在标签中显示 NSObject init

Question

我有一个简单的 viewcontroller，它显示两个标签，一个带有引号，一个带有作者。引用和作者放在 NSObject 中（见代码），显示的 quote/author 是随机的。我的问题是如何在特定标签中显示引用和作者。

 class Quotes: NSObject {
        var person : String
        var quote  : String

        init(person : String, quote : String) {
            self.person = person
            self.quote = quote
        }
    }

    let quotes = [

        Quotes(person: "Person1", quote: "Quote1"),
        Quotes(person: "Person2", quote: "Quote2"),
        Quotes(person: "Person3", quote: "Quote3" ),  ]


    override func viewDidLoad() {
    super.viewDidLoad()

        let range: UInt32 = UInt32(quotes.count)
    let randomNumber = Int(arc4random_uniform(range))
    let QuoteString = quotes.person.objectAtIndex(randomNumber) //ERROR here, how do I specify the choosen author from the randomization?  
    let AuthorString = quotes.quote.objectAtIndex(randomNumber)//ERROR here, how do I specify the choosen quote from the randomization?  


    self.quoteLabel.text = QuoteString as? String
    self.personLabel.text = NameString as? String

}

我想这是一个非常简单的解决方案，非常感谢帮助（我是编程新手）

Answer 1

您的数组和属性访问略有混淆。首先，从数组中访问Quote对象，然后访问对象的属性

let randomNumber = Int(arc4random_uniform(self.quotes.count))
let quote = self.quotes[randomNumber]
let quoteString = quote.quote
let authorString = quote.author

self.quoteLabel.text = quoteString
self.personLabel.text = authorString

在标签中显示 NSObject init
