Question

将值设为

Fruit:- Apple,Banana,Mango
Flowers:- Rose,Lotus,Jasmine
Vegetables:-Tomato,Potato,Chilli

我想将dictionary设为如下

在 Objective-C 中，我们可以将其作为：

  Nsdictionary dict;
  dict = @{@"Fruit" : @[@"Apple", @"Banana", @"Mango"],
            @"Flowers" : @[@"Rose", @"Lotus",@"Jasmine"],
            @"Vegetables" : @[@"Tomato", @"Potato",@"Chilli"],
          };

如何在swift中制作相同的dictionary？

Answer 1

你可以这样做：

var dict : Dictionary = ["Fruit" : ["Apple", "Banana", "Mango"],"Flowers" : ["Rose", "Lotus","Jasmine"],"Vegetables" : ["Tomato", "Potato","Chilli"]]

您可以将其全局声明为：

var dict : [String : Array<String>] = ["Fruit" : ["Apple", "Banana", "Mango"],"Flowers" : ["Rose", "Lotus","Jasmine"],"Vegetables" : ["Tomato", "Potato","Chilli"]]

您可以这样声明空Dictonary：

var dict : [String : Array<String>] = Dictionary()

声明字符串＆amp; swift中的String数组
