解决方案

您无法从此警报中直接回拨。但是，如果用户不允许使用核心位置，则会收到 -locationManager：didFailWithError：，其中 kCLErrorDenied error to your CLLocationManagerDelegate 。

从iOS 4.2开始，您还可以收听 - locationManager：didChangeAuthorizationStatus：或者检查 CLLocationManager 的 authorizationStatus 。这给你一个详细的状态。

I am using GPS in iphone and it show conformation message for use location service. and i want to trap what user select "Allow" or "No". can any one suggest how i do this?

Thank

解决方案

You don't get a direct callback from this alert. However, if the user does not allow Core Location usage, you'll receive a -locationManager:didFailWithError: with a kCLErrorDenied error to your CLLocationManagerDelegate.

Since iOS 4.2, you can also listen to -locationManager:didChangeAuthorizationStatus: or check the authorizationStatus of CLLocationManager. This gives you a detailed status.
