The arguments to that UIColor method should be in the range of 0 to 1.
Divide each RGB value by 255 to get them into that range.

Hello, well I found the reason of the exception. But still they
color its not being changed.... if I put [UIColor blueColor] then
it works, but it doesn't work with RGB doing [[UIColor alloc]
initWithRed ...... ]
I tried also [UIColor colorWithCGColor:CGColorCreateGenericRBG
(....)]; but the compiler just decided to send error that the
method CGColorCreateGenericRGB its unreachable, even I have the
CoreGraphics library in the project and im importing in in the
file... dunno what to do.. I need to be very accurate with the color
that im setting, I know the values in rgb but why is not working?

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
