如何在 Swift 中将值附加到多级字典？

Question

我有 swift 字典

var data = ["GenInfo":Dictionary<String,String>(),"LangInfo":Array<String>(),"EduInfo":Array<Dictionary<String,String>>(),"JobInfo":Array<Dictionary<String,String>>(),"SkillInfo":Array<Dictionary<String,String>>()]

现在我想向这本字典添加值，我该怎么做。 假设我想添加这些

"FirstName": "Varun",
"Email": "varun@gmail.com",
"State": "Rajasthan",
"Address": "Plot No. 00, Bhagwan Nagar 31,",
"Zip": "21354",
"Phone": "123456789",
"LastName": "Sharma"

valueForKey "GenInfo"

Answer 1

您在哪里制作字典（即 NSDictionary），其在声明后不可变（与 NSMutableDictionary 不同）。

也就是说，你可以这样做：

var data : NSMutableDictionary = ["GenInfo":Dictionary<String,String>(),"LangInfo":Array<String>(),"EduInfo":Array<Dictionary<String,String>>(),"JobInfo":Array<Dictionary<String,String>>(),"SkillInfo":Array<Dictionary<String,String>>()]

data["GenInfo"] = ["FirstName": "Varun",
                 "Email": "varun@gmail.com",
                 "State": "Rajasthan",
                 "Address": "Plot No. 00, Bhagwan Nagar 31,",
                 "Zip": "21354",
                 "Phone": "123456789",
                 "LastName": "Sharma"
                ]

data["LangInfo"] = ["English", "French", "Italian"]

data["EduInfo"]   = [["Degree": "MCA", "School": "University of Kota", "Year": "2013"], ["Degree": "Another degree", "School": "University of London", "Year": "2015"]]

// And so on...

或者像这样：

var data = [String: AnyObject]()

data["GenInfo"]   = [String: String]()   // Dictionary<String,String>()
data["LangInfo"]  = [String]()           // Array<String>()
data["EduInfo"]   = [[String: String]]() // Array<Dictionary<String,String>>()
data["JobInfo"]   = [[String: String]]() // Array<Dictionary<String,String>>()
data["SkillInfo"] = [[String: String]]() // Array<Dictionary<String,String>>()

data["GenInfo"]   = ["FirstName": "Varun",
                     "Email": "varun@gmail.com",
                     "State": "Rajasthan",
                     "Address": "Plot No. 00, Bhagwan Nagar 31,",
                     "Zip": "21354",
                     "Phone": "123456789",
                     "LastName": "Sharma"
                    ]

data["LangInfo"]  = ["English", "French", "Italian"]

data["EduInfo"]   = [["Degree": "MCA", "School": "University of Kota", "Year": "2013"], ["Degree": "Another degree", "School": "University of London", "Year": "2015"]]

// And so on...

像这样

var data: NSMutableDictionary = ["GenInfo":Dictionary<String,String>(),"LangInfo":Array<String>(),"EduInfo":Array<Dictionary<String,String>>(),"JobInfo":Array<Dictionary<String,String>>(),"SkillInfo":Array<Dictionary<String,String>>()]


data["GenInfo"] = ["FirstName": "Varun",
    "Email": "varun@gmail.com",
    "State": "Rajasthan",
    "Address": "Plot No. 00, Bhagwan Nagar 31,",
    "Zip": "21354",
    "Phone": "123456789",
    "LastName": "Sharma"
