Hello.
Im trying to change the color of a UIView programatically but
something is wrong.
Im pressing a button which triggers an IBAction, which does the
following:
[[self view] setBackgroundColor:[UIColor colorWithRed:20.0 green:10.0
blue: 30.0 alpha:1.0]];
but when I press the button the program blows with an
NSInvalidArgumentException..
what am I doing wrong?
thanks
Gustavo Pizano
