iOS Information Button

Question

On a number of iPhone applications I'm seeing a little blue circular button that, when clicked on, displays information about the application. Is this something that is built into the iOS SDK, or is it simply a custom button with a custom image?

Answer 1

You can make an info button in Interface Builder by placing a button (a Rounded Button) and changing its type into dark or light info button.

You can also crate an info button programmatically like this:

UIButton *infoButton = [UIButton buttonWithType:UIButtonTypeInfoDark];
