Part 9 - UIView's Opaque Property

  • Whether the Opaque property is true or false it will not hide/show the UIView.
  • This property is simply a hint to the drawing system to improve performance when set to true. If it knows the UIView is opaque then it won't draw anything behind it.
  • If Alpha is less than one, this property should be set to false.
  • From Apple documentation: The opaque property has no effect in system-provided classes such as UIButton, UILabel, UITableViewCell, and so on.
