Swift-将plist文件读取到数组吗? [英] Swift - read plist file to an array?

问题描述

我创建了一个从英语单词到西班牙语单词的迷你翻译.我想使用englishArray.plist而不是englishArray = ["the cat"]如何创建它?

我还使用了localizable.strings来检索"el gato"的值"the cat"，但我想从englishArray.plist中检索到它

我从这里开始，但是不确定我是否走对了

let path = NSBundle.mainBundle().pathForResource("englishArray", ofType: "plist") 
let plistEnglishArray = NSArray(contentsOfFile: path!)

这是我其余的代码:

var englishArray: [String] = ["rainbow", "boots", "heart", "leaf", "umbrella", "tired", "angry", "cry", "the cat" ]


override func viewDidLoad() {
    super.viewDidLoad()
    // Do any additional setup after loading the view, typically from a nib.

    self.translateTextField.delegate = self
    picker.delegate = self
    picker.dataSource = self
}

override func didReceiveMemoryWarning() {
    super.didReceiveMemoryWarning()
    // Dispose of any resources that can be recreated.
}

@IBAction func translateButtonTapped(sender: UIButton) {

    let emptyString = self.translateTextField.text

    if (emptyString!.isEmpty) {

        print("please enter a word")

    }

    for transIndex in englishArray.indices {
        if englishArray[transIndex] == emptyString!.lowercaseString {

            //englishArray

            //translateLabel.text = "\(spanishArray[transIndex])"
            translateLabel.text = NSLocalizedString(emptyString!.lowercaseString, comment:"")


            print(emptyString)
            return

        }
    }
}

解决方案

将root对象更改为Array，然后

var myEnglishArray: [String] = []
if let URL = NSBundle.mainBundle().URLForResource("englishArray", withExtension: "plist") {
      if let englishFromPlist = NSArray(contentsOfURL: URL) as? [String] {
        myEnglishArray = englishFromPlist
      }
    }

I have created a mini translation from English words to Spanish words. I would like to use the englishArray.plist instead of my englishArray = ["the cat"] How can I create this?

I have also used a localizable.strings to retrieve the value "the cat" for "el gato" but I would like to retrieve this from englishArray.plist

I started off with this but not sure if I'm on the right path

let path = NSBundle.mainBundle().pathForResource("englishArray", ofType: "plist") 
let plistEnglishArray = NSArray(contentsOfFile: path!)

Here is the rest of my code:

var englishArray: [String] = ["rainbow", "boots", "heart", "leaf", "umbrella", "tired", "angry", "cry", "the cat" ]


override func viewDidLoad() {
    super.viewDidLoad()
    // Do any additional setup after loading the view, typically from a nib.

    self.translateTextField.delegate = self
    picker.delegate = self
    picker.dataSource = self
}

override func didReceiveMemoryWarning() {
    super.didReceiveMemoryWarning()
    // Dispose of any resources that can be recreated.
}

@IBAction func translateButtonTapped(sender: UIButton) {

    let emptyString = self.translateTextField.text

    if (emptyString!.isEmpty) {

        print("please enter a word")

    }

    for transIndex in englishArray.indices {
        if englishArray[transIndex] == emptyString!.lowercaseString {

            //englishArray

            //translateLabel.text = "\(spanishArray[transIndex])"
            translateLabel.text = NSLocalizedString(emptyString!.lowercaseString, comment:"")


            print(emptyString)
            return

        }
    }
}

解决方案

Change your root object to Array, then

var myEnglishArray: [String] = []
if let URL = NSBundle.mainBundle().URLForResource("englishArray", withExtension: "plist") {
      if let englishFromPlist = NSArray(contentsOfURL: URL) as? [String] {
        myEnglishArray = englishFromPlist
      }
    }
