最基本的標籤使用只能讓同一字串有著同樣的屬性，那麼我想要有多重文字屬性 (Multiple Text Attribute)該怎麼做？比如字體有大有小，又如顏色有紅有黃，再如上標和下標等等，這一切都已經能實現了！

其實只要使用AttributedString就能同時塞入多種屬性，記得匯入<CoreText/CTStringAttributes.h>才能使用喔！

#import <CoreText/CTStringAttributes.h>

- (void)viewDidLoad
{
    [super viewDidLoad];
    UILabel *label = [[UILabel alloc]initWithFrame:CGRectMake(0, 100, 200, 80)];
    NSString *infoString = @"我是快樂測試人 歡迎來逍遙文工作室";

    NSMutableAttributedString *attString=[[NSMutableAttributedString alloc] initWithString:infoString];

    // 上標
    [attString addAttribute:(NSString *)kCTSuperscriptAttributeName value:@1 range:NSMakeRange(2, 2)];

    // 下標
    [attString addAttribute:(NSString *)kCTSuperscriptAttributeName value:@-1 range:NSMakeRange(8, 2)];

    // 字體
    UIFont *font = [UIFont fontWithName:@"Avenir-Light" size:24];
    [attString addAttribute:NSFontAttributeName value:font range:NSMakeRange(11, 6)];

    // 顏色
    UIColor *color = [UIColor whiteColor];
    [attString addAttribute:NSForegroundColorAttributeName value:color range:NSMakeRange(11, 3)];

    label.attributedText = attString;
    [label sizeToFit];

    [self.view addSubview:label];
}

編譯執行後的結果你在文章頂端就已經看過囉！

TextView 也是可以讓文字變得花俏～這次是想讓某些字可以變成連結可點擊，且文字下要有底線～
[str addAttribute:NSUnderlineStyleAttributeName value:@(NSUnderlineStyleSingle) range:NSMakeRange(8, 5)];
[str addAttribute:NSUnderlineStyleAttributeName value:@(NSUnderlineStyleSingle) range:NSMakeRange(16, 5)];
[str addAttribute:NSUnderlineColorAttributeName value:[UIColor blackColor] range:NSMakeRange(8, 5)];
[str addAttribute:NSUnderlineColorAttributeName value:[UIColor blackColor] range:NSMakeRange(16, 5)];
[str addAttribute:NSForegroundColorAttributeName value:[UIColor blackColor] range:NSMakeRange(8, 5)];
[str addAttribute:NSForegroundColorAttributeName value:[UIColor blackColor] range:NSMakeRange(16, 5)];</pre>
self.agreementTextView.attributedText = str;

// 連結想要可點擊卻不要可選取
#pragma mark - UITextViewDelegate
- (void)textViewDidChangeSelection:(UITextView *)textView
{
    if (textView == self.agreementTextView && textView.selectedTextRange != nil) {
        // `selectable` is required for tappable links but we do not want
        // regular text selection, so clear the selection immediately.
        textView.delegate = nil;//Disable delegate while we update the selectedTextRange otherwise this method will get called again, circularly, on some architectures (e.g. iPhone7 sim)
        textView.selectedTextRange = nil;//clear selection, will happen before copy/paste/etc GUI renders
        textView.delegate = self;//Re-enable delegate
    }
}
