Hide custom ViewTableCell Button for a specific cell - ios

Question

I'm facing a problem with a UITableViewCell.
When I generate my tableCells, I check if a value is equal to something and if so, I hide a custom button I made in my prototype cell. The problem is, the button with the identifier I hide is hidden in every Cell and not the current one only...
I looked around but can't find something to do... Could you help ? Here's my code, look at the line if currentPost.valueForKey... == "noLink". Thanks !
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell{
var cell = tableView.dequeueReusableCellWithIdentifier("postCell", forIndexPath: indexPath) as! PostTableViewCell
var currentCell = indexPath
var currentPost = post[indexPath.row]
var currentUser = followedInfo[currentPost.valueForKey("userID") as! String]
cell.username.contentHorizontalAlignment = UIControlContentHorizontalAlignment.Left
cell.userProfil.layer.cornerRadius = 0.5 * cell.userProfil.bounds.size.width
cell.username.setTitle(currentUser?.valueForKey("username") as? String, forState: UIControlState.Normal)
cell.postArtist.text = currentPost.valueForKey("artistName") as? String
cell.postDescription.text = currentPost.valueForKey("postDescription") as? String
cell.postTitle.text = currentPost.valueForKey("songName") as? String
cell.postTime.text = "7J"
cell.postDescription.sizeToFit()
if currentPost.valueForKey("itunesLink") as? String == "noLink" {
cell.postItunes.hidden = true;
}else{
cell.postItunes.addTarget(self, action: "getToStore:", forControlEvents: .TouchUpInside)
}
if currentPost.valueForKey("previewLink") as? String == "noPreview" {
cell.postPlay.alpha = 0;
}else{
cell.postPlay.addTarget(self, action: "getPreview:", forControlEvents: .TouchUpInside)
}
if currentPost.valueForKey("location") as? String == "noLocalisation" {
cell.postLocation.text = "Inconnu"
}else{
cell.postLocation.text = currentPost.valueForKey("location") as? String
}
if currentUser?.valueForKey("profilePicture")! != nil{
var pictureFile: AnyObject? = currentUser?.valueForKey("profilePicture")!
pictureFile!.getDataInBackgroundWithBlock({ (imageData, error) -> Void in
var theImage = UIImage(data: imageData!)
cell.userProfil.image = theImage
})
}
if currentPost.valueForKey("coverLink") as? String == "customImage" {
var profilPictureFile: AnyObject? = currentPost.valueForKey("postImage")
profilPictureFile!.getDataInBackgroundWithBlock { (imageData , imageError ) -> Void in
if imageError == nil{
let image = UIImage(data: imageData!)
cell.postPicture.image = image
}
}
}else{
if currentPost.valueForKey("coverLink") as? String == "noCover"{
var cover = UIImage(named: "noCover")
cell.postPicture.image = cover
}else{
var finalURL = NSURL(string: currentPost.valueForKey("coverLink") as! String)
let request: NSURLRequest = NSURLRequest(URL: finalURL!)
NSURLConnection.sendAsynchronousRequest(request, queue: NSOperationQueue.mainQueue(), completionHandler: {(response: NSURLResponse!,data: NSData!,error: NSError!) -> Void in
if error == nil {
var image = UIImage(data: data)
cell.postPicture.image = image
}
else {
println("Error: \(error.localizedDescription)")
}
})
}
}
return cell;
}

You are not setting the bottom back to visible if you want it to show, because you are reusing the cell the last setup is part of the cell, so as soon as you set it to hidden to true it will still hidden until you set hidden back to false, the best way to use reusable cell is to always set all the options to what you want to be for that cell to avoid the setting to be as the old cell.
if currentPost.valueForKey("itunesLink") as? String == "noLink" {
cell.postItunes.hidden = true;
}else{
cell.postItunes.hidden = false;
cell.postItunes.addTarget(self, action: "getToStore:", forControlEvents: .TouchUpInside)
}
