What you could do is use an NSAttributedString.

NSString *boldFontName = [[UIFont boldSystemFontOfSize:12] fontName];
NSString *yourString = ...;
NSRange boldedRange = NSMakeRange(22, 4);

NSMutableAttributedString *attrString = [[NSMutableAttributedString alloc] initWithString:yourString];

[attrString beginEditing];
[attrString addAttribute:kCTFontAttributeName 
                   value:boldFontName
                   range:boldedRange];

[attrString endEditing];
//draw attrString here...
