Ios 使用不同的数据重用UITableViewCell

我有两个不同数据的数组

var array : [String] = ["getMeals", "getMeasure", "getWorkouts"]
var array2 : [String] = ["getStep", "getStep", "getStep"]

我试图从数组中检索图像，但在不同的收集单元中

func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {

    if indexPath.section == 0{
        let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "WorkoutCollectionCell", for: indexPath) as! WorkoutCollectionCell
        cell.collectionImage.image = UIImage(named: array[indexPath.row])
        return cell
    }else{
        let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "WorkoutCollectionCell", for: indexPath) as! WorkoutCollectionCell
                   cell.collectionImage.image = UIImage(named: array2[indexPath.row])
                   return cell
    }

}

我需要创建另一个UICollectionViewCell，或者我可以使用当前单元格？

您可以使用相同的单元格，代码如下：

func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
    let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "WorkoutCollectionCell", for: indexPath) as! WorkoutCollectionCell
    if indexPath.section == 0{

        cell.collectionImage.image = UIImage(named: array[indexPath.row])

    }else{

        cell.collectionImage.image = UIImage(named: array2[indexPath.row])

    }
 return cell
}

    }else{

        cell.collectionImage.image = UIImage(named: array2[indexPath.row])

    }
 return cell
}

你需要一个像这样的数组

let array  = [["getMeals", "getMeasure", "getWorkouts"],["getStep", "getStep", "getStep"]]

func numberOfSections(in collectionView: UICollectionView) -> Int { 
    return array.count
} 
func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int { 
    return array[section].count 
} 
func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell { 
    let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "WorkoutCollectionCell", for: indexPath) as! WorkoutCollectionCell
    cell.collectionImage.image = UIImage(named: array[indexPath.section][indexPath.row])
    return cell  
}

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

    cell.collectionImage.image = UIImage(named: array[indexPath.section][indexPath.row])
    return cell  
}

简短的回答是“是”，首先将单元格出列，根据您想要的任何条件分配内容，然后返回单元格。简短的回答是“是”，首先将单元格出列，根据您想要的任何条件分配内容，然后返回单元格。但现在我有2个collectionViewCells，其中包含6个图像。2个是什么？您只能使用id

WorkoutCollectionCell

将1出列。您不能将集合单元格用于表格和表格，但现在我有2个集合视图单元格，其中包含6个图像2在哪里？您只能使用id

WorkoutCollectionCell

将1出列，不能将收集单元格用于表，反之亦然
