iOS应用内跳转系统设置相关界面的方法

iOS应用内跳转系统设置相关界面的方法

        在iOS开发中，有时会有跳转系统设置界面的需求，例如提示用户打开蓝牙或者WIFI，提醒用户打开推送或者位置权限等。在iOS6之后，第三方应用需要跳转系统设置界面，需要在URL type中添加一个prefs值，如下图：

        跳转系统设置根目录中的项目使用如下的方法：

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18

_array = @[                 @{@ "系统设置" :@ "prefs:root=INTERNET_TETHERING" },                 @{@ "WIFI设置" :@ "prefs:root=WIFI" },                 @{@ "蓝牙设置" :@ "prefs:root=Bluetooth" },                 @{@ "系统通知" :@ "prefs:root=NOTIFICATIONS_ID" },                 @{@ "通用设置" :@ "prefs:root=General" },                 @{@ "显示设置" :@ "prefs:root=DISPLAY&BRIGHTNESS" },                 @{@ "壁纸设置" :@ "prefs:root=Wallpaper" },                 @{@ "声音设置" :@ "prefs:root=Sounds" },                 @{@ "隐私设置" :@ "prefs:root=privacy" },                 @{@ "APP Store" :@ "prefs:root=STORE" },                 @{@ "Notes" :@ "prefs:root=NOTES" },                 @{@ "Safari" :@ "prefs:root=Safari" },                 @{@ "Music" :@ "prefs:root=MUSIC" },                 @{@ "photo" :@ "prefs:root=Photos" }                 ];          NSURL * url = [NSURL URLWithString:[_array[index] allValues].firstObject];          [[UIApplication sharedApplication]openURL:url];

如果要跳转第三方应用的设置界面中，使用prefs:root=boundleId的方式，boundleId是第三方应用的boundleId。

        如果需要继续向项目内层进行跳转，可以通过添加path路径的方式，如下：

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14

_array = @[                 @{@ "关于本机" :@ "prefs:root=General&path=About" },                 @{@ "软件升级" :@ "prefs:root=General&path=SOFTWARE_UPDATE_LINK" },                 @{@ "日期时间" :@ "prefs:root=General&path=DATE_AND_TIME" },                 @{@ "Accessibility" :@ "prefs:root=General&path=ACCESSIBILITY" },                 @{@ "键盘设置" :@ "prefs:root=General&path=Keyboard" },                 @{@ "VPN" :@ "prefs:root=General&path=VPN" },                 @{@ "壁纸设置" :@ "prefs:root=Wallpaper" },                 @{@ "声音设置" :@ "prefs:root=Sounds" },                 @{@ "隐私设置" :@ "prefs:root=privacy" },                 @{@ "APP Store" :@ "prefs:root=STORE" },                 @{@ "还原设置" :@ "prefs:root=General&path=Reset" },                 @{@ "应用通知" :@ "prefs:root=NOTIFICATIONS_ID&path=应用的boundleId" }                 ];

----------------------------------------------------------------------------------------------------------------------

如下是跳转到系统设置诸多界面的url 

1. prefs:root=General&path=About
   
2. prefs:root=General&path=ACCESSIBILITY
   
3. prefs:root=AIRPLANE_MODE
   
4. prefs:root=General&path=AUTOLOCK
   
5. prefs:root=General&path=USAGE/CELLULAR_USAGE
   
6. prefs:root=Brightness
   
7. prefs:root=General&path=Bluetooth
   
8. prefs:root=General&path=DATE_AND_TIME
   
9. prefs:root=FACETIME
   
10. prefs:root=General
    
11. prefs:root=General&path=Keyboard
    
12. prefs:root=CASTLE
    
13. prefs:root=CASTLE&path=STORAGE_AND_BACKUP
    
14. prefs:root=General&path=INTERNATIONAL
    
15. prefs:root=LOCATION_SERVICES
    
16. prefs:root=ACCOUNT_SETTINGS
    
17. prefs:root=MUSIC
    
18. prefs:root=MUSIC&path=EQ
    
19. prefs:root=MUSIC&path=VolumeLimit
    
20. prefs:root=General&path=Network
    
21. prefs:root=NIKE_PLUS_IPOD
    
22. prefs:root=NOTES
    
23. prefs:root=NOTIFICATIONS_ID
    
24. prefs:root=Phone
    
25. prefs:root=Photos
    
26. prefs:root=General&path=ManagedConfigurationList
    
27. prefs:root=General&path=Reset
    
28. prefs:root=Sounds&path=Ringtone
    
29. prefs:root=Safari
    
30. prefs:root=General&path=Assistant
    
31. prefs:root=Sounds
    
32. prefs:root=General&path=SOFTWARE_UPDATE_LINK
    
33. prefs:root=STORE
    
34. prefs:root=TWITTER
    
35. prefs:root=General&path=USAGE
    
36. prefs:root=VIDEO
    
37. prefs:root=General&path=Network/VPN
    
38. prefs:root=Wallpaper
    
39. prefs:root=WIFI
    
40. prefs:root=INTERNET_TETHERING

复制代码

使用方法： 

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

复制代码

然而不幸的是，ios 5.1之后系统不再支持这些url跳转调用到系统。

Yep, saw this (and many more), even implemented it in a test application. Really need to get the definative word from APPL, but the community concensus opinion is APPL disallowed it in 5.1 after it was publically "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."

所以，要么我们干脆干掉这个功能。要么，变态了。 

1. - (void) showLocationAlert {
   
2. 
   
3.                 if ([CLLocationManager authorizationStatus] != kCLAuthorizationStatusAuthorized) {

5.                         //Check whether Settings page is openable (iOS 5.1 not allows Settings page to be opened via openURL:)
   
6.                         if ([[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:@"prefs:root=LOCATION_SERVICES"]]) {
   
7.                             UIAlertView *alert = [[UIAlertView alloc]initWithTitle:@"Error" message:@"You must enable location service,Turn on location service to allow \"YourApp\" to determine your location" delegate:self cancelButtonTitle:@"Settings" otherButtonTitles:@"Cancel", nil];
