ios - 在具有字典作为“值”的字典中追加和更新

Question

我想在字典的同一个键中添加多个值。我有一个 Dic 类型

 var dic1 = [String:[String:AnyObject]](

 dic1.updateValue(["name": cellName,"phone": Phone], forKey: "XYZ")

通过它更新键“XYZ”的值，但我想在同一个键“XYZ”中添加更多值。谁能帮我解决这个问题？

一个简单而优雅的解决方案:-

var mutDictionary = [String: NSMutableDictionary]()

//Initialising your mutDictionary:-
mutDictionary = ["Fighters" : ["First" : ["NAME" : "The Tigress", "Phone" : "2131231231"]]]

//Adding a key-hashabale(or in this case String-NSMutableDictionary) pair.  
//`.updateValue` adds a new parent pair to your mutDictionary if your key value is not present if the key is present then it will update that key's value.
mutDictionary.updateValue(["First" : ["NAME" : "Uruguay", "Phone" : "903192301293"]], forKey: "The Bosses")
mutDictionary.updateValue(["FirstOfHisKind" : ["NAME" : "Panda", "Phone" : "123454362"]], forKey: "The Dragon Warrior")    

//Appending data to your mutDictionary:-
mutDictionary["Fighters"]?.setObject(["NAME" : "Guru Shifu", "Phone" : "121212121212"], forKey: "Second")

 print(mutDictionary)

你从这里得到的输出是这样的:-

   ["Fighters"          : { Second = {  NAME = Guru Shifu; 
                                        Phone = 121212121212;};
                            First = {  NAME = The Tigress;  
                                       Phone = 2131231231;};
                              },
    "The Bosses"        : {First = { NAME = Uruguay;
                                     Phone = 903192301293;};
                              },
    "The Dragon Warrior": {First = { NAME = Panda;
                                     Phone = 123454362;};
                            }]
