ios - Swift 3 - 如何访问属性列表

Question

这是我创建的属性列表:

我只想将国家/地区名称加载到数组中。这是我到目前为止的代码...

if let path = Bundle.main.path(forResource: "flagData", ofType: "plist") {
    dict = NSMutableDictionary(contentsOfFile: path)

    let currentGroup = (dict!["caribbean"] as AnyObject).allKeys as? [String]
}

但这不起作用 - 当我运行它时，currentGroup = nil

我也试过:

let currentGroup = dict?.allKeys(for: "caribbean")  

但这给了我一个空数组。

任何想法将不胜感激......谢谢!

Answer 1

        if let path = Bundle.main.path(forResource: "flagData", ofType: "plist"),
            let configurations = NSDictionary(contentsOfFile: path) {
                variables = configurations[currentConfiguration] as! NSDictionary
        }

尝试上面的代码并进行相关更改，我认为您的代码中的错误是在您执行失败时出现的。
