我正在使用Swift和Xcode。使用
UIApplication.opensetingsurlstring
Swift 5.1的更新
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: UIApplication.openSettingsURLString) 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 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 {

SWIFT 5
if let settingsUrl = URL(string: UIApplication.openSettingsURLString) {
UIApplication.shared.open(settingsUrl)
}
UIApplication.shared.open(URL(string: UIApplication.openSettingsURLString)!, options: [:], completionHandler: nil)
UIApplication.shared.open(URL(string: "App-prefs:Bluetooth")!)
在iOS 8+中,您可以执行以下操作:
func buttonClicked(sender:UIButton)
{
UIApplication.sharedApplication().openURL(NSURL(string: UIApplicationOpenSettingsURLString))
}
Swift 4
let settingsUrl = URL(string: UIApplicationOpenSettingsURLString)!
UIApplication.shared.open(settingsUrl)
UIApplication.shared.open(URL(string: UIApplicationOpenSettingsURLString)!, options: [:], completionHandler: nil)
⚠️ 小心
这个答案基于未记录的API,最近(自iOS12以来),苹果拒绝使用这种方法的应用程序
原始答案如下
Swift 5
if let settingsUrl = URL(string: UIApplication.openSettingsURLString) {
UIApplication.shared.open(settingsUrl)
}
UIApplication.shared.open(URL(string: UIApplication.openSettingsURLString)!, options: [:], completionHandler: nil)
UIApplication.shared.open(URL(string: "App-prefs:Bluetooth")!)
Swift 4
let settingsUrl = URL(string: UIApplicationOpenSettingsURLString)!
UIApplication.shared.open(settingsUrl)
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,应用程序可能会被拒绝,因为它是一个私有API
有时,我们希望将用户带到应用程序设置以外的其他设置。
以下方法将帮助您实现这一目标:
首先,在项目中配置URL方案。您将在目标->信息->URL方案中找到它。单击+按钮并在URL方案中键入prefs
Swift 5
if let settingsUrl = URL(string: UIApplication.openSettingsURLString) {
UIApplication.shared.open(settingsUrl)
}
UIApplication.shared.open(URL(string: UIApplication.openSettingsURLString)!, options: [:], completionHandler: nil)
UIApplication.shared.open(URL(string: "App-prefs:Bluetooth")!)
Swift 3
UIApplication.shared.open(URL(string:"App-Prefs:root=General")!, options: [:], completionHandler: nil)
UIApplication.shared.openURL(URL(string:"prefs:root=General")!)
Swift
UIApplication.sharedApplication().openURL(NSURL(string:"prefs:root=General")!)
目标-C
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"prefs:root=General"]];
下面是所有可用的URL
**关于IOS<12**

注意:网络设置不会在模拟器中打开,但链接将在真实设备上工作。在模拟器的ios10/Xcode 8中:
UIApplication.shared.openURL(URL(string:UIApplicationOpenSettingsURLString)!)
工作
没有。我看到了这行代码
UIApplication.sharedApplication() .openURL(NSURL(string:"prefs:root=General")!)
不起作用,它在ios10/Xcode 8中对我不起作用,只是一个小的代码差异,请用
UIApplication.sharedApplication().openURL(NSURL(string:"App-Prefs:root=General")!)
Swift3
UIApplication.shared.open(URL(string:"App-Prefs:root=General")!, options: [:], completionHandler: nil)
UIApplication.shared.openURL(URL(string:"prefs:root=General")!)
取代
UIApplication.shared.openURL(URL(string:"App-Prefs:root=General")!)
希望能有帮助。
干杯。如上@niravdesai所说的应用程序优先。 我发现
App Prefs:
适用于iOS 9、10和11。测试过的设备。
其中asprefs:
仅适用于iOS 9。来自的第一个响应适用于iOS 10.3
if let appSettings = URL(string: UIApplicationOpenSettingsURLString + Bundle.main.bundleIdentifier!) {
if UIApplication.shared.canOpenURL(appSettings) {
UIApplication.shared.open(appSettings)
}
}
SWIFT 4
let settingsUrl = URL(string: UIApplicationOpenSettingsURLString)!
UIApplication.shared.open(settingsUrl)
UIApplication.shared.open(URL(string: UIApplicationOpenSettingsURLString)!, options: [:], completionHandler: nil)
这可能需要你的应用程序的特定设置,如果这是你想要的
UIApplication.shared.openURL(URL(string: UIApplicationOpenSettingsURLString)!)
使用@vivek的提示,我开发了一个基于swift3的utils类,希望您能欣赏
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"
}
这是非常有帮助的,因为API肯定会改变,您可以重构一次并且非常快
App-Prefs:root=Privacy&path=LOCATION
为我提供了常规位置设置。注:仅适用于设备。添加到@Luca Davanzo
iOS 11,某些权限设置已移动到应用程序路径:
iOS 11支持
警告:
prefs:root
或App-prefs:root
URL方案被视为私有API。如果您使用这些应用程序,苹果可能会拒绝您的应用程序,以下是您在提交应用程序时可能得到的信息:
您的应用程序使用“prefs:root=”非公共URL方案,这是一个私有实体。不允许在App Store上使用非公共API,因为如果这些API发生变化,可能会导致糟糕的用户体验。在本应用程序的未来提交中继续使用或隐藏非公共API可能会导致y的终止
