UIImageView Array not showing contents? - ios

Question

I have an array of UIImageViews that I want to display to the screen. However, I can't seem to be able to do so. I declared my array of UIImageViews like so:
class EventCell: UITableViewCell, CellDelegate{
#IBOutlet var eventName: UILabel!
#IBOutlet var eventLocation: UILabel!
#IBOutlet var attendeesImages: [UIImageView]!
}
And I have a function that displays the EventCell contents like so:
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
//Dequeue a "reusable" cell
let cell = tableView.dequeueReusableCellWithIdentifier(eventCellIdentifier) as! EventCell
setCellContents(cell, indexPath: indexPath)
return cell
}
//Set contents of Event Cell.. self.events is a global array
//which have information that EventCell objects need to display
func setCellContents(cell:EventCell, indexPath: NSIndexPath!){
let item = self.events[indexPath.section]
var count = 0
cell.eventName.text = item.eventName()
cell.eventLocation.text = item.eventLocation()
cell.attendeesImage.removeAll(keepCapacity: false)//Remove old images before adding new
for value in item.attendeesImage {
let newImageView = UIImageView(image : value)
newImageView.clipsToBounds = true
newImageView.layer.cornerRadius = newImageView.frame.size.width / 2
cell.attendeesImage.append(newImageView)
println("Count inside: \(cell.attendeesImage.count)")
}
}
I printed out the count of the cell.attendeesImage to ensure that no extraneous images were being added and it seemed to prove correct. However, I have no idea why my images are not displaying. I made sure to hook the cell.attendeesImage as an IBCollection in my Storyboard (since it is an Array) in my EventCell. Any ideas for why this isn't showing up? Thanks!

Answer 1

You are using wrong the collection outlet "attendeesImages".
When the view is loaded, the array attendeesImages are created and initialized with the image views you have created in interface builder. But then, if you remove all that references, you have lost the link between the outlets and the real views. The new image views you are creating are not the ones in the cell. They are still subviews of the cell, but now you have not a iboutlet references to them.
The solution: don't remove the values from the array. Just modify the image in each image view.
