UIButton doesn't have a "frame" property, so why is valid this "self.showQuote.frame = CGRect(100,250,280,44)

Hi Andres, if you go to xcode then if you select a button then go to the utilities pane and then click on the size inspector, you will find a frame layout, which i guess does represents the frame property of a button. Frame property just shows where a button will be placed (ie the x and y coordinates) in the view and what will be the size( ie the width and height) of the button.

So, self.showQuote.frame=CGRectMake(100,250,280,44); is a valid statement and does work.

Thanks. Now I understand UIButton inherits from UIView, which has a frame attribute. BTW I have to uncheck Autolayout in order to see the modifications of the button with CGRect
