Swift Changing the size of tableview cells - swift

Question

just like the title says I'm searching for a way to change the size of each cell in my tableview. I have 2 questions:
1) How can I change the size of all cells by the same amount in my tableview?
2) Is it possible to automatically adjust the size of the cell based on the length of the text in that particular cell?
I'm aware that there are already similar questions asked before but I couldn't manage to implement their answers correctly as they've been outdated for some time now. I'd appreciate any help, thank you in advance!

Answer 1

1) To change size of all cells with same type, first you need to create CellType, here is the explanation how to do this.

or you can check for indexPath.row, but it's not cool :)
Than here:
func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
switch cellType {
case firstType:
return firstCellTypeHeight
case secondType:
return secondCellTypeHeight
default:
return defaultCellHeight
}
}
2) Yes, its possible. You create your CustomCell. In your CustomCell you should
setup your textFields or labels inside ContentView. Your views with text will stretch your cell.
Important thing. In method above you must return special height like that.
return UITableViewAutomaticDimension
For example your code will looks like that.
func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
switch cellType {
case firstType:
return firstCellTypeHeight
case secondType:
return secondCellTypeHeight
// Your stretching cell
case textCellType:
return UITableViewAutomaticDimension
}
}
override func tableView(_ tableView: UITableView, estimatedHeightForRowAt indexPath: IndexPath) -> CGFloat {
switch cellType {
case firstType:
return firstCellTypeHeight
case secondType:
return secondCellTypeHeight
// Your stretching cell
case textCellType:
return UITableViewAutomaticDimension
}
}
