在循环中快速返回多个数组项

Question

我需要帮助。我试图带回单独的两个数组项，以便我可以对每个项应用单独的格式，即标题和注释。因此，我无法带回一个数组。

let pageTitle: [String] = runs.map({ $0.title })
let pageContent: [String] = runs.map({ $0.notes! })

for text in pagesTitle {
    let vc = TextViewController(with: text, text2: nil)
    myControllers.append(vc)
}
            
for text2 in pagesContent {
    let vc = TextViewController(with: nil, text2: text2)
    myControllers.append(vc)
}

我也试过了：

for text in pageTitle, pageContent {
    let vc = TextViewController(with: text, text2)
    myControllers.append(vc)
}

和

for text in pageTitle {
    for text2 in pageContent {
        let vc = TextViewController(with: text, text2)
        myControllers.append(vc)
    }
}

我的 init 需要 text 和 text2：

init(with text: String, text2: String) {
    self.myText = text
    self.myText2 = text2
    myTextView.text = self.myText
    myTextView2.text = self.myText2
    super.init(nibName: nil, bundle: nil)
}

你可以试试

let myControllers = runs.map {  TextViewController(with:$0.title, text2:$0.notes!) }

或

let myControllers = zip(pageTitle,pageContent).map {  TextViewController(with:$0, text2:$1)  }
