Question

I would like to set the silver color for my UITextView border. I tried this:

theGroupTextLabel.layer.borderWidth = 3.5f;
    theGroupTextLabel.layer.borderColor = [[UIColor whiteColor] CGColor];

…but in the color option there are only some colors like whiteColor, BlackColor, Green…

What if I want silver?

Answer 1

You will just need to customize your color with RGB values because what you are seeing are just a handful of predefined colors for your convenience. This is an example of a custom color with RGB values.

[[UIColor colorWithRed:0.5f green:0.2f blue:0.7f alpha:1.0f] CGColor]; // Not actually silver

NOTE: Normally you will find a number between 0 and 255 for each value but this function takes floats so just take those number and divide it by 255 to get the float value of what you need.
