ios 应用内跳转到系统设置界面的最好写法

如下是跳转到系统设置诸多界面的url

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

使用方法：

[[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。

- (void) showLocationAlert {

                if ([CLLocationManager authorizationStatus] != kCLAuthorizationStatusAuthorized) {

                        //Check whether Settings page is openable (iOS 5.1 not allows Settings page to be opened via openURL:)
                        if ([[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:@"prefs:root=LOCATION_SERVICES"]]) {
                            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];
                            [alert show];

                        }
                        else {
                            UIAlertView *alert = [[UIAlertView alloc]initWithTitle:@"Error" message:@"You must enable location service" delegate:self cancelButtonTitle:@"Cancel" otherButtonTitles:@"OK", nil];
                            [alert show];
                        }
                 }
            }



  - (void) alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex  {
          if (buttonIndex == 0) {
                [[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"prefs:root=LOCATION_SERVICES"]];
            }

        }
