iOS---Invoke the function in the system "settings" (GO)

After installation, the first time you run the software, the system will prompt the user whether to allow the software to obtain the current location, if the user does not allow, then the runtime system will not be prompted to set up, this is inconvenient, there is a solution is to give the user an option to bring up the iphone "Settings" location service option, manually set by the user , call the system "settings" to locate the service-related code as follows:

-(Ibaction) btnsetting: (ID) sender{
Nsurl*url=[nsurl urlwithstring:@ "Prefs:root=location_services"];
[[UIApplication sharedapplication] openurl:url];
}
