I got two cells in my UITableView
. One is a custom UITableViewCell
and the other is a cell with a UITextView
inside and called the type TextViewCell
.
Because they are static I the cells are loaded in viewDidLoad
method from a xib:
textCell = Bundle.main.loadNibNamed(String(describing: TextViewCell.self),
owner: self, options: nil)?.first! as! TextViewCell
ratingCell = Bundle.main.loadNibNamed(String(describing: RatingCell.self),
owner: self, options: nil)?.first! as! RatingCell
Now I try to change the height with the the heightForRowAt
delegate:
func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
if indexPath.section == 1 {
return textCell.textView.contentSize.height
}
return ratingCell.ratingView.frame.height
}
I disabled scrolling on the UITextView
but the cell is not resizing properly. In fact the cells gets smaller. The constraints of the TextViewCell
look like this:
Any suggestions?
I think you need to use self-sizing UITableViewCell
. Replace your current implementation of heightForRowAt
with the following:
func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
return UITableViewAutomaticDimension
}
Now height of cells in your UITableView
object will be calculated automatically based on constraints. Also, add some estimated value for row height:
func tableView(_ tableView: UITableView, estimatedHeightForRowAt indexPath: IndexPath) -> CGFloat {
return 100.0 // You can set any other value, it's up to you
}
Now you will see that the UITextView
view fills the whole UITableViewCell
cell.
You should get the height of UITextView in heightForRowAt and return this height as cell height. See example below
let lblDescLong = UITextView()
lblDescLong.textAlignment = .left
lblDescLong.text = “your text for text view”
lblDescLong.font = YourFont(size: 12)
let newSize = lblDescLong.sizeThatFits(CGSize(width: widthForTextView, height: CGFloat.greatestFiniteMagnitude))
return newSize.height
