TableView Swift中的UIImage视图

Question

im doing tableview controller with images and i used this code

override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
    var cell = self.tableView.dequeueReusableCellWithIdentifier("cell") as UITableViewCell

    var program : Program

    program = programy[indexPath.row]

    cell.textLabel?.text = program.name
    cell.accessoryType = UITableViewCellAccessoryType.DisclosureIndicator

    var imageName = UIImage(named: programy[indexPath.row])
    cell.imageView?.image = imageName

and im getting error in

var imageName = UIImage(named: programy[indexPath.row])

Cannot invoke 'init' with an argument list of type (named $T5)

Answer 1

您已经在上面的代码中从数组中获得了图像的名称，因此您可能也想将其用于UIImage安装：

var imageName = UIImage(named: program.name) 

Answer 2

We can see that programy contains Program types. UIImage(named: String) expects a String so you need to give that Program.name or Program.category . Try this

var imageName = UIImage(named: program.name)
