AttributedString可以分為NSAttributedString和NSMutableAttributedString兩種，在使用中通過把AttributedString賦值給控制元件的attributedText屬性來新增文字樣式。具有該屬性的控制元件有UILabel、UITextField和UITextView。

首先，初始化：

NSString *string = @"這是一個富文字字串";
NSMutableAttributedString *attributedString = [[NSMutableAttributedString alloc] initWithString:string
 
];

然後，根據API中屬性順序依次詳細說明：

No.1 字型

[attributedString addAttribute:NSFontAttributeName
                         value:[UIFont systemFontOfSize:30.0f]
                         range:NSMakeRange(4, 3)];

No.2 段落

NSMutableParagraphStyle *paragraphStyle = [[NSMutableParagraphStyle alloc] init];
//行間距
 

paragraphStyle.lineSpacing = 5.f;
//段落間距
paragraphStyle.paragraphSpacing = 5.f;
//段落縮排畫素
paragraphStyle.firstLineHeadIndent = 25.f;
//整體縮排畫素
paragraphStyle.headIndent = 10.f;
//對齊方式
paragraphStyle.alignment = NSTextAlignmentLeft;
//段落[其他屬性參照NSMutableParagraphStyle]
[attributedString addAttribute:NSParagraphStyleAttributeName
                         value:paragraphStyle
                         range:NSMakeRange(0
 
, attributedString.length)];

No.3 前景色

[attributedString addAttribute:NSForegroundColorAttributeName
                         value:[[UIColor redColor]
                         range:NSMakeRange(4, 3)];

No.4 背景色

[attributedString addAttribute:NSBackgroundColorAttributeName
                         value:[UIColor redColor]
                         range:NSMakeRange(4, 3)];

string = @"flash player";
attributedString = [[NSMutableAttributedString alloc] initWithString:string];
[attributedString addAttribute:NSLigatureAttributeName

                         range:NSMakeRange(0, 5)];
[attributedString addAttribute:NSFontAttributeName
                         value:[UIFont fontWithName:@"futura" size:30]
