Unfortunately, there are more problems with UIActionSheet. If you raise a UIActionSheet from a modal controller and a memory warning has come through, the view behind the modal view will have been blown away. For some reason, when you dismiss the modal view you’ll be left with a white screen. The underlying view gets loaded, but its viewWillAppear method is never called, and it’s never drawn.

I had several actions that could cause the modal view’s delegate to dismiss it, but only one caused the white screen. The only difference was that this action presented a UIActionSheet for confirmation. I switched it to a UIAlertView, and it works fine: no white screen when it’s dismissed.

Just so you know… if you build your app so every digit is an individual UILabel, and you set the alignment to “right” or “left” in the attributes inspector, you get the desired ‘monospace’ effect. Really cool.

Thanx, saved me this time.

On the other hand, you can avoid CGColor at all:

+ (UIColor *)colorFromRGBIntegers:(CGFloat)red green:(CGFloat)green blue:(CGFloat)blue alpha:(CGFloat)alpha
{
CGFloat redF = red/255;
CGFloat greenF = green/255;
CGFloat blueF = blue/255;
CGFloat alphaF = alpha/1.0;

UIColor *result = [UIColor colorWithRed:redF green:greenF blue:blueF alpha:alphaF];

return result;
}
