I have a cell with subviews.
I can't figure out why the UIView boom
isn't visible. Here is my code:
let separator: UIView = {
let view = UIView()
view.backgroundColor = .yellow
return view
}()
let boom: UIView = {
let b = UIView()
b.backgroundColor = .red
return b
}()
override func setupViews() {
super.setupViews()
addSubview(separator)
addSubview(setNumberView)
addSubview(boom)
backgroundColor = .orange
addConstraintsWithFormat("H:|-20-[v0]", views: boom)
addConstraintsWithFormat("V:|-20-[v0]", views: boom)
addConstraintsWithFormat("H:|[v0]|", views: separator)
addConstraintsWithFormat("V:[v0(10)]|", views: separator)
separator
shows up as it is supposed to. Is there a bug in my xcode or something? I have tried restarting xcode, putting the view into a frame, and changing the cell size.
You are not setting any width or height to your view.
To properly setup the position of a view, you have to specify the horizontal position, the vertical position, the width and height.
The separator
correctly specifies all of them, the view
is missing constraints for width
and height
.
A way to fix that could be for example:
addConstraintsWithFormat("H:|-20-[v0]-20-|", views: boom)
addConstraintsWithFormat("V:|-20-[v0(100)]", views: boom)
