转换的NSDictionary斯威夫特词典

Question

现在我知道，当迅速编译它只是使一个的NSDictionary，但NSDictionary中和斯威夫特的字典有不同的语法。有没有一种方法（通过循环或东西）到NSDictionary中转换为相同类型<key, value>的迅速词典吗？

要么

有没有办法将其转换为一个斯威夫特字典而不是NSDictionary的？

let jsonDict = NSJSONSerialization.JSONObjectWithData(jsonData, options: nil, error: &error) as NSDictionary

Answer 1

采用：

let jsonDic = NSJSONSerialization.JSONObjectWithData(jsonData, options: NSJSONReadingOptions.MutableContainers, error: &error) as Dictionary<String, AnyObject>;

Answer 2

我找到答案从http://www.swift-studies.com/blog/2014/6/6/loading-a-swift-dictionary-from-a-plist-file

var swiftDict : Dictionary<String,AnyObject!> = Dictionary<String,AnyObject!>()
for key : AnyObject in ocDictionary.allKeys {
    let stringKey = key as String 
    if let keyValue = ocDictionary.valueForKey(stringKey){
        swiftDict[stringKey] = keyValue
    }
}

Answer 3

NSDictionary和Dictionary是几乎可以互换。因此，有没有必要，而且是您可以：

let jsonDict = (NSJSONSerialization.JSONObjectWithData(jsonData, options: nil, error: &error) as NSDictionary) as Dictionary
