尝试打印整个数组,但只有最后一个打印到textview

我从一个带有WebKit的网页上得到一系列句子,我想把它们全部打印成一个文本视图.我想我有一个循环打印整个数组,但它只打印最后一句.

这就是我所拥有的

extension ViewController: WKScriptMessageHandler {
    func userContentController(_ userContentController: WKUserContentController, didReceive message: WKScriptMessage) {
        // Receive message from Javascript, check & process message
        if message.name == "english", let englishLines = message.body as? [String] {
            // All of the sentences are printing in my console
            print(englishLines) 
            //Try Loop to print all of sentences on individual line
            for englishLine in englishLines {
                let eachEnglishLine = englishLine
                textView.text = eachEnglishLine
            }
        }

只有最后一句打印在textView中.

有一个更简单的方法.不要打扰循环.

用以下代替你的循环:

textView.text = englishLines.joined(separator: "\n")

您的代码不起作用,因为您没有附加每一行.您可以简单地将每个值分配给文本视图,以便仅显示分配的最后一行.
