使用cell.imageView.image的不同大小的图像.迅速

是否可以将所有图像设置为相同的尺寸？我试过使用cell.imageView？.frame.size.width = something.但是,它不起作用.有什么建议？谢谢.

func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
    let cell: UITableViewCell = UITableViewCell(style: UITableViewCellStyle.Subtitle, reuseIdentifier: "Cell")
    cell.imageView!.layer.cornerRadius = 20
    cell.imageView!.clipsToBounds = true
    let imageData = try! resultsImageFileArray[indexPath.row].getData()
    let image = UIImage(data: imageData)
    cell.imageView?.image = image

    cell.textLabel?.text = self.resultsNameArray[indexPath.row]
    cell.detailTextLabel?.text = self.message3Array[indexPath.row]

    return cell
}

使用UITableViewCell时,无法更改cell.imageView字段的属性,因为在这种情况下,imageView是只读属性.在这种情况下实现结果的最简单方法是创建UITableViewCell的子类,并使用它来自定义layoutSubviews方法中所需的内容,例如：

class CustomTableViewCell: UITableViewCell {

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

    override func setSelected(selected: Bool, animated: Bool) {
        super.setSelected(selected, animated: animated)
    }

    // Here you can customize the appearance of your cell
    override func layoutSubviews() {
        super.layoutSubviews()
        // Customize imageView like you need
        self.imageView?.frame = CGRectMake(10,0,40,40)
        self.imageView?.contentMode = UIViewContentMode.ScaleAspectFit
        // Costomize other elements
        self.textLabel?.frame = CGRectMake(60, 0, self.frame.width - 45, 20)
        self.detailTextLabel?.frame = CGRectMake(60, 20, self.frame.width - 45, 15)
    }
}

在tableView(tableView：UITableView,cellForRowAtIndexPath indexPath：NSIndexPath)函数中,您只能将单元对象创建从UITableViewCell替换为CustomTableViewCell：

func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
    let cell: CustomTableViewCell = CustomTableViewCell(style: UITableViewCellStyle.Subtitle, reuseIdentifier: "Cell")
    cell.imageView!.layer.cornerRadius = 20
    cell.imageView!.clipsToBounds = true
    let imageData = try! resultsImageFileArray[indexPath.row].getData()
    let image = UIImage(data: imageData)
    cell.imageView?.image = image

    cell.textLabel?.text = self.resultsNameArray[indexPath.row]
    cell.detailTextLabel?.text = self.message3Array[indexPath.row]

    return cell
}
