Question

我希望能够在swift中修改我的plist中的值，但是我很难搞清楚它。到目前为止，我可以读取数组中的值，但就是这样。

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，您无法写入应用资源中的plist文件。因此，您需要将编辑过的plist保存到另一个目录。与您的NSDocumentDirectory一样。

As in this answer mentioned您可以像这样获取文档路径：

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

但是要回答您的问题，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，如果您想修改NSArray，则应使用NSMutableArray代替。

我找到了怎么做：

    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)

顺便说一下，感谢NSMutableArray，我没有想到这一点。
