本文通过一个具体的实例演示了如何使用NSAttributedString来设置iOS应用中特定文本片段的样式，包括加粗、删除线及字体颜色。

    NSString *text = @"Lorem ipsum dolor sit amet";
    [self.testAttributedLabel setText:text afterInheritingLabelAttributesAndConfiguringWithBlock:^ NSMutableAttributedString *(NSMutableAttributedString *mutableAttributedString) {
        NSRange boldRange = [[mutableAttributedString string] rangeOfString:@"ipsum dolor" options:NSCaseInsensitiveSearch];
        NSRange strikeRange = [[mutableAttributedString string] rangeOfString:@"sit amet" options:NSCaseInsensitiveSearch];
        
        // Core Text APIs use C functions without a direct bridge to UIFont. See Apple's "Core Text Programming Guide" to learn how to configure string attributes.
        UIFont *boldSystemFont = [UIFont boldSystemFontOfSize:14];
        CTFontRef font = CTFontCreateWithName((__bridge CFStringRef)boldSystemFont.fontName, boldSystemFont.pointSize, NULL);
        if (font) {
            [mutableAttributedString addAttribute:(NSString *)kCTFontAttributeName value:(__bridge id)font range:boldRange];
            [mutableAttributedString addAttribute:kTTTStrikeOutAttributeName value:@YES range:strikeRange];
            CFRelease(font);
        }
        //TTTAttributedLabel颜色设置
        [mutableAttributedString addAttribute:(NSString*)kCTForegroundColorAttributeName value:(id)[[UIColor blueColor] CGColor] range:boldRange];
//        [mutableAttributedString addAttribute:(NSString*)kCTForegroundColorAttributeName value:[UIColor blueColor] range:boldRange];
        
        return mutableAttributedString;
    }];
