Swift滑动导航表视图

Question

我正在尝试在swift中的不同tableViewControllers之间进行滑动导航.我设法使用viewControllers使用以下代码:

import UIKit

class ViewController: UIViewController {

@IBOutlet weak var scrollView: UIScrollView!

override func viewDidLoad() {
    super.viewDidLoad()

}

var scrollViewAdded = false

override func viewDidLayoutSubviews() {

    super.viewDidLayoutSubviews()

    if !scrollViewAdded {

        self.loadSrollView()

        self.scrollViewAdded = true
    }
}


func loadSrollView() {

    self.scrollView.pagingEnabled = true

    let vc0 = self.storyboard?.instantiateViewControllerWithIdentifier("ViewController0")

    self.addChildViewController(vc0!)
    self.scrollView.addSubview(vc0!.view)
    vc0!.didMoveToParentViewController(self)


    let vc1 = self.storyboard?.instantiateViewControllerWithIdentifier("ViewController1")

    var frame1 = vc1!.view.frame
    frame1.origin.x = self.view.frame.size.width
    vc1!.view.frame = frame1

    self.addChildViewController(vc1!)
    self.scrollView.addSubview(vc1!.view)
    vc1!.didMoveToParentViewController(self)


    let vc2 = self.storyboard?.instantiateViewControllerWithIdentifier("ViewController2")

    var frame2 = vc2!.view.frame
    frame2.origin.x = self.view.frame.size.width * 2
    vc2!.view.frame = frame2

    self.addChildViewController(vc2!)
    self.scrollView.addSubview(vc2!.view)
    vc2!.didMoveToParentViewController(self)


    let vc3 = self.storyboard?.instantiateViewControllerWithIdentifier("ViewController3")

    var frame3 = vc3!.view.frame
    frame3.origin.x = self.view.frame.size.width * 3
    vc3!.view.frame = frame3

    self.addChildViewController(vc3!)
    self.scrollView.addSubview(vc3!.view)
    vc3!.didMoveToParentViewController(self)


    self.scrollView.contentSize = CGSizeMake(self.view.frame.size.width * 4, self.view.frame.size.height - 66)
}

}

我认为我可以通过tableviewcontrollers替换viewcontrollers来调整它,但它不起作用.谁知道怎么做？

Answer 1

以下是在项目中使用XLPagerTabStrip库的步骤:

步骤1:在Storyboard(假定为初始VC)上拖动VC并在此VC上拖动Container View(完全占用VC).拖动另一个空VC(将其类定义为"myPagerStrip",将在下一步中创建).现在控制从容器视图拖动并选择嵌入并定义此Storyboard Embed segue的标识符为"showMyPagerStrip"

步骤2:使用以下代码创建名为"myPagerStrip.swift"的新Swift文件: -

注意:如果对下面的代码有任何疑问,请参考上面已经提到的github链接,一切都在那里解释.

import XLPagerTabStrip

class myPagerStrip: ButtonBarPagerTabStripViewController {


    override func viewDidLoad() {


        settings.style.buttonBarBackgroundColor = UIColor.yellowColor()


        // selected bar view is created programmatically so it's important to set up the following 2 properties properly
        settings.style.selectedBarBackgroundColor = UIColor.blackColor()
        //settings.style.selectedBarHeight: CGFloat = 5

        // each buttonBar item is a UICollectionView cell of type ButtonBarViewCell
        settings.style.buttonBarItemBackgroundColor =  UIColor.redColor()
        settings.style.buttonBarItemFont = UIFont.systemFontOfSize(18)
        // helps to determine the cell width, it represent the space before and after the title label
       // settings.style.buttonBarItemLeftRightMargin: CGFloat = 8
        settings.style.buttonBarItemTitleColor =  UIColor.whiteColor()
        // in case the barView items do not fill the screen width this property stretch the cells to fill the screen
        settings.style.buttonBarItemsShouldFillAvailiableWidth = true

        changeCurrentIndexProgressive = { (oldCell: ButtonBarViewCell?, newCell: ButtonBarViewCell?, progressPercentage: CGFloat, changeCurrentIndex: Bool, animated: Bool) -> Void in
            guard changeCurrentIndex == true else { return }

            oldCell?.label.textColor = UIColor(white: 1, alpha: 0.6)
            newCell?.label.textColor = .whiteColor()

            if animated {
                UIView.animateWithDuration(0.1, animations: { () -> Void in
                    newCell?.transform = CGAffineTransformMakeScale(1.0, 1.0)
                    oldCell?.transform = CGAffineTransformMakeScale(0.8, 0.8)
                })
            }
            else {
                newCell?.transform = CGAffineTransformMakeScale(1.0, 1.0)
                oldCell?.transform = CGAffineTransformMakeScale(0.8, 0.8)
            }
        }

        super.viewDidLoad()
    }


    override func viewControllersForPagerTabStrip(pagerTabStripController: PagerTabStripViewController) -> [UIViewController] {


        let child_1 = UIStoryboard(name: "Main", bundle: nil).instantiateViewControllerWithIdentifier("tableViewOne") // First Table View

        let child_2 = UIStoryboard(name: "Main", bundle: nil).instantiateViewControllerWithIdentifier("tableViewTwo") // Second Table View

        let child_3 = UIStoryboard(name: "Main", bundle: nil).instantiateViewControllerWithIdentifier("tableViewThree") // Third Table View

        let childVC = [child_1,child_2, child_3]

        return childVC

    }

    override func reloadPagerTabStripView() {
        super.reloadPagerTabStripView()
    }

}

步骤3:在Storyboard上再拖动3个VC并创建3个Cocoa类文件,即tableViewOne.swift,tableViewTwo.swift和tableViewThree.swift,其中Storyboard ID为"tableViewOne","tableViewTwo","tableViewThree".//(如上所述) child_1,child_2和child_3的代码)

注意:假设所有3个tableView或所需的tableView都设置了所需的数据.

步骤4:在每个tableViews中继承"IndicatorInfoProvider"(在步骤5之后执行),即

class tableViewOne: UIViewController,IndicatorInfoProvider

步骤5:在每个文件中导入XLPagerTabStrip,并在每个tableView中添加以下功能: -

func indicatorInfoForPagerTabStrip(pagerTabStripController: PagerTabStripViewController) -> IndicatorInfo {
        return IndicatorInfo(title: "My Child title 1")
    }

现在,你已经完成了.只需在模拟器或实际设备中运行项目.:)

如果表视图有问题,以下是tableViewOne.swift的代码供参考: -

import UIKit
import XLPagerTabStrip

class tableViewOne: UIViewController,IndicatorInfoProvider {

    @IBOutlet var tableView: UITableView!
        var dummyData = ["data 0","data 001","data try"]

    override func viewDidLoad() {
        super.viewDidLoad()

    }

    func indicatorInfoForPagerTabStrip(pagerTabStripController: PagerTabStripViewController) -> IndicatorInfo {
        return IndicatorInfo(title: "My Child title 1")
    }

}
extension tableViewOne: UITableViewDataSource, UITableViewDelegate {

    func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int
    {
        return dummyData.count
    }

    func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell
    {
        let cell = tableView.dequeueReusableCellWithIdentifier("Cell")! as UITableViewCell

        cell.textLabel!.text = dummyData[indexPath.row]

        return cell;
    }

}
