I want to calculate the distance between x-value
of two squares positioned in a view.
I did not work because in the frame there is also the y-value
and do not know how to select only one.
how can I add the x-values
from the position of the squares?
var redSquare: UIView = UIView()
var blueSquare: UIView = UIView()
var difference : Double = 0.0
func calc() {
difference = redSquare.frame - blueSquare.frame
}
CGRectGetMinX(redSquare.frame)
. CGRects can actually have negative width and height so the top left of it may not always be its origin. – Whin
