如果这是你想要的，这可能会占用你应用程序的特定设置。

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

UIApplication.open(_:options:completionHandler:)只能在主线程中使用

解决方案:

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

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

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"

}

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)
        }
    }

}

这是非常有用的，因为API肯定会改变，你可以快速重构一次!

在ios10/ Xcode 8模拟器:

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

作品

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

没有。

如果这是你想要的，这可能会占用你应用程序的特定设置。

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

⚠️小心! 这个答案是基于未记录的api，最近(从iOS12开始)苹果拒绝使用这种方法的应用程序。

以下是原始答案

斯威夫特5

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，因为它是一个私有API

有时我们想让用户进入应用程序设置以外的设置。 下面的方法将帮助你实现这个目标:

首先，在项目中配置URL方案。你会发现它在目标->信息-> URL方案。点击+按钮，在URL方案中输入prefs

斯威夫特5

UIApplication.shared.open(URL(string: "App-prefs:Bluetooth")!)

斯威夫特3

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

斯威夫特

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

objective - c

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

和下面是所有可用的url

**在IOS上< 12 **

prefs:root=General&path=About prefs:root=General&path=ACCESSIBILITY prefs:root=AIRPLANE_MODE prefs:root=General&path=AUTOLOCK prefs:root=General&path=USAGE/CELLULAR_USAGE prefs:root=Brightness prefs:root=Bluetooth prefs:root=General&path=DATE_AND_TIME prefs:root=FACETIME prefs:root=General prefs:root=General&path=Keyboard prefs:root=CASTLE prefs:root=CASTLE&path=STORAGE_AND_BACKUP prefs:root=General&path=INTERNATIONAL prefs:root=LOCATION_SERVICES prefs:root=ACCOUNT_SETTINGS prefs:root=MUSIC prefs:root=MUSIC&path=EQ prefs:root=MUSIC&path=VolumeLimit prefs:root=General&path=Network prefs:root=NIKE_PLUS_IPOD prefs:root=NOTES prefs:root=NOTIFICATIONS_ID prefs:root=Phone prefs:root=Photos prefs:root=General&path=ManagedConfigurationList prefs:root=General&path=Reset prefs:root=Sounds&path=Ringtone prefs:root=Safari prefs:root=General&path=Assistant prefs:root=Sounds prefs:root=General&path=SOFTWARE_UPDATE_LINK prefs:root=STORE prefs:root=TWITTER prefs:root=FACEBOOK prefs:root=General&path=USAGE prefs:root=VIDEO prefs:root=General&path=Network/VPN prefs:root=Wallpaper prefs:root=WIFI prefs:root=INTERNET_TETHERING prefs:root=Phone&path=Blocked prefs:root=DO_NOT_DISTURB

在IOS 13上

App-prefs:General&path=About App-prefs:AIRPLANE_MODE App-prefs:General&path=AUTOLOCK App-prefs:Bluetooth App-prefs:General&path=DATE_AND_TIME App-prefs:FACETIME App-prefs:General App-prefs:General&path=Keyboard App-prefs:CASTLE App-prefs:CASTLE&path=STORAGE_AND_BACKUP App-prefs:General&path=INTERNATIONAL App-prefs:MUSIC App-prefs:NOTES App-prefs:NOTIFICATIONS_ID App-prefs:Phone App-prefs:Photos App-prefs:General&path=ManagedConfigurationList App-prefs:General&path=Reset App-prefs:Sounds&path=Ringtone App-prefs:Sounds App-prefs:General&path=SOFTWARE_UPDATE_LINK App-prefs:STORE App-prefs:Wallpaper App-prefs:WIFI App-prefs:INTERNET_TETHERING App-prefs:DO_NOT_DISTURB Not tested App-prefs:TWITTER (??) App-prefs:FACEBOOK (??) App-prefs:NIKE_PLUS_IPOD (??)
