EAIntroView is an iOS library that makes it straightforward to add introductory walkthrough screens to an iPhone or iPad app. These are the swipeable welcome pages that many apps show to new users when they first open the app, explaining what the app does before handing control over. The library is built around two main pieces. The first is EAIntroPage, which represents a single slide in the walkthrough. Each page can have a background image, a title, a description, an icon, and custom fonts and colors for the text. You can also supply your own completely custom view for a page if the default layout does not fit your needs, including views loaded from a nib file. The second piece is EAIntroView itself, which holds all the pages and handles the transitions between them. Beyond basic page content, the library offers a range of options for the overall experience. You can let users swipe past the last page to dismiss the walkthrough, or close it with a single tap anywhere. There is support for a skip button, a custom page indicator dot control, a pinned title view that stays visible across all pages, and iOS parallax motion effects on background images. Callbacks let your app respond when the intro finishes or when a specific page appears. Adding the library to an Xcode project can be done through CocoaPods or Carthage, which are standard iOS dependency managers, or by copying the source files in manually. It also works with Interface Builder and Storyboard setups, so you can configure an EAIntroView visually rather than purely in code. The README includes short code examples showing how to build pages, assemble the intro view, and display it inside an existing view controller. A demo project is included in the repository with more elaborate examples, including pages with animations and interactive elements.
