Question

到目前为止，我在iOS中还是新手。我做了很多尝试以获得输出，但是没有得到。请帮忙，我想以Array语言将数据存储到Objective-C这样的格式：

(
    {
    Appearance = Copper;
    Bitterness = 50;
    Style = "India Pale Ale (IPA)";
},
    {
    Appearance = "Jet Black";
    Bitterness = 35;
    Style = Stout;
},
    {
    Appearance = Copper;
    Bitterness = 25;
    Style = "English Brown Ale";
},
    {
    Appearance = "Deep Gold";
    Bitterness = 25;
    Style = Bock;
}
)

任何人都可以帮助我。

这是在Array中创建Dictionary的方法：

目标C：

NSArray *arrTemp = @[
                     @{@"Appearance" : @"Copper",
                       @"Bitterness" : @(50),
                       @"Style" : @"India Pale Ale (IPA)"},

                     @{@"Appearance" : @"Jet Black",
                       @"Bitterness" : @(35),
                       @"Style" : @"Stout"},

                     @{@"Appearance" : @"Copper",
                       @"Bitterness" : @(25),
                       @"Style" : @"English Brown Ale"},

                     @{@"Appearance" : @"Deep Gold",
                       @"Bitterness" : @(25),
                       @"Style" : @"Bock"}
                     ];

迅速：

        let arrTemp: [[String:Any]] = [
                                    ["Appearance" : "Copper",
                                     "Bitterness" : 50,
                                     "Style" : "India Pale Ale (IPA)"],

                                    ["Appearance" : "Jet Black",
                                    "Bitterness" : 35,
                                    "Style" : "Stout"],

                                    ["Appearance" : "Copper",
                                    "Bitterness" : 25,
                                    "Style" : "English Brown Ale"],

                                    ["Appearance" : "Deep Gold",
                                    "Bitterness" : 25,
                                    "Style" : "Bock"]
                                  ]

Answer 2

字典是这样初始化的：

NSDictionary *dict = @{ key : value, key2 : value2};

像这样初始化数组：

NSArray *array = @[Object1, Object2]

因此，您可以根据数据创建Dictionary对象，并像这样添加到数组中

NSArray *array = @[DicObject1, DicObject2]
