UITextView not displaying keyboard inside CollectionViewCell - ios

Question

I am experiencing some difficulty in getting a UITextView to display a keyboard when tapped by the User. I am testing my app on a live device and not the simulator, so it is not the common "keyboard in simulator" issue a lot of developers experience.
I believe it might have something to do with the structure of the app.
I have a TableViewController with a cell that contains a CollectionViewController, and the UITextView is inside a CollectionViewCell.
I had this working in the past, but my fix does not appear to be working anymore. (I'm updating this app for the 1st time in 4 years), So I have stripped out all the code relating to other components in the cell and am now working with just this code (In order of "what should be called first):
TableViewCell for statuses:
This bit of code is inside tableView(cellForRowAtIndexPath)
case 5:
let cell = tableView.dequeueReusableCell(withIdentifier: "status") as! StatusTableViewCell
cell.collectionView.event = self.event
cell.collectionView.doLoad()
cell.collectionView.rootView = self
return cell
StatusTableViewCell
This contains the CollectionView which should display a list of "Statuses" (imagine if Facebook was horizontal)
class StatusTableViewCell: UITableViewCell {
var collectionView: StatusView
override init(style: UITableViewCell.CellStyle, reuseIdentifier: String?) {
let layout = UICollectionViewFlowLayout()
layout.scrollDirection = .horizontal
collectionView = StatusView(frame: .zero, collectionViewLayout: layout)
super.init(style: style, reuseIdentifier: reuseIdentifier)
doSetup()
}
required init?(coder aDecoder: NSCoder) {
fatalError("init(coder:) has not been implemented")
}
func doSetup(){
//backgroundColor = .black
addSubview(collectionView)
addConstraints(NSLayoutConstraint.constraints(withVisualFormat: "H:|[v0]|", options: NSLayoutConstraint.FormatOptions(), metrics: nil, views: ["v0": collectionView]))
addConstraints(NSLayoutConstraint.constraints(withVisualFormat: "V:|[v0]|", options: NSLayoutConstraint.FormatOptions(), metrics: nil, views: ["v0": collectionView]))
}
override func awakeFromNib() {
super.awakeFromNib()
// Initialization code
}
override func setSelected(_ selected: Bool, animated: Bool) {
super.setSelected(selected, animated: animated)
// Configure the view for the selected state
}
}
StatusView
This is the bit of code that calls the NewStatusViewCell
func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
print("=====INDEX===== ", indexPath.row - 1)
print("number of statuses: ", statuses.count)
if(indexPath.row == 0){
print("creating newStatus")
let cell = dequeueReusableCell(withReuseIdentifier: "NewStatusCell", for: indexPath) as! NewStatusViewCell
// cell.event = self.event
return cell
}
NewStatusViewCell
This should always be called as the very first cell, and let's users post new statuses
class NewStatusViewCell: UICollectionViewCell, UITextViewDelegate {
let status = UITextView()
var event: Event? = nil
let placeholder = UILabel(frame: .zero)
let post = UIButton(type: .custom)
let tutorialView = UIView(frame: .zero)
override init(frame: CGRect) {
super.init(frame: frame)
backgroundColor = .white
status.frame = .zero
status.translatesAutoresizingMaskIntoConstraints = false
addSubview(status)
status.topAnchor.constraint(equalTo: topAnchor, constant: 10).isActive = true
status.leftAnchor.constraint(equalTo: leftAnchor, constant: 10).isActive = true
status.bottomAnchor.constraint(equalTo: bottomAnchor, constant: -50).isActive = true
status.rightAnchor.constraint(equalTo: rightAnchor, constant: -5).isActive = true
status.layer.borderWidth = 1.0
status.layer.borderColor = UIColor.lightGray.cgColor
status.isEditable = true
}
The original code included using this class as a delegate, but I have commented out all the relevant delegate code to try to get the textView to run with only apple's code, however before I did this I added a print() statement to the textViewShouldBeginEditing() function. This statement never appeared in my logs indicating it was never called
I know I've just layed out ALOT of code, but if anyone can see where I've gone wrong I would really appreciate any help you can offer.
As always please don't hesitate to ask for more information.
Thanks :)
EDIT
This is what the app looks like just now, the white box underneath "invitees" is the CollectionViewCell and the box inside that is the UITextView

Answer 1

Very common cause is adding subViews to the cell:
addSubview(status)
instead of to the cell's content view:
contentView.addSubview(status)
This applies to both UITableViewCell and UICollectionViewCell
Worth noting: for auto-layout, subViews should also be constrained to the contentView and not to the cell itself.
