SEPageViewWithNavigationBar 2.1.0

您想在 Podfile 中添加类似以下的内容

target 'MyApp' do
  pod 'SEPageViewWithNavigationBar', '~> 2.1'
end

然后在终端或从 CocoaPods.app 中运行 pod install

或者要测试运行，运行以下命令

pod try SEPageViewWithNavigationBar

SEPageViewWithNavigationBar 2.1.0

SEPageViewWithNavigationBar 是 UIViewController 的一个子类，其中包含 UIPageViewController，并在滑动页面时改变导航栏标题，类似于 Twitter 应用。使用 Swift 编写，需要 iOS 7 或更高版本。

使用方法

代码中使用

只需创建 SEPageViewWithNavigationBar 的实例，并将其视图控制器设置到 viewControllers 属性。注意，SEPageViewWithNavigationBar 应嵌入到 UINavigationController 中。

let storyboard = UIStoryboard(name: "Main", bundle: nil)
let vc1 = storyboard.instantiateViewControllerWithIdentifier("vc1")
let vc2 = storyboard.instantiateViewControllerWithIdentifier("vc2")
let vc3 = storyboard.instantiateViewControllerWithIdentifier("vc3")

let pagedViewController = SEPageViewWithNavigationBar()
pagedViewController.viewControllers = [vc1, vc2, vc3]

self.window?.rootViewController = UINavigationController(rootViewController: pagedViewController)

使用 Storyboard

1) 在 Storyboard 中拖拽一个 UIViewController。

2) 将其放置在包含 UINavigationController 的层级中。

3) 在 Identity Inspector 中将自定义类设置为 SEPageViewWithNavigationBar。

4) 在这个 UIViewController 和那些应该是页面的视图控制器之间添加自定义 segue。

5) 在每个 segue 的 Attributes Inspector 中将自定义类设置为 SEPageViewSegue，并将其身份设置为 SEPage。

配置

SEPageViewWithNavigationBar 允许您更改以下属性

titleLabelFont : UIFont

标题标签的字体，默认值为 UIFont.systemFontOfSize(16)。
titleLabelTextColor : UIColor

标题标签的颜色，默认值为 UIColor.whiteColor()。
pageIndicatorTintColor : UIColor

页面指示器的着色，默认值为 UIColor(white: 1.0, alpha: 0.4)。
currentPageIndicatorTintColor : UIColor

当前页面指示器的着色，默认值为 UIColor.whiteColor()。

自定义

默认情况下，导航栏标题显示当前视图控制器的标题。实际上，SEPageViewWithNavigationBar 中的导航栏标题视图是 UICollectionView，因此您可以通过以下函数定义您自己的 UICollectionViewCell 并根据需要对其进行自定义

setCustomTitle(cellClass cellClass: AnyClass, delegateCallback: ((titleCell: UICollectionViewCell, currentPage: Int) -> (UICollectionViewCell)))

例如，如果您需要在标题标签旁边显示图片

class MyCustomCell: UICollectionViewCell
{
    var textLabel : UILabel!
    var imageView : UIImageView!

    override init(frame: CGRect)
    {
        super.init(frame: frame)

        textLabel = UILabel()
        textLabel.translatesAutoresizingMaskIntoConstraints = false
        textLabel.font = UIFont(name: "HelveticaNeue-Light", size: 20)
        textLabel.textColor = UIColor.whiteColor()
        self.contentView.addSubview(textLabel)

        imageView = UIImageView()
        imageView.translatesAutoresizingMaskIntoConstraints = false
        self.contentView.addSubview(imageView)

        let space1 = UIView()
        space1.translatesAutoresizingMaskIntoConstraints = false
        self.contentView.addSubview(space1)

        let space2 = UIView()
        space2.translatesAutoresizingMaskIntoConstraints = false
        self.contentView.addSubview(space2)

        let views = ["textLabel" : textLabel, "imageView" : imageView, "space1" : space1, "space2" : space2]

        self.contentView.addConstraints(NSLayoutConstraint.constraintsWithVisualFormat("H:|[space1(>=0)][imageView]-4-[textLabel][space2(==space1)]|", options: .DirectionLeftToRight, metrics: nil, views: views))
        self.contentView.addConstraint(NSLayoutConstraint(item: imageView, attribute: .CenterY, relatedBy: .Equal, toItem: self.contentView, attribute: .CenterY, multiplier: 1, constant: 0))
        self.contentView.addConstraint(NSLayoutConstraint(item: textLabel, attribute: .CenterY, relatedBy: .Equal, toItem: self.contentView, attribute: .CenterY, multiplier: 1, constant: 0))
    }

    convenience init()
    {
        self.init(frame:CGRectZero)
    }
}

self.window?.rootViewController = UINavigationController(rootViewController: pagedViewController)

pagedViewController.setCustomTitle(cellClass: MyCustomCell.self) { (titleCell: UICollectionViewCell, pageIndex: Int) -> (UICollectionViewCell) in

    let cell = titleCell as! MyCustomCell

    let titles = ["Explore", "Favorites", "Random"]
    let images = [UIImage(named: "Explore"), UIImage(named: "Favorites"), UIImage(named: "Random")]

    cell.textLabel.text = titles[pageIndex]
    cell.imageView.image = images[pageIndex]

    return cell
}

结果

安装

手动

只需将 SEPageViewWithNavigationBar.swift 拖动到您的项目中即可。
