iOS Information Button
提问by Randolph Levant
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?
在许多 iPhone 应用程序上，我看到一个蓝色的圆形小按钮，单击该按钮时会显示有关该应用程序的信息。这是内置在 iOS SDK 中的东西，还是只是带有自定义图像的自定义按钮？

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.
您可以通过放置一个按钮（圆形按钮）并将其类型更改为深色或浅色信息按钮来在 Interface Builder 中制作信息按钮。
You can also crate an info button programmatically like this:
您还可以像这样以编程方式创建信息按钮：
UIButton *infoButton = [UIButton buttonWithType:UIButtonTypeInfoDark];

It's in the Interface Builder. Place a Round-Rect button and change the type to "Info Light" or "Info Dark"
它在界面生成器中。放置一个 Round-Rect 按钮并将类型更改为“Info Light”或“Info Dark”
Then you simply link it to creating a new subview in which you place all the information about the app or whatever else you would like to put there.
然后您只需将它链接到创建一个新的子视图，您可以在其中放置有关应用程序的所有信息或您想放在那里的任何其他信息。
