ios 界面跳转设置

如下是跳转到系统设置诸多界面的url 

Key代码  

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  

使用方法： 

Objective-c代码  

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

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。 
Objective-c代码  

1. - (void) showLocationAlert {  
2.   
3.                 if ([CLLocationManager authorizationStatus] != kCLAuthorizationStatusAuthorized) {  
4.   
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];  
8.                             [alert show];  
9.   
10.                         }  
11.                         else {  
12.                             UIAlertView *alert = [[UIAlertView alloc]initWithTitle:@"Error" message:@"You must enable location service" delegate:self cancelButtonTitle:@"Cancel" otherButtonTitles:@"OK", nil];  
13.                             [alert show];  
14.                         }  
15.                  }  
16.             }  
17.   
18.   
19.   
20.   - (void) alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex  {  
21.           if (buttonIndex == 0) {  
22.                 [[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"prefs:root=LOCATION_SERVICES"]];  
23.             }  
24.   
25.         }
