How do I open phone settings when a button is clicked?
Using UIApplication.openSettingsURLString
Update for Swift 5.1
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 {
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)
}
⚠️ Be careful!
This answer is based on undocumented APIs and recently (since iOS12) Apple is rejecting apps with this approach.
Original answer below
Swift 5
UIApplication.shared.open(URL(string: UIApplication.openSettingsURLString)!, options: [:], completionHandler: nil)
Swift 4
UIApplication.shared.open(URL(string: UIApplicationOpenSettingsURLString)!, options: [:], completionHandler: nil)
NOTE: The following method works for all the versions below iOS 11, for higher versions the app might get rejected since it's a private API
Sometimes we want to take a user to settings other than our app settings. The following method will help you achieve that:
First, configure the URL Schemes in your project. You will find it in Target -> Info -> URL Scheme. click on + button and type prefs in URL Schemes
Swift 5
UIApplication.shared.open(URL(string: "App-prefs:Bluetooth")!)
Swift 3
UIApplication.shared.open(URL(string:"App-Prefs:root=General")!, options: [:], completionHandler: nil)
Swift
UIApplication.sharedApplication().openURL(NSURL(string:"prefs:root=General")!)
Objective-C
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"prefs:root=General"]];
and following are all the available URLs
**On IOS < 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
On IOS 13
- 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 (??)
Note: Network setting will not be opened in a simulator, but the link will work on a real device.
SWIFT 5
if let settingsUrl = URL(string: UIApplication.openSettingsURLString) {
UIApplication.shared.open(settingsUrl)
}
In iOS 8+ you can do the following:
func buttonClicked(sender:UIButton)
{
UIApplication.sharedApplication().openURL(NSURL(string: UIApplicationOpenSettingsURLString))
}
Swift 4
let settingsUrl = URL(string: UIApplicationOpenSettingsURLString)!
UIApplication.shared.open(settingsUrl)
Using @vivek's hint I develop an utils class based on Swift 3, hope you appreciate!
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)
}
}
}
This is very helpful since that API's will change for sure and you can refactor once and very fast!
