Can't add circular mask in tableView - ios

Question

I am creating a UITableViewCell object and returning it inside cellForRowAtIndexPath function in tableView. I have a UIView in the cell which I want to make circular. Using the code from this link, I had written following code:
override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell = UITableViewCell()
let containerDP = UIView()
containerDP.backgroundColor = UIColor.redColor()
// some code
let firstLetter = UILabel()
firstLetter.backgroundColor = UIColor.yellowColor()
firstLetter.text = (data[indexPath.row].UserObject.FirstName! as String).uppercaseString[0]
firstLetter.font = UIFont(name: firstLetter.font.fontName, size: 50)
firstLetter.adjustsFontSizeToFitWidth = true
firstLetter.textAlignment = NSTextAlignment.Center
firstLetter.layer.cornerRadius = firstLetter.frame.size.width / 2;
firstLetter.clipsToBounds = true
containerDP.addSubview(firstLetter)
firstLetter.snp_makeConstraints { (make) -> Void in
make.center.equalTo(containerDP)
make.edges.equalTo(containerDP).inset(UIEdgeInsetsMake(10, 10, 10, 10))
}
// some code
return cell
}
But there is still no circular mask:

Answer 1

Try this :
override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell = UITableViewCell()
let containerDP = UIView()
containerDP.backgroundColor = UIColor.redColor()
// some code
let firstLetter = UILabel()
firstLetter.backgroundColor = UIColor.yellowColor()
firstLetter.text = (data[indexPath.row].UserObject.FirstName! as String).uppercaseString[0]
firstLetter.font = UIFont(name: firstLetter.font.fontName, size: 50)
firstLetter.adjustsFontSizeToFitWidth = true
firstLetter.textAlignment = NSTextAlignment.Center
firstLetter.layer.cornerRadius = firstLetter.frame.size.width / 2;
firstLetter.layer.masksToBounds = true
firstLetter.clipsToBounds = true
containerDP.addSubview(firstLetter)
firstLetter.snp_makeConstraints { (make) -> Void in
make.center.equalTo(containerDP)
make.edges.equalTo(containerDP).inset(UIEdgeInsetsMake(10, 10, 10, 10))
}
// some code
return cell
}

Answer 2

Use dequeueReusableCellWithIdentifier for tablewView cell creating and caching
Make subview setups for tableViewCell in awakeFromNib method
With clipsToBounds = true it should work

Answer 3

first you should create a customtableviewCell class for your tableview.
then make IBOutlet connection to your cutomtablviewCell
then #import your customtablviewCell to your tableviewController
then inside the cellForRowAtIndexPath method(I'm well in objectiveC, not in swift) call to your cutomTableviewcell like below
customTableviewCell *cell = [your code here];
after that do your styles like
cell.fisrtLetter.layer.cornerRadius = cell.firstletter.frame.size.width/2;
cell.firstLetter.layer.masksToBounds = true;
please get the idea.
