ios 8 Swift - 带嵌入式CollectionView的TableView-Java 学习之路

我对iOS编程比较陌生，尝试过一些东西，但无济于事 .

我想把 CollectionView 放在 TableViewCell 里面 . 我可以单独编码，但不了解如何设置和引用 TableViewCell 中的每个 CollectionView .

我找到了这个教程，http://ashfurrow.com/blog/putting-a-uicollectionview-in-a-uitableviewcell/，它展示了如何在Objective-C中完成它，但我一直在努力使用Obj-C .

有没有人知道Swift教程还是可以提供帮助？我正在创建一个简单的项目/代码，我将很快发布，以尝试和协助 .

我刚刚找到了上述链接的快速版本 . 我现在正在解决这个问题，但似乎过于复杂，修改了AppDelegate .

创建一个通常的UITableView并在你的UITableViewCell中创建UICollectionView . 您的collectionView委托和数据源应符合该UITableViewCell .

试试看吧

在您的ViewController中

// Global Variable
var tableView: UITableView!

override func viewDidLoad() {
    super.viewDidLoad()

tableView = UITableView(frame: self.view.bounds)
    tableView.delegate = self
    tableView.dataSource = self
    self.view.addSubview(tableView)

    tableView.registerClass(TableViewCell.self, forCellReuseIdentifier: "TableViewCell")
    tableView.registerClass(UITableViewCell.self, forCellReuseIdentifier: "NormalCell")
}

func numberOfSectionsInTableView(tableView: UITableView) -> Int {
    return 1
}

func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
    return 5
}

func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
    if indexPath.row == 3 {
        var cell: TableViewCell = tableView.dequeueReusableCellWithIdentifier("TableViewCell", forIndexPath: indexPath) as! TableViewCell
        cell.backgroundColor = UIColor.groupTableViewBackgroundColor()
        return cell

    } else {
        var cell: UITableViewCell = tableView.dequeueReusableCellWithIdentifier("NormalCell", forIndexPath: indexPath) as! UITableViewCell
        cell.textLabel?.text = "cell: \(indexPath.row)"

        return cell
    }
}

正如您所看到的，我创建了两个不同的单元格，一个自定义的TableViewCell，仅在行索引为3时返回，而在其他索引中返回基本的UITableViewCell .

自定义“TableViewCell”将具有我们的UICollectionView . 所以创建一个UITableViewCell子类并记下下面的代码 .

import UIKit

class TableViewCell: UITableViewCell, UICollectionViewDataSource, UICollectionViewDelegate {

var collectionView: UICollectionView!

override init(style: UITableViewCellStyle, reuseIdentifier: String?) {
    super.init(style: style, reuseIdentifier: reuseIdentifier)

    let layout = UICollectionViewFlowLayout()
    layout.scrollDirection = UICollectionViewScrollDirection.Horizontal

    collectionView = UICollectionView(frame: self.bounds, collectionViewLayout: layout)
    collectionView.delegate = self
    collectionView.dataSource = self
    collectionView.registerClass(UICollectionViewCell.self, forCellWithReuseIdentifier: "CollectionViewCell")
    collectionView.backgroundColor = UIColor.clearColor()

    self.addSubview(collectionView)
}

required init(coder aDecoder: NSCoder) {
    super.init(coder: aDecoder)
}

// MARK: UICollectionViewDataSource
func numberOfSectionsInCollectionView(collectionView: UICollectionView) -> Int {
    return 1
}


func collectionView(collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
    return 10
}

func collectionView(collectionView: UICollectionView, cellForItemAtIndexPath indexPath: NSIndexPath) -> UICollectionViewCell {
    let cell: UICollectionViewCell = collectionView.dequeueReusableCellWithReuseIdentifier("CollectionViewCell", forIndexPath: indexPath) as! UICollectionViewCell
    if indexPath.row%2 == 0 {
        cell.backgroundColor = UIColor.redColor()
    } else {
        cell.backgroundColor = UIColor.yellowColor()
    }

    return cell
}
}

希望能帮助到你 .
