How do I show the standard spin animation during a CoreLocation lookup on iPhone?

Question

I don't want to just use a UIActivityIndicatorView -- I want the spinning animation that you see in the Maps application while you are doing a CoreLocation lookup.

Do I have to create my own animation, or is there an easy way?

edit: I'm referring to the standard Apple "Maps" application. Specifically I'm referring to the animation that occurs in the button in the UIToolbar at the bottom of the page, when you press the button to find your location.

There are two components to this animation -- first the "button push" animation, and then the spinning "busy" animation. I presume the latter is done with a UIActivityIndicatorView, but I was hoping that the whole thing was packaged together into a single control of some sort.

Answer 1

You might be thinking of the network activity indicator, which can be set like

[UIApplication sharedApplication].networkActivityIndicatorVisible = YES;

EDIT: Thanks for the clarification: The Map app is using a UIBarButtonItem with a UIActivityIndicatorIndicator as the custom view. You can do something along the lines of:

UIActivityIndicatorView *indicator =
    [[UIActivityIndicatorView alloc]
        initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleGray];
UIBarButtonItem *button = [[UIBarButtonItem alloc] initWithCustomView:indicator];
[indicator startAnimating];
[indicator release];

Hey, why don't you just put an indicator view on top of a button and display it only when a location is in progress? I did exactly that and it does work perfectly!
