IOS8 jump to System Settings page

Ios5.1+ after the way to jump setting page is invalid, but in iOS8 Apple has provided a key value allows the app to jump to the setting page, the specific code is as follows:

Nsurl *url = [Nsurl urlwithstring:uiapplicationopensettingsurlstring];

if ([[[UIApplication sharedapplication] Canopenurl:url]) {

[[UIApplication sharedapplication] openurl:url];

}

The actual URL string is@"app-settings:"，当在其后面追加子section（例如"Bluetooth", "GENERAL"），也只能跳到系统设置首页
