如何在swift中修改plist

Question

我希望能够快速修改我的 plist 中的值，但我无法弄清楚。到目前为止，我可以读取数组中的值，仅此而已。

var playersDictionaryPath = NSBundle.mainBundle().pathForResource("PlayersInfo", ofType: "plist")

var playersDictionary = NSMutableDictionary(contentsOfFile: playersDictionaryPath!)

var playersNamesArray = playersDictionary?.objectForKey("playersNames")? as NSArray

[println(playersNamesArray)][1]

Answer 1

首先，您不能写入应用资源中的 plist 文件。因此，您需要将编辑后的 ​​plist 保存到另一个目录。喜欢你的NSDocumentDirectory。

As in this answer mentioned 你可以这样获取文档路径：

let documentsPath = NSSearchPathForDirectoriesInDomains(.DocumentDirectory, .UserDomainMask, true)[0] as NSString

但要回答您的问题，您可以像这样编辑NSMutableDictionary：

//add entries:
playersDictionary.setValue("yourValue", forKey: "yourKey")

//edit entries:
playersDictionary["yourKey"] = "newValue" //Now has value 'newValue'

//remove entries:
playersDictionary.removeObjectForKey("yourKey")

另一方面，如果您想编辑 NSArray，则应改用 NSMutableArray。

我找到了方法：

    var playersDictionaryPath = NSBundle.mainBundle().pathForResource("PlayersInfo", ofType: "plist")

    var playersDictionary = NSMutableDictionary(contentsOfFile: playersDictionaryPath!)

    var playersNamesArray = playersDictionary?.objectForKey("playersNames")? as NSMutableArray

    //this is a label I have called player1Name
    playersNamesArray[0] = "\(player1Name.text)"

    playersDictionary?.writeToFile(playersDictionaryPath!, atomically: true)

顺便说一句，感谢 NSMutableArray，我没想到。
