iOS Custom background color on a UIView...

[PaulieBoy]

I am trying to set the background color of a UIView to a custom color, without much success!

I can set it to a standard color like this...

[self setBackgroundColor:[UIColor lightGrayColor]];

But, when I try to set a custom color, it defaults to white!

The example below should be displayed as pale blue

[self setBackgroundColor:[[UIColor alloc] initWithRed:134 green:166 blue:228 alpha:1.0]];

I could add a blank image, with the custom color, and add that, but that is affecting some of my animations then...

Am I using the right method?

Any help would be really appreciated...

OK, the value you're entering should be from 0 -> 1, e.g. 255 would be 1, 128 would be 0.5 etc. You can also just use:

[I][self setBackgroundColor:[[/I][I]UIColor colorWithRed[/I]:1.0 green:1.0 blue:1.0 alpha:1.0]];

Rather that using an init method.

Ah, this one caught me out too...setting RGB values on a 0..1 scale instead of the 8 bit scale you would usually use.

Here's a quick way of doing what you want:

// R: 128 G: 90 B: 200
UIColor *myColor = [UIColor colorWithRed:(128.0 / 255.0) green:(90.0 / 255.0) blue:(200.0 / 255.0) alpha: 1];
