从检索到的 Firebase 数据在 TableView 上快速设置图像

Question

So the way I struct my retrieved data is by;

struct framePic { let imagedB : Data! let pricedB : String! }

I've managed to retrieve the data but I dont know how to set image on tableView? I've managed to figure it out with a label... but not with image?

this is the code for the cell in the table;

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {


    let cell: RowCellTableView = myTableView.dequeueReusableCell(withIdentifier: "cell") as! RowCellTableView

     // sets label
    cell.priceView.text = framePics[indexPath.row].pricedB

    // set image on UIimageView???
    --- I dont know how to add this? I need somehow to get the list of only the images???  I believe if I had the array variable like; imageFiles[] I could have done;
imageFiles[indexPath.row].getDataInBackground... But in my case I use struct so how am I supposed to do this in this case?

the RowCellTableView just contains;

  @IBOutlet weak var imageView: UIImageView!
  @IBOutlet weak var priceView: UILabel!

Answer 1

In your struct you have:

struct framePic { 
   let imagedB : Data! 
   let pricedB : String! 
}

Try to convert the imagedB to UIImage like this:

var imageUIImage: UIImage = UIImage(data: imageData)

So your implementation would be like this:

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {


    let cell: RowCellTableView = myTableView.dequeueReusableCell(withIdentifier: "cell") as! RowCellTableView

     // sets label
    cell.priceView.text = framePics[indexPath.row].pricedB

    // convert imageData to UIImage
    var imageUIImage: UIImage = UIImage(data: framePics[indexPath.row].imagedB)

    // apply image to UIImageView
    cell.imageView.image = imageUIImage

    return cell
}

Answer 2

cell.imageView.image = someImage
