Change TableViewCell height depending on label.text? - ios

Question

How can I change the cell height to make the UILabel fit? I am not using Auto-Layout in my project.
Also, the TableViewCell text is set in the cellForRowAtIndexPath.
Code:
var commentsArray: [String] = []
override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell:TableViewCell = tableView.dequeueReusableCellWithIdentifier("cell", forIndexPath: indexPath) as! TableViewCell;
if self.commentsArray.count > indexPath.row{
cell.commentsText.text = commentsArray[commentsArray.count - 1 - indexPath.row]
cell.commentsText.font = UIFont.systemFontOfSize(15.0)
}
return cell
}
Any ideas?

Answer 1

The above comment of using heightForRowAtIndexPath is acceptable when not using auto layout, (though I highly recommend getting used it).
Calculating the height of a label when it's populated with a certain string can be done using the methods described in this post: How to calculate UILabel height dynamically?

1) You can use a method to set constraints and you can modify the height of the cell in this way:
(Example with a label called book_title in a custom UITableViewCell)
fune setupComponents(){
self.addSubview(book_title)
book_title.topAnchor.constraintEqualToAnchor(self.topAnchor, constant: 5).active = true
book_title.leftAnchor.constraintEqualToAnchor(self.leftAnchor, constant: 10).active = true
book_title.rightAnchor.constraintEqualToAnchor(self.rightAnchor).active = true
book_title.widthAnchor.constraintEqualToAnchor(self.widthAnchor, constant: -20).active = true
book_title.heightAnchor.constraintEqualToConstant(90).active = true
book_title.numberOfLines = 0
book_title.lineBreakMode = NSLineBreakMode.ByWordWrapping
}
2) You have to call this method inside these:
required init(coder aDecoder: NSCoder) {
super.init(coder: aDecoder)!
setupComponents()
}
override init(style: UITableViewCellStyle, reuseIdentifier: String?) {
super.init(style: .Subtitle, reuseIdentifier: "CellId")
setupComponents()
}
