Swift link Image from Parse array using segues to secondViewController

Question

Here is my code, i am trying to use the \"prepareForSegue\" function to send an image from tableViewController (firstViewController) to my detailedViewController (secondViewCont

Answer 1

It looks like you should define a UIImageView instead of a UIImage in secondViewController. Your detailImageView will need to be of type UIImageView. The way you have it written, it is of type UIImage.

In secondViewController, replace

var detailImageView = UIImage()

with

var detailImageView = UIImageView()

Then change:

// its this line below....i think
detailImage.image = detailImageView

to

// its this line below....i think
detailImage.image = detailImageView.image

To handle the image sending from the table view cell to the second view controller will require grabbing the image from the selected cell. This would look something like this in your prepareForSegue:

if let myIndexPath = tableView.indexPathForSelectedRow? {
    let cell = self.tableView.cellForRowAtIndexPath(myIndexPath)
    eventDetailVC.detailImageView.image = cell.postedEventImage.image 
}

Your other assignments in viewDidLoad in secondViewController are also a bit unusual. You appear to be assigning the text values from UILabels based on how you are naming them. If a variable is a UILabel than having it named somethingLabel is appropriate. However, if the type is a String, which they are based on your variable assignments, than having it named somethingLabel can be a source of confusion.

Hers the save code i think you wanted to see...

    override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
    let myCell = tableView.dequeueReusableCellWithIdentifier("cell", forIndexPath: indexPath) as! EventsCell

    postedImages[indexPath.row].getDataInBackgroundWithBlock { (data, error) -> Void in

        if let downloadedImage = UIImage(data: data!) {

            myCell.postedEventImage.image = downloadedImage
        }
    }
    myCell.eventName.text = postedEvents[indexPath.row]
    myCell.eventStart.text = postedStart[indexPath.row]
    myCell.eventPrice.text = postedPrices[indexPath.row]

    return myCell
}

and then there is also this code on how i append to my postImages array

     if let objects = objects {
                for object in objects {

                    self.postedImages.append(object.objectForKey("Image") as! PFFile)

                    self.tableView.reloadData()
                }
