What's the best way to create a placeholder for a UITextView and the placeholder will have different colors and fonts. An example of what I want is:
_textView = [[UITextView alloc] initWithFrame:CGRectMake(7.0, 35.0, 306.0, 90.0)];
_textView.text = @"This is a variable called foo.";
I want "foo" in the text to be bolder and darker in color.
How's this best done?
