我有一个带有主题和子主题信息的大嵌套结构数据文件。
struct Topic{
struct Topic1{
let name = "Topic 1"
let description = "Topic 1 description here."
struct SubtopicUniqueName1 {
let title = "Subtopic title here."
let subtopicDescription = "Some lorem ipsum description...."
let subtopicContent = ["First Sentence", "Second Sentence", "Hello"]
}
struct SubtopicUniqueName2 {
let title = "Subtopic title here."
let subtopicDescription = "Some lorem ipsum description...."
let subtopicContent = ["First Sentence", "Second Sentence", "Hello"]
}
}
struct Topic2{
let name = "Topic 2"
let description = "Topic 2 description here."
struct SubtopicUniqueName3 {
let title = "Subtopic title here."
let subtopicDescription = "Some lorem ipsum description...."
let subtopicContent = ["First Sentence", "Second Sentence", "Hello"]
}
}
}
我想获取包含Topic1,Topic2等所有“名称”的数组,以此类推,因为最后我最多可以有14个主题。当我尝试let allTopics = [Topic.Topic1, Topic.Topic2]
我想通过做类似的事情来获取信息>
for i in allTopics{ print(i().name) }
最后,因为Subtopics结构被嵌套得更远,我是否可以在Topic中以类似的方式访问它们的内容?
我有一个带有主题和子主题信息的大嵌套结构数据文件。 struct Topic {struct Topic1 {let name =“ Topic 1” let description =“ Topic 1 description here”。 ...
allTopics的类型是[Any],它隐藏特定类的成员。
您正在混淆值和类型。在这里,您实际上只有两种类型:主题和子主题。因此,让我们制作它们:
