Installation

CocoaPods

CocoaPods is a dependency manager for Cocoa projects. You can install it with the following command:

$ gem install cocoapods

CocoaPods 1.1+ is required to build DNSPageView.

To integrate DNSPageView into your Xcode project using CocoaPods, specify it in your Podfile:

source 'https://github.com/CocoaPods/Specs.git'
platform :ios, '8.0'
use_frameworks!

target '<Your Target Name>' do
    pod 'DNSPageView'
end

Then, run the following command:

$ pod install

Manually

If you prefer not to use any of the aforementioned dependency managers, you can integrate DNSPageView into your project manually.

Example

To run the example project, clone the repo, and run DNSPageView.xcodeproj .

Usage

直接使用DNSPageView初始化

// 创建DNSPageStyle，设置样式
let style = DNSPageStyle()
style.isTitleScrollEnable = true
style.isScaleEnable = true

// 设置标题内容
let titles = ["头条", "视频", "娱乐", "要问", "体育" , "科技" , "汽车" , "时尚" , "图片" , "游戏" , "房产"]

// 创建每一页对应的controller
let childViewControllers: [ContentViewController] = titles.map { _ -> ContentViewController in
    let controller = ContentViewController()
    controller.view.backgroundColor = UIColor.randomColor
    return controller
}

let size = UIScreen.main.bounds.size

// 创建对应的DNSPageView，并设置它的frame
// titleView和contentView会连在一起
let pageView = DNSPageView(frame: CGRect(x: 0, y: 64, width: size.width, height: size.height), style: style, titles: titles, childViewControllers: childViewControllers)
view.addSubview(pageView)

使用xib或者storyboard初始化

在xib或者storyboard中拖出2个UIView，让它们分别继承DNSPageTitleView和DNSPageContentView，拖线到代码中

@IBOutlet weak var titleView: DNSPageTitleView!

@IBOutlet weak var contentView: DNSPageContentView!

对DNSPageTitleView和DNSPageContentView进行设置

// 创建DNSPageStyle，设置样式
let style = DNSPageStyle()
style.titleViewBackgroundColor = UIColor.red
style.isShowCoverView = true

// 设置标题内容
let titles = ["头条", "视频", "娱乐", "要问", "体育"]

// 设置默认的起始位置
let startIndex = 2

// 对titleView进行设置
titleView.titles = titles
titleView.style = style
titleView.currentIndex = startIndex

// 最后要调用setupUI方法
titleView.setupUI()


// 创建每一页对应的controller
let childViewControllers: [ContentViewController] = titles.map { _ -> ContentViewController in
    let controller = ContentViewController()
    controller.view.backgroundColor = UIColor.randomColor
    return controller
}

// 对contentView进行设置
contentView.childViewControllers = childViewControllers
contentView.startIndex = startIndex
contentView.style = style

// 最后要调用setupUI方法
contentView.setupUI()

// 让titleView和contentView进行联系起来
titleView.delegate = contentView
contentView.delegate = titleView

使用DNSPageViewManager初始化，再分别对titleView和contentView进行布局

创建DNSPageViewManager

private lazy var pageViewManager: DNSPageViewManager = {
    // 创建DNSPageStyle，设置样式
    let style = DNSPageStyle()
    style.isShowBottomLine = true
    style.isTitleScrollEnable = true
    style.titleViewBackgroundColor = UIColor.clear

    // 设置标题内容
    let titles = ["头条", "视频", "娱乐", "要问", "体育"]

    // 创建每一页对应的controller
    let childViewControllers: [ContentViewController] = titles.map { _ -> ContentViewController in
        let controller = ContentViewController()
        controller.view.backgroundColor = UIColor.randomColor
        return controller
    }

    return DNSPageViewManager(style: style, titles: titles, childViewControllers: childViewControllers)
}()

布局titleView和contentView

// 单独设置titleView的frame
navigationItem.titleView = pageViewManager.titleView
pageViewManager.titleView.frame = CGRect(x: 0, y: 0, width: 180, height: 44)

// 单独设置contentView的大小和位置，可以使用autolayout或者frame
let contentView = pageViewManager.contentView
view.addSubview(pageViewManager.contentView)
contentView.snp.makeConstraints { (maker) in
    maker.edges.equalToSuperview()
}

样式

DNSPageStyle中提供了常见样式的属性，可以按照不同的需求进行设置，包括可以设置初始显示的页面

事件监听

DNSPageView提供了常见事件监听的代理，它属于DNSPageTitleViewDelegate的中的可选属性

/// 如果contentView中的view需要实现某些刷新的方法，请让对应的childViewController遵守这个协议
@objc public protocol DNSPageReloadable: class {
    
    /// 如果需要双击标题刷新或者作其他处理，请实现这个方法
    @objc optional func titleViewDidSelectedSameTitle()
    
    /// 如果pageContentView滚动到下一页停下来需要刷新或者作其他处理，请实现这个方法
    @objc optional func contentViewDidEndScroll()
}
