Question

我正在处理这个引用应用程序，我一直遇到两个错误，只是不想与我合作。它说“Type'businessQuote'没有成员（'array'/'dict'）”。在下面的屏幕截图中，您将看到该行上的错误。重点是让应用程序在提供的文本字段中显示随机引用。请你帮助我好吗？提前谢谢。

Code with the error

我的目标是让“ImportList”工作

'ImportList' Swift file

如果还有其他一些我忽略的问题，如果你可以把我链接到它，我将不胜感激。但我真的需要一个答案。再次感谢你。

以下是包含错误的代码：

import Foundation
import UIKit
import Social

class businessQuote: UIViewController {

//============================//
//********** Outlets *********//
//============================//

let utility = Utility()
@IBOutlet weak var quoteDisplay: UILabel!
@IBOutlet weak var authorDisplay: UILabel!
@IBOutlet weak var quoteBackground: UIImageView! //GET BACK TO THIS

//============================//
//********** General *********//
//============================//

let date = NSDate()
var Author: String = ""
var Quote: String = ""

override func viewDidLoad() {
    super.viewDidLoad()

    // Checks if time is greater then 3pm to change background
    let currentTime = utility.currentTime()
    if (currentTime >= 15 ) {
        quoteBackground.image = UIImage(named: "quote_background.png")
    } else {
        quoteBackground.image = UIImage(named:"morning_quote_background.png")
    }
}

//============================//
//********* New Quote ********//
//============================//

   override func touchesBegan(touches: Set<UITouch>, withEvent event: UIEvent?) {
    // Generates Random Number
    func randomNumber(arrayLength: Int) -> Int {
        let unsignedArrayCount = UInt32(arrayLength)
        let unsignedRandomNumber = arc4random_uniform(unsignedArrayCount)
        let randomNumber = Int(unsignedRandomNumber)


        return randomNumber
    }

    // Importing Quotes plist File
    let businessQuotes = ImportList(FileName: "BusinessList")

    // Selects Quote
    let chosenQuote: String = businessQuote.array[randomNumber(businessQuote
        .count())] as! String
    let chosenAuthor = businessQuote.dict[chosenQuote]! as String

    // Assigns Quote & Author to IBOutlet
    Author = chosenAuthor
    Quote = chosenQuote

    quoteDisplay.text = Quote
    authorDisplay.text = Author.uppercaseString

}

这是带有'array'和'dict'的代码

import Foundation

struct ImportList {
let path: String

init(FileName: String) {
    self.path = NSBundle.mainBundle().pathForResource("\(FileName)", ofType: "plist")!
}

var dict: Dictionary<String, String> {
    return NSDictionary(contentsOfFile: path)! as! Dictionary
}

var array: Array<AnyObject> {
    return [String](arrayLiteral: String(dict.keys) { $0 as AnyObject as! String })
}

func count() -> Int {
    return array.count
}
}

谢谢！

您已将变量 businessQuotes 声明为：

// Importing Quotes plist File
let businessQuotes = ImportList(FileName: "BusinessList")

但是，使用 businessQuote 代替您，看到您缺少＆＃34; s＆＃34;在末尾。拼写错误。以下行应该是：

// Selects Quote
let chosenQuote: String = businessQuotes.array[randomNumber(businessQuotes
    .count())] as! String
let chosenAuthor = businessQuotes.dict[chosenQuote]! as String

类型'___'没有成员'array'
