ios - swift 4 : How to set only one word per row in an UITextView and create an array with each row

Question

我创建了一个UITextView，我希望每行只有一个单词，这样每次我按空格破折号时它实际上都会返回文本。如何让空格按钮返回而不是实际间隔文本？另外，有没有办法记录每个单词以创建自定义数组？ 这是我现在的代码:

@IBAction weak var wordView : UITextView!
@IBLabel weak var label : UILabel!

var words : [String] = []

override func viewDidLoad() {
    super.viewDidLoad()
    let endEditingTapGesture = UITapGestureRecognizer(target: view, action: #selector(UIView.endEditing(_:)))
        endEditingTapGesture.cancelsTouchesInView = false
        view.addGestureRecognizer(endEditingTapGesture)
}

@IBAction func button(_ sender: Any) {
    getArray()
}

func getArray() {
    for _ in words {
        words.append(wordView.text)
    }
}

每次按下按钮时，该按钮都应该向数组添加单词...我不确定这是最好的解决方案...有什么帮助吗？

如果您正在使用委托(delegate)来获取输入，则可以使用委托(delegate)。

这是示例代码。

func textView(_ textView: UITextView, shouldChangeTextIn range: NSRange, replacementText text: String) -> Bool {
    let oldText = NSString(format: "%@", textView.text)
    var newText = oldText.replacingCharacters(in: range, with: text)
    newText = newText.replacingOccurrences(of: " ", with: "\n")
    newText = newText.replacingOccurrences(of: "-", with: "\n")

    textView.text = newText

    let myWordArr = textView.text.components(separatedBy: "\n")
    print(myWordArr)

    return false
}

不要忘记设置委托(delegate)。
