iOS - Cannot access UITextView delegate inside a UITableViewCell class

Question

I've found some problems when trying to access the UITableViewDelegate methods, inside an instantiated UITableViewCell class.

I'm trying to access the func textView(_ textView: UITextView, shouldInteractWith URL: URL, in characterRange: NSRange) -> Bool {} and the functions doesn't fire, and I guess that's because I've some issues trying to set the delegate.

The code goes as it follows:

import UIKit
class TableViewCell: UITableViewCell, UITextViewDelegate {

    @IBOutlet var titleLabel: UILabel!
    @IBOutlet var textView: UITextView!
    @IBOutlet var postImageView: UIImageView!


    func textView(_ textView: UITextView, shouldInteractWith URL: URL, in characterRange: NSRange) -> Bool {
        print("link tapped")
        return true
    }

    init() {
        super.init()
        textView.delegate = self
    }

    required init?(coder aDecoder: NSCoder) {
        fatalError("init(coder:) has not been implemented")
    }


    override func awakeFromNib() {
        super.awakeFromNib()
    }

    override func setSelected(_ selected: Bool, animated: Bool) {
        super.setSelected(selected, animated: animated)
    }
}

On the super.init() line this error is shown

TableViewCell.swift - "Must call a designated initializer of the superclass" 'UITableViewCell'

Any tip on how to overpass this ?

Thanks in advance

FINAL EDIT I've done what I really wanted to do. Instead of using the UITextFieldDelegate inside the UITableViewCell Class, I've added the UITextFieldDelegate to the ViewController that uses the cell itself, and on the cell configuration just did: cell.textView.degelate = Self , then I've implemented the delegate function of func textView(_ textView: UITextView, shouldInteractWith URL: URL, in characterRange: NSRange) -> Bool {}

Thanks for answering boys.

I've tried already with convenience init() and it didn't work — Ivan Cantarino, Feb 12 '17 at 23:32
I don't think super.init() is a designated initializer. Try one of the others. I think there may be a super.init(nib:, bundle:) or something similar to that. — Erik, Feb 12 '17 at 23:34
If I try the `super.init(style: UITableViewCellStyle.default, reuseIdentifier: "mainCell")` initialiser, the required init() fatal error is shown. — Ivan Cantarino, Feb 12 '17 at 23:41
This shouldn't be hard to access object delegate properties inside table view cells, I'm missing something that I can't see :/ — Ivan Cantarino, Feb 12 '17 at 23:57

The line that's giving you trouble it not textView.delegate = self but rather super.init(). You'll need to properly call this with a nibName and bundle.

init() {
    super.init(nibName: PutTheStringHere, bundle: PutTheBundleHere)
    textView.delegate = self
}
