Then, follow the steps as described in Carthage's README.

Requirements

• iOS 9.0+
• Xcode 10.1+

Basic Usage

To get started, this is a simple usage sample of using the integrated view controller.

import FolioReaderKit

func open(sender: AnyObject) {
    let config = FolioReaderConfig()
    let bookPath = Bundle.main.path(forResource: "book", ofType: "epub")
    let folioReader = FolioReader()
    folioReader.presentReader(parentViewController: self, withEpubPath: bookPath!, andConfig: config)
}

For more usage examples check the Example folder.

Storyboard

To get started, here is a simple example how to use the integrated view controller with storyboards.

import FolioReaderKit

class StoryboardFolioReaderContrainer: FolioReaderContainer {
    required init?(coder aDecoder: NSCoder) {
        super.init(coder: aDecoder)
        
        let config = FolioReaderConfig()
        config.scrollDirection = .horizontalWithVerticalContent
        
        guard let bookPath = Bundle.main.path(forResource: "The Silver Chair", ofType: "epub") else { return }
        setupConfig(config, epubPath: bookPath)
    }
}

Go to your storyboard file, choose or create the view controller that should present the epub reader. In the identity inspector set StoryboardFolioReaderContrainer as class.
