'anyObject'不能转换为'Dictionary <key,value>]'

Question

嗨,我想通过使用NSUserDefaut获取对象类型字典:

var favoritePlace = NSUserDefaults.standardUserDefaults().objectForKey("savePlace")!  as [Dictionary]

但我得到错误'anyObject'不能转换为'Dictionary]'

我也尝试:

var favoritePlace = NSUserDefaults.standardUserDefaults().objectForKey("savePlace")!  as [Dictionary<String, String>()]

但它也不起作用.谁知道我怎么能这样做？谢谢 !

Answer 1

两次尝试都是语法错误.

要转换为字典:Dictionary<Type, Type>或[Type : Type]

所以通过做

var favoritePlace = NSUserDefaults.standardUserDefaults().objectForKey("savePlace")! as [[String: String]]

要么

var favoritePlace = NSUserDefaults.standardUserDefaults().objectForKey("savePlace")! as [Dictionary<String, String>]
