You would do something like this…
NSMutableAttributedString *hogan = [[NSMutableAttributedString alloc] initWithString:@"Presenting the great... Hulk Hogan!"];
[hogan addAttribute:NSFontAttributeName
value:[UIFont systemFontOfSize:20.0]
range:NSMakeRange(24, 11)];
This will set the last two words in 20-point text; the rest of the string will use the default value (which I believe is 12 points). The thing that might be confusing about setting the text size is that you have to set the typeface and the size at the same time—each UIFont
object encapsulates both of those properties.
