在集合视图中显示两个不同的单元格 - Swift 2.0 iOS [英] Displaying two different cells in a collection view - Swift 2.0 iOS

问题描述

我正在开发一个交易"应用程序，我希望在其中拥有静态数量的单元格.

I'm working on a "trading" application where I would like to have a static number of cells.

加载时，用户会看到 5 个单元格，每个单元格都显示一个标有添加"的标签.

On load, users will see 5 cells, each displaying a label that says "Add."

添加玩家"后，该单元格显示玩家信息，其他 4 个单元格仍显示添加"标签.另一个是添加的，2个单元格有玩家信息，3个有添加"

When a "player" is added, that cell displays the players information, the other 4 cells still display the "Add" label. Another is added, 2 cells have player information, 3 have the "Add"

我玩得很开心.谁能指出我正确的方向?我有自定义标签设置，我认为我的逻辑可能只是关于如何正确执行此操作.

I'm having a hell of a time with this. Can anyone point my in the right direction? I have custom labels setup, I think my logic may just be off on how to perform this correctly.

推荐答案

你需要在你的viewController中继承UICollectionViewDelegate和UICollectionViewDataSource协议，然后你需要实现numberOfItemsInSection 和 cellForItemAtIndexPath 函数.除此之外，您需要在情节提要中创建两种类型的单元格并将它们子类化，在下面的代码中，我将假设您调用 AddedPlayerCell 和 DefaultCell 您的单元格，我会假设每个单元格也有一个名为 labelText 的标签.

You need to subclass the UICollectionViewDelegate and UICollectionViewDataSource protocols in your viewController, then you need to implement the numberOfItemsInSection and cellForItemAtIndexPath functions. Additionally to that you need to create two type of cells in your storyboard and subclass them, in the following code i will suppose that you call AddedPlayerCell and DefaultCell your cells, i will suppose that each cell has a label called labelText too.

let players = ["Player1","Player2"] //players added till now
let numberOfCells = 5

//Here you set the number of cell in your collectionView    
func collectionView(collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
            return max(players.count,numberOfCells);
}

func collectionView(collectionView: UICollectionView, cellForItemAtIndexPath indexPath: NSIndexPath) -> UICollectionViewCell {
            if((indexPath.row + 1) < self.players.count){ //If index of cell is less than the number of players then display the player

                    let cell = collectionView.dequeueReusableCellWithReuseIdentifier("yourIdentifierForAddedPlayerCell", forIndexPath: indexPath) as! AddedPlayerCell
                    cell.labelText.text = self.players[indexPath.row] //Display player
                    return cell;

            }else{//Else display DefaultCell
                    let cell = collectionView.dequeueReusableCellWithReuseIdentifier("yourIdentifierForDefaultCell", forIndexPath: indexPath) as! DefaultCell
                    cell.labelText.text = "Add"
                    return cell;
            }
}
