问题描述

我有一个 NSDictionary 列表，我想将它保存在一个文件中.我可以将它保存在文本文件中，但我无法将其读取到 [NSDictionary]

I have a list of NSDictionary, and i want to save it in a file. I can save it in text file but i can't read it to [NSDictionary]

try json.write(to: path, atomically: false, encoding: String.Encoding.utf8)

这是我的清单 NSDictionary

This is my list NSDictionary

[{ change = true; name = data1; },{ change = true; name = data2; }]

推荐答案

您可以使用 plist 来获取数据字典.下面是我们如何将数据写入 plist 文件.

You can user plist for dictionary of data. Here is how we write data to plist file.

var paths = NSSearchPathForDirectoriesInDomains(.DocumentDirectory, .UserDomainMask, true)[0] as String
var path = paths.stringByAppendingPathComponent("data.plist")
var fileManager = NSFileManager.defaultManager()
if (!(fileManager.fileExistsAtPath(path)))
{
    var bundle : NSString = NSBundle.mainBundle().pathForResource("data", ofType: "plist")
    fileManager.copyItemAtPath(bundle, toPath: path, error:nil)
}
data.setObject(object, forKey: "object")
data.writeToFile(path, atomically: true)

从plist文件中读取数据，

To read data from plist file,

var paths = NSSearchPathForDirectoriesInDomains(.DocumentDirectory, .UserDomainMask, true)[0] as String
var path = paths.stringByAppendingPathComponent("data.plist")
let save = NSDictionary(contentsOfFile: path)
