iOS8.0以后有效
定位服务
定位服务有很多APP都有，如果用户关闭了定位，那么，我们在APP里面可以提示用户打开定位服务。点击到设置界面设置，直接跳到定位服务设置界面。代码如下：

//定位服务设置界面NSURL *url = [NSURL URLWithString:@"prefs:root=LOCATION_SERVICES"];if ([[UIApplication sharedApplication] canOpenURL:url]){ [[UIApplication sharedApplication] openURL:url];} |
这样就可以跳到系统设置的定位服务界面啦！我们继续看几个列子。
