Question

我有一个包含多个部分的表格视图。在第1部分中，我想要4个具有固定高度的tableview单元格，而在所有其他部分中，我希望具有动态高度的tableview单元格。问题是，当我填充表格视图时，> 0部分中的动态单元格单元未根据内容调整大小。

对于动态高度，我在viewDidLoad视图控制器委托中使用了以下几行。

tableView.estimatedRowHeight = 83
tableView.rowHeight = UITableViewAutomaticDimension

和其他方法是：

func numberOfSections(in tableView: UITableView) -> Int {
    return configRowsInSection.count
}

func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int{
    //configRowsInSection = listingsDetail.Specifications[IndexPath.sec].Configurations
    switch (section) {
       case 0:
          return 4
       default: 
        return Configurations.count
}

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
    if indexPath.section == 0 {
        if indexPath.row == 0 {
            let cell = tableView.dequeueReusableCell(withIdentifier: "BannerCell", for: indexPath) as! BannerCell
            cell.setCollectionViewDataSourceDelegate(self, forRow: indexPath.row)
            cell.collectionViewOffset = storedOffsets[indexPath.row] ?? 0
            //addPageControl(cell.collectionView)
            
        }
        else if indexPath.row == 1 {
            let cell = tableView.dequeueReusableCell(withIdentifier: "DetailCell", for: indexPath) as! DetailCell
            cell.Model.text = formatTitle(listingDetail: listingsDetail) 
            cell.SerialNumber.text = "Serial# " + listingsDetail.SerialNumber
        }
        else if indexPath.row == 2{
            let cell = tableView.dequeueReusableCell(withIdentifier: "PriceCell", for: indexPath) as! PriceCell
            cell.Price.text = "PRICE  "+listingsDetail.AskingPrice!
        }
        else if indexPath.row == 3 {
            let cell = tableView.dequeueReusableCell(withIdentifier: "HighlightCell", for: indexPath) as! HighlightCell
            cell.filterText.text = listingsDetail.filter
            cell.seatsText.text = listingsDetail.seats
            cell.wheelsText.text = listingsDetail.wheels
            cell.hoursText.text = listingsDetail.hours
        }
    }
    else {
        let cell = tableView.dequeueReusableCell(withIdentifier: "SpecificationCell", for: indexPath) as! SpecificationCell
        cell.configValueBig.text = specificationDetail[indexPath.section-1].Configurations[indexPath.row].Desc
    }
    return UITableViewCell()
}

func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
    var rowHeight:CGFloat!
    if indexPath.section == 0 {
        if indexPath.row == 0 {
            rowHeight = 200
        }
        else if indexPath.row == 1 {
            rowHeight = 100
        }
        else if indexPath.row == 2 {
            rowHeight = 70
        }
        else {
            rowHeight = 144
        }
        return rowHeight
    }
    else {
        rowHeight = 83
        //rowHeight = UITableView.automaticDimension (This makes the row height as -1) 
    }
    return rowHeight
}

func tableView(_ tableView: UITableView, estimatedHeightForRowAt indexPath: IndexPath) -> CGFloat {
    return 83
}

处理具有一个具有固定高度的行的部分和具有可变高度的行的其他动态部分的表视图的最佳方法是什么。预先感谢！

Answer 1

请尝试确保第二部分从底部开始具有正确的约束。处理动态高度的最佳方法是使用UITableView.automaticDimension

func numberOfSections(in tableView: UITableView) -> Int {
    return configRowsInSection.count
}

func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int{
    //configRowsInSection = listingsDetail.Specifications[IndexPath.sec].Configurations
    switch (section) {
       case 0:
          return 4
       default: 
        return Configurations.count
}

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
    if indexPath.section == 0 {
        if indexPath.row == 0 {
            let cell = tableView.dequeueReusableCell(withIdentifier: "BannerCell", for: indexPath) as! BannerCell
            cell.setCollectionViewDataSourceDelegate(self, forRow: indexPath.row)
            cell.collectionViewOffset = storedOffsets[indexPath.row] ?? 0
            //addPageControl(cell.collectionView)
            
