Answer 1

将您的UIView “containerView”添加为IBOutlet并设置您的containerView.layer.borderWidth = yourDesiredWidth并设置containerView.layer.borderColor = yourNeededColor.cgColor

Answer 2

UIButton.layer.cornerRadius , UIButton.layer.borderColor , and UIButton.layer.borderWidth . layer is a property of UIView , so you can pretty much customize any view with it.

Answer 3

button.layer.borderColor = CGColor(srgbRed: 255/255, green: 126/255, blue: 121/255, alpha: 1)
