Question

我想在文字中过滤双引号并与单词分开。但是当我用双引号添加双引号时（比如这＆＃34;＆＃34;＆＃34;），它没有用。我尝试用这种方式添加（＆＃34; \＆＃34;＆＃34;）在双引号之间，但它也没有用。

我的代码如下。你可以在FindCommonWords函数中看到我想要的东西。

我该如何解决这个问题？

感谢。

import UIKit

class FeedDetailVC: UIViewController, UIWebViewDelegate {

@IBOutlet weak var txtMain: UITextView!
@IBOutlet weak var scrollView: UIScrollView!
@IBOutlet weak var lblHeader: UILabel!

var commonWordsArray = [String]()
var selectedHeader = String()


override func viewDidLoad() {
    super.viewDidLoad()

    lblHeader.text = selectedHeader
    self.txtMain.sizeToFit()

    DispatchQueue.main.async {

        self.contentHeight = self.lblHeader.frame.height + self.txtMain.frame.height
        self.scrollView.contentSize = CGSize(width: self.view.frame.width, height: self.contentHeight + 100)
        self.reloadInputViews()

    }

    findCommonWords()

}


func findCommonWords() {

    let textViewText = txtMain.text


    var commonWords = textViewText?.lowercased().components(separatedBy: [" ",".",",","=","(",")","-","/",":","\""]).filter({ !$0.isEmpty })

    let rejectedWords: [String] = ["the","on","in","a","an","of","off","up","and","to","are","is","am","—","se","iphone","was","it","at","\""]


    for index in rejectedWords {
    commonWords = commonWords?.filter{ $0 != index}

    }


    let wordCounts = NSCountedSet(array: commonWords!)


    let sortedWords = wordCounts.allObjects.sorted(by: {wordCounts.count(for: $0) > wordCounts.count(for: $1) }) [0..<5]

    yPoint = self.txtMain.frame.height + 15

    for word in sortedWords {

    //print("\(word) \(wordCounts.count(for: word)) times")

    let sortedWordsLabel = UILabel()
    sortedWordsLabel.frame = CGRect(x: 0, y: 0, width: 120, height: 25)
    sortedWordsLabel.center = CGPoint(x: 80, y: yPoint)
    sortedWordsLabel.text = word as? String
    sortedWordsLabel.font = UIFont(name: "HelveticaNeue-Bold", size: 15)
    sortedWordsLabel.textAlignment = .left

    self.scrollView.addSubview(sortedWordsLabel)
    yPoint += 25

    commonWordsArray.append(word as! String)

    }

}

}

“字符串文字可以包含以下特殊字符：

转义的特殊字符\0（空字符），\\（反斜杠），\t（水平标签），\n（换行符），{{1} }（回车），\r（双引号）和\"（单引号）“
