Question

我的捆绑包中有一个plist文件，我使用以下命令将其转换为字典：

let path = Bundle.main.path(forResource: "myFile", ofType: "plist")
let dicFromFile = NSDictionary(contentsOfFile:path!)
myDictionary = dicFromFile as! [String : String]

但我也希望该应用程序检查此文件的更新，所以我把它放在共享网站上，所以它有一些网址，如下所示：

https://www.dropbox.com/s/8ri13i2wggaz6/myFile.plist

那么，如何让NSDictionary从这个文件的URL中读取？

Answer 1

要从远程URL加载数据，请使用异步方式和类PropertyListSerialization来反序列化属性列表。

let url = URL(string:"https://www.dropbox.com/s/8ri13i2wggaz6/myFile.plist"
URLSession.shared.dataTask(with:url) { (data, response, error) in
   if let error = error { print(error); return }
   do {
      let dictionary = try PropertyListSerialization.propertyList(from: data!, format: nil) as! [String:Any]
      // do something with the dictionary
   } catch {
      print(error)
   }    
}.resume()

如果属性列表文件仅包含String值 - 如问题中所假设 - 转换为[String:String]

NSMutableDictionary *autos = [[NSMutableDictionary alloc] initWithContentsOfURL:
                                 [NSURL urlWithString:@"https://www.dropbox.com/s/8ri13i2wggaz6/myFile.plist"]];

迅速

let path = NSURL.init(string: "https://www.dropbox.com/s/8ri13i2wggaz6/myFile.plist")
        let dicFromFile = let dicFromFile = NSDictionary.init(contentsOf: path as! URL)
        myDictionary = dicFromFile as! [String : String]
