UILabelでいくつかの異なるテキストを強調表示

Question

こんにちはこのフォームにuilabelテキストを表示する方法を知りたいですか？下図に示すように、すべてをハイライト表示されませdoest updatedStr =「ファッションガジェットの旅」が、ハイライトのテキストをデバッグの実際の中に

let str = value as? String 
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 = 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 
} 

。私が望む結果は、上記のイメージです。

@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; 
    }
