大佬教程收集整理的这篇文章主要介绍了Swift中非文字值的枚举，大佬教程大佬觉得挺不错的，现在分享给大家，也给大家做个参考。
enum FileType {
case VIDEO = ["name": "Video","contentTypeMatcher": "video/"]
case IMAGE = ["name": "Image","contentTypeMatcher": "image/"]
case AUdio = ["name": "Audio","contentTypeMatcher": "aduio/"]
case PDF = ["name": "PDF","contentTypeMatcher":"application/pdf"]
case TEXT = ["name": "Text","contentTypeMatcher": "text/"]
case FOLDER= ["name": "Folder","contentTypeMatcher" :"application/x-directory"]
case PLAIN = ["name": "Plain","contentTypeMatcher": ""]
}
当我使用元组时,它是一样的：
enum FileType {
case VIDEO = (name: "Video",contentTypeMatcher: "video/")
case IMAGE = (name: "Image",contentTypeMatcher: "image/")
case AUdio = (name: "Audio",contentTypeMatcher: "aduio/")
case PDF = (name: "PDF",contentTypeMatcher:"application/pdf")
case TEXT = (name: "Text",contentTypeMatcher: "text/")
case FOLDER = (name: "Folder",contentTypeMatcher :"application/x-directory")
case PLAIN = (name: "Plain",contentTypeMatcher: "")
}
除了文字之外别无其他可以用作原始值.
一种可能的解决方法是将字典表示为字符串 – 例如,您可以使用逗号分隔元素,使用冒号来键入值：
enum FileType : String {
case VIDEO = "name:Video,contentTypeMatcher:video/"
case IMAGE = "name:Image,contentTypeMatcher:image/"
...
}
var dictValue: [String : String] {
var dict = [String : String]()
var elements = self.rawValue.componentsSeparatedByString(",")
for element in elements {
var parts = element.componentsSeparatedByString(":")
if parts.count == 2 {
dict[parts[0]] = parts[1]
}
}
return dict
}
