ManagedConfigurationList"
    case reset = "General&path=Reset"
    case ringtone = "Sounds&path=Ringtone"
    case safari = "Safari"
    case assistant = "General&path=Assistant"
    case sounds = "Sounds"
    case softwareUpdateLink = "General&path=SOFTWARE_UPDATE_LINK"
    case store = "STORE"
    case twitter = "TWITTER"
    case facebook = "FACEBOOK"
    case usage = "General&path=USAGE"
    case video = "VIDEO"
    case vpn = "General&path=Network/VPN"
    case wallpaper = "Wallpaper"
    case wifi = "WIFI"
    case tethering = "INTERNET_TETHERING"
    case blocked = "Phone&path=Blocked"
    case doNotDisturb = "DO_NOT_DISTURB"

}

enum PreferenceExplorerError: Error {
    case notFound(String)
}

open class PreferencesExplorer {

    // MARK: - Class properties -

    static private let preferencePath = "App-Prefs:root"

    // MARK: - Class methods -

    static func open(_ preferenceType: PreferenceType) throws {
        let appPath = "\(PreferencesExplorer.preferencePath)=\(preferenceType.rawValue)"
        if let url = URL(string: appPath) {
            if #available(iOS 10.0, *) {
                UIApplication.shared.open(url, options: [:], completionHandler: nil)
            } else {
               UIApplication.shared.openURL(url)
            }
        } else {
            throw PreferenceExplorerError.notFound(appPath)
        }
    }

}

这非常有用,因为API肯定会发生变化,你可以快速重构一次!

App-Specific URL Schemes的第一个回复在iOS 10.3上为我工作。

if let appSettings = URL(string: UIApplicationOpenSettingsURLString + Bundle.main.bundleIdentifier!) {
    if UIApplication.shared.canOpenURL(appSettings) {
      UIApplication.shared.open(appSettings)
    }

在模拟器中的ios10 / Xcode 8中:

UIApplication.shared.openURL(URL(string:UIApplicationOpenSettingsURLString)!)

作品

UIApplication.shared.openURL(URL(string:"prefs:root=General")!)

才不是。

我见过这行代码

UIApplication.sharedApplication() .openURL(NSURL(string:"prefs:root=General")!)

不工作,它在ios10 / Xcode 8中对我不起作用,只是一个小的代码差异,请替换它

UIApplication.sharedApplication().openURL(NSURL(string:"App-Prefs:root=General")!)

Swift3

UIApplication.shared.openURL(URL(string:"prefs:root=General")!)

用。。。来代替

UIApplication.shared.openURL(URL(string:"App-Prefs:root=General")!)

希望能帮助到你。干杯。

Swift 4.2,iOS 12

open(url:options:completionHandler:)方法已更新为包含非零选项字典,该帖子仅包含一个类型为UIApplication.OpenExternalURLOptionsKey的可能选项(在示例中)。

@objc func openAppSpecificSettings() {

    guard let url = URL(string: UIApplication.openSettingsURLString),
        UIApplication.shared.canOpenURL(url) else {
            return
    }

    let optionsKeyDictionary = [UIApplication.OpenExternalURLOptionsKey(rawValue: "universalLinksOnly"): NSNumber(value: true)]

    UIApplication.shared.open(url, options: optionsKeyDictionary, completionHandler: nil)

}

明确构建一个URL,例如“App-Prefs”,AFAIK已经从商店中删除了一些应用程序。
