昨天用 Swift 重寫了之前的一個開源庫 PRSlideView, 今天整理好發佈到 GitHub 上了.

注: 沒有發佈到 CocoaPods 是因為沒有足夠的磁盤空間安裝新的編譯工具通過 CocoaPods 發佈前驗證. 你可以通過給我捐贈一台最新的頂配 MacBook Pro 以解決這個問題. XD

PRSlideView-Swift

This is the Swift language version of PRSlideView.

General

Slide view with gracefully written UIKit-like methods, delegate and data source protocol. Infinite scrolling supported.

Note: Auto layout not supported due to the special behaviours of UIScrollView. Please use autoresizing mask instead or wrap it with a container view.

Usage

Configure a Slide View

slideView.delegate = self
slideView.dataSource = self
slideView.scrollDirection = .Vertical
slideView.infiniteScrollingEnabled = true
slideView.registerClass(
    PRAlbumPage.self,
    identifier: PRAlbumPage.description()
)

Create a Slide View Page Subclass

import UIKit

public class PRAlbumPage: PRSlideViewPage {
    public private(set) var coverImageView: UIImageView

    required public init(frame: CGRect, identifier: String) {
        self.coverImageView = UIImageView()

        super.init(frame: frame, identifier: identifier)

        let coverImageView = self.coverImageView
        coverImageView.frame = self.bounds
        coverImageView.autoresizingMask = (.FlexibleWidth | .FlexibleHeight)
        coverImageView.contentMode = .ScaleAspectFit
        self.addSubview(coverImageView)
    }

    required public init(coder aDecoder: NSCoder) {
        fatalError("init(coder:) has not been implemented")
    }
}

Use Data Source

// MARK: PRSlideViewDataSource

func numberOfPagesInSlideView(slideView: PRSlideView) -> Int {
    return self.albumData.count
}

func slideView(slideView: PRSlideView, pageAtIndex index: Int) -> PRSlideViewPage {
    let page: PRAlbumPage = slideView.dequeueReusablePageWithIdentifier(PRAlbumPage.description(), index: index) as PRAlbumPage

    let imageName: String = self.albumData[index].stringByAppendingPathExtension("jpg")!
    page.coverImageView.image = UIImage(named: imageName)

    return page
}

Use Delegate

// MARK: PRSlideViewDelegate

func slideView(slideView: PRSlideView, didScrollToPageAtIndex index: Int) {
    self.titleLabel.text = self.albumData[index]
}

func slideView(slideView: PRSlideView, didClickPageAtIndex index: Int) {
    let alertView: UIAlertView = UIAlertView(
        title: "You clicked on an album",
        message: "Title: \(self.albumData[index])",
        delegate: nil,
        cancelButtonTitle: "OK")
    alertView.show()
}

All done! You can check out the code in the demo provided.
