resize static table View Cell with device changes

Question

i'm using static cell in a tableview controller .i've used custom height for each static cells. and it's fine in iphone Xs. but in smaller iphone i need the height change into smaller . how to do that ?

Answer 1

You can either:

1. Override / Implement heightForRow of the tableView delegate method.
2. OR if you're using UITableView.automaticDimension , you can of course adjust the constraints of the subviews of your cell.

And there are lots of ways to determine the type of iPhone the user currently has. You can determine the bounds (or height) of the current device, or use this long enum (I got this from somewhere here on Stackoverflow).

Sample usage:

if UIDevice().type == .iPhone5 {

}
