Yes, it can be achieved with NSAttributedString:

NSString *yourString = @"This is to be bold. This is normal string.";
NSMutableAttributedString *yourAttributedString = [[NSMutableAttributedString alloc] initWithString:yourString];
NSString *boldString = @"This is to be bold";
NSRange boldRange = [yourString rangeOfString:boldString];
[yourAttributedString addAttribute: NSFontAttributeName value:[UIFont boldSystemFontOfSize:12] range:boldRange];
[yourLabel setAttributedText: yourAttributedString];
