这是一个创建于 3582 天前的主题，其中的信息可能已经有所发展或是发生改变。

今天清理了一下磁盤, 更新到 beta 版本的 CocoaPods, 將寫好的項目發佈到 CocoaPods 上去了. \w/

在 CocoaPods 發佈 Swift 項目需要將 Command Line Tools 更新到最新版本:

$ xcode-select --install

更新 CocoaPods 到最新的測試版:

$ gem install cocoapods --pre

在國內使用淘寶源的朋友需要切換到官方源:

$ gem sources -r http://ruby.taobao.org/
$ gem sources -r https://ruby.taobao.org/
$ gem sources -a https://rubygems.org/

由于淘宝镜像这边没有实现 /api 下面的协议，而安装 pre 版本需要这些东西检查依赖，所以如果你需要这类安装需求的时候，请临时切换回官方的 RubyGems 源。

最後發佈 pod:

$ pod trunk push

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.

Installation

With CocoaPods

In your Podfile:

pod 'PRSlideView-Swift'

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()
}
