IOS 启动设置-> 限制网址方案

我最近发现了令人敬畏的 IOS5自定义设置 URL 方案，这可以在这个伟大的 网站详细解释。

我发现这个方法很有效，可以将用户从我的应用程序中引导到设置应用程序:

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

但似乎不能通过 path参数直接路由到 限制路径:

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

有没有人找到相关文件，或者有办法解决这个问题？

如果你能提供点线索，我将不胜感激。我试图让用户启用应用程序内购买，而不是让用户手动点击限制(不是很明显)。

AS @Nix Wang's ANSWER THIS IS NOT WORK IN IOS 10

WARNING: This method will not work for devices running iOS 5.1 and greater - See Hlung's comment below.

It's possible that the path component has a different name than the actual section, but it's also possible that you can't currently access that section straight from a URL. I found a list of possible URLs and Restrictions is not on it, maybe it's just not found out yet.

List of currently known URLs in the Settings app:

  • 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=General&path=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=General&path=USAGE
  • prefs:root=VIDEO
  • prefs:root=General&path=Network/VPN
  • prefs:root=Wallpaper
  • prefs:root=WIFI
  • prefs:root=INTERNET_TETHERING

Yep, saw this (and many more), even implemented it in a test application. Really need to get the definitive word from Apple, but the community consensus opinion is Apple disallowed it in 5.1 after it was publicly "discovered/published", so applications containing it won't be accepted.

08/01/12 Update: Asked Apple through my developer account if there is a way to programmatically launch the WiFi Settings dialog. Here is the response:

"Our engineers have reviewed your request and have concluded that there is no supported way to achieve the desired functionality given the currently shipping system configurations."

As of iOS8 you can open the built-in Settings app with:

NSURL *url = [NSURL URLWithString:UIApplicationOpenSettingsURLString];
if ([[UIApplication sharedApplication] canOpenURL:url]) {
[[UIApplication sharedApplication] openURL:url];
}

The actual URL string is @"app-settings:". I tried appending different sections to the string ("Bluetooth", "GENERAL", etc.) but seems only linking to the main Settings screen works. Post a reply if you find out otherwise.

If you add the prefs URL scheme to your iOS app, it will allow you to use all those schemes that we could in iOS 5. I've tested it on iOS 9, but I think it will work on older versions too.

I wanted to open the Bluetooth Menu in the Settings Application and the above path (prefs:root=General&path=Bluetooth) didn't work for me. What ended up working for me was 

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

Make sure you have the prefs URL Scheme defined first.

In iOS 9 it works again!

To open Settings > General > Keyboard, I use:

prefs:root=General&path=Keyboard

Moreover, it is possible to go farther to Keyboards:

prefs:root=General&path=Keyboard/KEYBOARDS

Here is something else I found:

  1. After I have the "prefs" URL Scheme defined, "prefs:root=Safari&path=ContentBlockers" is working on Simulator (iOS 9.1 English), but not working on Simulator (Simplified Chinese). It just jump to Safari, but not Content Blockers. If your app is international, be careful.
    Update: Don't know why, now I can't jump into ContentBlockers anymore, the same code, the same version, doesn't work now. :(

  2. On real devcies (mine is iPhone 6S & iPad mini 2), "Safari" should be "SAFARI", "Safari" not working on real device, "SAFARI" now working on simulator:

    #if arch(i386) || arch(x86_64)
// Simulator
let url = NSURL(string: "prefs:root=Safari")!
#else
// Device
let url = NSURL(string: "prefs:root=SAFARI")!
#endif


if UIApplication.sharedApplication().canOpenURL(url) {
UIApplication.sharedApplication().openURL(url)
}

  3. So far, did not find any differences between iPhone and iPad.

I am updating one news here. Using 'prefs:' only is NOT rejected by Apple, I tested it and checked approved to the app store(in Aug, 2016). thx.

小开

Update:

prefs: will NOT work since iOS 10.

Works Fine for App Notification settings on IOS 10 (tested)

if(&UIApplicationOpenSettingsURLString != nil){
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:UIApplicationOpenSettingsURLString]];
}

As of iOS10 you can use 

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

to open general settings.

also you can add known urls(you can see them in the most upvoted answer) to it to open specific settings. For example the below one opens touchID and passcode.

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

Solution for iOS10. Works fine.

NSURL *URL = [NSURL URLWithString:@"App-prefs:root=TWITTER"];
[[UIApplication sharedApplication] openURL:URL options:@{} completionHandler:nil];
小开

iOS 10

Use app-prefs:

App-prefs:root=MOBILE_DATA_SETTINGS_ID

See gist
