使用对象的属性将字典快速转换为数组(Swift transform dictionary into array using properties of object)

使用对象的属性将字典快速转换为数组(Swift transform dictionary into array using properties of object)

我有一个包含数组的对象的字典。 例如，让我们坐下每个对象工厂有对象管理器factory.manager 。

字典：

["key1": factory1] ["key2": factory2] ["key3": factory3]

我需要通过将字典转换为数组来获取所有管理器：

[factory1.manager, factory2.manager, factory3.manager]

我怎样才能使用map来避免使用循环。

I have a dictionary with objects that contains array. For example let's sat each object Factory has object manager factory.manager.

Dictionary:

["key1": factory1] ["key2": factory2] ["key3": factory3]

I need to get all managers by transforming dictionary to an array:

[factory1.manager, factory2.manager, factory3.manager]

How can I do it using map for example by avoiding using for cycle.

最满意答案

这将创建这些值的数组：

Array(dictionary.values.map{$0.manager})

假设字典实例的类型为[String:Factory]

This will create an Array of those values:

Array(dictionary.values.map{$0.manager})

assuming the dictionary instance is of type [String:Factory]
