I'm trying to get the real height of my custom UIButton. But I always get a value that is way smaller than I expected. I get something around 30 but expected something about 45.

override func awakeFromNib() {
  print(self.frame.height)
  self.layer.cornerRadius = self.layout.frame.height / 2.0
  self.clipsToBounds = true
  self.titleLabel?.adjustsFontSizeToFitWidth = true
}

This is my code, but at runtime somehow autolayout changes the size, which is perfect, but I can not set the right cornerRadius (always too small). So maybe I need the multiplier or something like that. I already testet with adding the contentEdgeInsets of top and bottom, but it made no difference.

Thanks Tobias

The view hasn't been laid out in awakeFromNib(). Set your corner radius when layout has guaranteed to have happened.

For a view:

override func layoutSubviews() {
  super.layoutSubviews()
  layer.cornerRadius = frame.height / 2.0
}

For a UIViewController:

override func viewDidLayoutSubviews() {
  super.viewDidLayoutSubviews()
  view.layer.cornerRadius = view.frame.height / 2.0
}

Try calling self.layoutIfNeeded() before you print the size