        }
        else if indexPath.row == 1 {
            let cell = tableView.dequeueReusableCell(withIdentifier: "DetailCell", for: indexPath) as! DetailCell
            cell.Model.text = formatTitle(listingDetail: listingsDetail) 
            cell.SerialNumber.text = "Serial# " + listingsDetail.SerialNumber
        }
        else if indexPath.row == 2{
            let cell = tableView.dequeueReusableCell(withIdentifier: "PriceCell", for: indexPath) as! PriceCell
            cell.Price.text = "PRICE  "+listingsDetail.AskingPrice!
        }
        else if indexPath.row == 3 {
            let cell = tableView.dequeueReusableCell(withIdentifier: "HighlightCell", for: indexPath) as! HighlightCell
            cell.filterText.text = listingsDetail.filter
            cell.seatsText.text = listingsDetail.seats
            cell.wheelsText.text = listingsDetail.wheels
            cell.hoursText.text = listingsDetail.hours
        }
    }
    else {
        let cell = tableView.dequeueReusableCell(withIdentifier: "SpecificationCell", for: indexPath) as! SpecificationCell
        cell.configValueBig.text = specificationDetail[indexPath.section-1].Configurations[indexPath.row].Desc
    }
    return UITableViewCell()
}

func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
    var rowHeight:CGFloat!
    if indexPath.section == 0 {
        if indexPath.row == 0 {
            rowHeight = 200
        }
        else if indexPath.row == 1 {
            rowHeight = 100
        }
        else if indexPath.row == 2 {
            rowHeight = 70
        }
        else {
            rowHeight = 144
        }
        return rowHeight
    }
   
    return UITableView.automaticDimension
}

func tableView(_ tableView: UITableView, estimatedHeightForRowAt indexPath: IndexPath) -> CGFloat {
    return UITableView.automaticDimension
}

Answer 2

对于cellForRowAtIndexPath中的所有自定义单元格，我们需要返回单元格：

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
if indexPath.section == 0 {
    if indexPath.row == 0 {
        let cell = tableView.dequeueReusableCell(withIdentifier: "BannerCell", for: indexPath) as! BannerCell
        cell.setCollectionViewDataSourceDelegate(self, forRow: indexPath.row)
        cell.collectionViewOffset = storedOffsets[indexPath.row] ?? 0
        //addPageControl(cell.collectionView)
        return cell
    }
    else if indexPath.row == 1 {
        let cell = tableView.dequeueReusableCell(withIdentifier: "DetailCell", for: indexPath) as! DetailCell
        cell.Model.text = formatTitle(listingDetail: listingsDetail) 
        cell.SerialNumber.text = "Serial# " + listingsDetail.SerialNumber
        return cell
    }
    else if indexPath.row == 2{
        let cell = tableView.dequeueReusableCell(withIdentifier: "PriceCell", for: indexPath) as! PriceCell
        cell.Price.text = "PRICE  "+listingsDetail.AskingPrice!
        return cell
    }
    else if indexPath.row == 3 {
        let cell = tableView.dequeueReusableCell(withIdentifier: "HighlightCell", for: indexPath) as! HighlightCell
        cell.filterText.text = listingsDetail.filter
        cell.seatsText.text = listingsDetail.seats
        cell.wheelsText.text = listingsDetail.wheels
        cell.hoursText.text = listingsDetail.hours
        return cell
    }
}
else {
    let cell = tableView.dequeueReusableCell(withIdentifier: "SpecificationCell", for: indexPath) as! SpecificationCell
    cell.configValueBig.text = specificationDetail[indexPath.section-1].Configurations[indexPath.row].Desc
  return cell
}
return UITableViewCell()

}

func tableView(_ tableView: UITableView, estimatedHeightForRowAt indexPath: IndexPath) -> CGFloat {
return 83

}
