在UILabel中突出显示几个不同的文本

Question

您好我想知道如何以此形式显示uilabel文字？

@JoinColumn(name="PARENT_ID") 

在实际的debuging期间，更新了Mr.Str =＆＃34; Fashion Gadgets Travel＆＃34;但高亮文本不会突出显示所有内容，如下图所示。我想要的结果是上面的图像。

@IBOutlet weak var myInterestsLbl:UILabel?


    let str = "Fashion Gadgets Travel";

    let updatedStr = str.replacingOccurrences(of: ",", with: "     ");
    self.myInterestsLbl!.text = updatedStr;

    //Highlight Text
    let string = self.myInterestsLbl!.text;

    if string?.range(of:"Fashion") != nil {
        let fashion = "Fashion";
        let range = (string! as NSString).range(of: fashion);

        let attributedText = NSMutableAttributedString.init(string: string!);
        attributedText.addAttribute(NSBackgroundColorAttributeName, value: UIColor(red: 0.98, green: 0.84, blue: 0.04, alpha: 1.0) , range: range);
        self.myInterestsLbl!.attributedText = attributedText;
    }

    if string?.range(of:"Gadgets") != nil {
        let fashion = "Gadgets";
        let range = (string! as NSString).range(of: fashion);
        let attributedText = self.myInterestsLbl!.attributedText as? NSMutableAttributedString;  // You did mistake here. You were initialising it via String variable instead of changed attributed string.
        attributedText?.addAttribute(NSBackgroundColorAttributeName, value: UIColor(red: 0.98, green: 0.84, blue: 0.04, alpha: 1.0) , range: range);
        self.myInterestsLbl!.attributedText = attributedText;
    }
