swift - 如何将不同 dic 的值分配给 UIlabel

Question

我想知道如何将不同词典的值分配给标签 View 。我的 API 字典是:

languages: [
    {
    iso639_1: "ps",
    iso639_2: "pus",
    name: "Pashto",
    nativeName: "پښتو"
    },
    {
    iso639_1: "uz",
    iso639_2: "uzb",
    name: "Uzbek",
    nativeName: "Oʻzbek"
    },
    {
    iso639_1: "tk",
    iso639_2: "tuk",
    name: "Turkmen",
    nativeName: "Türkmen"
    }]

我做了:

@IBOutlet weak var langues: UILabel!

func languages () {
    for eachcountry in (Countries?.languages)! {
        langues.lineBreakMode = .byCharWrapping
        langues.numberOfLines = 3
        langues.text = eachcountry.name

        print(eachcountry.name!)
    }

在控制台中打印:

Pashto
Uzbek
Turkmen

但在 UIlabel 中它只显示:

Turkmen

如何在我的标签 View 中获得所有三种语言？

Answer 1

您的循环正在解析所有词典，并且仅将文本分配给最后一个词典。

可能的解决方案:

langues.text = languages.flatMap({ $0.name }).joined(separator: " ")
