Question

I am detecting whether the user has accepted the request to use location services in my app, I have a toggle switch in the UI that is dependent on this acceptance. The first time they toggle the switch (on) the request to use location is triggered. I want to know which button they press in that alert. (accept or decline) Right now I’m just toggling it off and making the user press it again (then detect which option they picked).

It is kind of sloppy that way, so I’d like to know if there is a way to detect this specific alert or can’t that be done since it is triggered by the OS, not the application? I haven’t tried it yet, but was thinking I could use the UIAlertView delegate methods for just generic button presses, but was hoping for something more specific.

UPDATE

I was able to get this working by just registering a notification when I trigger the location request (and the authorization prompt is shown). The application is placed in an inactive state (much like pulling down the notification bar). I just trigger a notification when the application becomes active and I’m able to just query the authorization status there and update my UI. I hope this helps anyone else down the line if they want to handle the authorization status on the fly.

Answer 1

There is no way to intercept the alert. There is, however, a method on CLLocationManagerDelegate method called didChangeAuthorizationStatus. That’s probably the closest you can get to intercepting the alert.
