在iOS5以下版本使用以下方法：【IOS5.1+之後不能使用此方法，iOS8的跳轉方法已找到見下方，iOS7的正在摸索，歡迎大家給出觀點意見】

通過URL Scheme的方式打開內置的Settings，代碼如下

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

 

以下是內置的Settings的URL Scheme：

 

About — prefs:root=General&path=About

Accessibility — prefs:root=General&path=ACCESSIBILITY

Airplane Mode On — prefs:root=AIRPLANE_MODE

Auto-Lock — prefs:root=General&path=AUTOLOCK

VPN — prefs:root=General&path=Network/VPN

在iOS8版本使用以下方法：

 

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

iOS7版本目前還沒發現解決辦法，歡迎大家多多討論。。。。。
