Lion style non-modal alert example for iOS

Xcode4 introduced the gray-rounded-square style non-modal alerts that momentarily appear as required. For an example, see 'Build Succeeded'. iirc, this style of non-modal alert is also used elsewhere in Lion.

Now, also iirc, I believe I saw some official iPhone sample code showing how they recommend this effect is achieved in iPhone Apps, but I can't find it again. I'd like to use in my App this to achieve a consistent style.

If someone recalls what I'm talking about, I'd appreciate a link. Tha开发者_StackOverflow中文版nks.

I think you're talking about the bezel notification style? On iOS, I know SSToolkit has support for such a display (under HUD View).

Another way: This uses MBProgressHUD and provides sample code.

I think you can do it using a momentary UIActivityIndicator. Something like this

EDIT: or this

EDIT: The idea is the same, a custom activity indicator. The above answer gives you some more specific links to your problem. But well it is an activity indicator you're looking for.
