Question

Is it possible to customize the default alert message when the iPhone wants to use users current location. I want to change not only the text but also the default blue screen alert view. Is it possible ?

Thanks.

Answer 1

Not possible. From documentation,

Important: In addition to hardware not being available, the user has
the option of denying an application’s access to location service
data. During its initial uses by an application, the Core Location
framework prompts the user to confirm that using the location service
is acceptable. If the user denies the request, the CLLocationManager
object reports an appropriate error to its delegate during future
requests. You can also check the application’s explicit authorization
status using the authorizationStatus method.

The alert is prompted by Core location framework. We don’t have any control over it.

EDIT : To add up, from this Apple developer forum thread (login required)

That alert is shown in a standard fashion for all applications for
privacy reasons. The user’s current location is sensitive
information, and we want to be sure that they give their informed
consent to any use of it on the device. The way that we do that is by
providing a clear, consistent mechanism for the user to give their
consent. If applications were allowed to override or disable the
alert, then that consistency would be lost.
