Jump to the Phone system settings page in the IOS App

In iOS development, sometimes there is a need to jump system setup interface, such as prompting the user to open the alert user to open the push or location permissions.

After IOS6, the third-party app needs to jump to the system Setup interface and need to add a prefs value to the URL type, such as:

Note: There are three ways to set up jumps, each with a different usage scenario. And when you jump to the system and apply the settings below,

Your app needs to have at least one permission in advance, such as notification, location, etc. Otherwise, it can cause a crash.

• Mode one: prefs:root= a service
• Way two: Prefs:root=bundleid
• Way three: Uiapplicationopensettingsurlstring

The following specific jump implementation:

1. Jump method:

2. 10.0*url= [nsurl urlwithstring:@ "prefs:root=location_services"]; if  10.0   if([[uiapplication Sharedapplication]canopenurl:url]) {[[ UIApplication sharedapplication]openurl:url options:@{}completionhandler:^(BOOL  success) {}];}

2. Jump to the specific location: (different ways to specify)

• Way One:

When iOS system version <= iOS7, you can only jump to the system settings page:

Example: Jump to: Privacy-location services. Nsurl *url= [Nsurl urlwithstring:@] Prefs:root=location_services

prefs:root= a service

System settings: prefs:root=internet_tethering WIFI settings: Prefs:root=wifi Bluetooth settings: Prefs:root=bluetooth system notification: prefs:root=notifications _ID Universal Settings: prefs:root=general display settings: prefs:root=display&brightness wallpaper settings: prefs:root=wallpaper Sound settings: prefs:root= Sounds privacy settings: prefs:root=privacy cellular: prefs:root=mobile_data_settings_id Music: Prefs:root=music

Album ":p Refs:root=photos

　　
   This way of jumping, is to jump to the system settings interface.

• Way two:

　　　　When iOS system version >= iOS8, support jump to third party app's settings interface

With Prefs:root=bundleid, Bundleid is the unique ID of your third-party app project

　　　　Limitations: Only support the IOS8,IOS9 system, on the IOS10 system, will not jump.

On the iOS7 system, just jump to the settings app, not recommended.

　　　　If you need to continue to jump to the inner layer of the project, you can add the path path by adding the following:

About this machine: prefs:root=general&path=about

Software Upgrade: Prefs:root=general&path=software_update_link

Date Time: Prefs:root=general&path=date_and_time

Accessibility:prefs:root=general&path=accessibility

Keyboard settings: Prefs:root=general&path=keyboard

Sound settings: prefs:root=sounds

Privacy settings: prefs:root=privacy

APP Store:prefs:root=store

Restore settings: Prefs:root=general&path=reset

App notifications: Boundleid for prefs:root=notifications_id&path= applications

Location: prefs:root=location_services

Cellular network: prefs:root=mobile_data_settings_id

Vpn-prefs:root=general&path=network/vpn

Wi-fi:prefs:root=wifi

Location Services: prefs:root=location_services

Personal hotspot: prefs:root=internet_tethering

Auxiliary function: prefs:root=general&path=accessibility

Flight mode: Prefs:root=airplane_mode

Bluetooth: Prefs:root=general&path=bluetooth

Settings: prefs:root=general

Network-prefs:root=general&path=network

Notes-prefs:root=notes

Photos-prefs:root=photos

Sounds-prefs:root=sounds

Software Update-prefs:root=general&path=software_update_link

Store-prefs:root=store

• Mode three

jump to System settings is not supported when iOS system version >= iOS8 support jump to your app settings.

Nsurl *url = [Nsurl urlwithstring:uiapplicationopensettingsurlstring];

　　　　uiapplicationopensettingsurlstring is provided on the IOS8, support IOS8,IOS9,IOS10 system, recommended use.

the Prefs:root=bundleid and prefs:root= services will not work.
