Subclassing UIView

Posted by Daniel Vela on May 1, 2011

When subclassing an UIView and you need to create a method for initialization, then you must choose at least one of the following.

  • initWithFrame. This is the default initializator. Implement it when your class is created from code.
  • initWithCoder. Implement this method when your UIView subclass will be created by the Interface Builder.
  • layerClass. Implement this when the view will be draw by an alternative method like OpenGL ES.
