Fortunately, the solution is pretty simple. When the supportEncoding boolean field on a UILabel is set to true, the text supports color encoding in the [RRGGBB] format.
This means that we can have write text such as the following (the [-] is used to revert to a previous color):
[FF0000]Red[-] [00FF00]Green[-] [0000FF]Blue[-]
The reason I needed to do this was because we want the leading zeros in the Score UILabel to have a different colour than the actual score. And for that, I wrote this neat little method to format my current score to a string with a predefined number of leading zeros and then color those leading zeros independent from the main colour of the label text.
private string FormatScore(int score, string leadingZerosRGBColor, int totalDigits)
{
var scoreString = score.ToString(CultureInfo.InvariantCulture);
var zeros = totalDigits - scoreString.Length;
if (score == 0)
{
scoreString = String.Empty;
zeros++;
}
return String.Format("[{0}]{1}[-]{2}", leadingZerosRGBColor, new string('0', zeros <= 0 ? 0 : zeros), scoreString);
}
And the end result pretty much looks like our designer intended:
