(ios) NSMutableAttributedString 이용하여, 특정 텍스트 옵션 변경하기

NSMutableAttributedString는 특정 텍스트의 색상 및 폰트를 변경할 때 사용됩니다.


1. 초기화, 객체를 초기화 하고 변경한 text를 넣어줍니다.

NSMutableAttributedString *attributedString = [[NSMutableAttributedString alloc] initWithString:text];

----------------------------------------------------------------------------------------

2. addAttribute이용하여, 폰트를 변경할 수 있는 NSFontAttributeName 설정해주고, 

value 에 변경할 폰트를 적용해 줍니다. range는 변경을 원하는 범위를 적용해주면, 사용자가 원하는 텍스트에 폰트를 변경할수 있습니다

  // 폰트

[attributedString addAttribute:NSFontAttributeName

                             value: [UIFont fontWithName:FONT_NanumBarunGothic size:m_contentTextView.font.pointSize]

                             range:NSMakeRange(0, m_contentTextView.text.length)];

----------------------------------------------------------------------------------------

3. 폰트 이외에도 다양한 옵션들을 변경할수 있습니다.
