4. JSON LIBRARY FOR SWIFT THERE ARE SO MANY !!!!!!!!!!!!! I WANT TO INTRODUCE ONE OF THEM TO YOU. UNBOX https://github.com/JohnSundell/Unbox
5. UNBOX { "title": "͢΂͕ͯFʹͳΔ", "summary": "16ਐ਺දه", "comment": "੕4ͭͰ͢" } struct Book { var title: String var summary: String var comment: String }
6. UNBOX struct Book : Unboxable{ var title: String var summary: String var comment: String init(unboxer: Unboxer) { self.title = unboxer.unbox("title") self.summary = unboxer.unbox("summary") self.comment = unboxer.unbox("comment") } } let book: Book? = Unbox(data)
7. UNBOX struct Book : Unboxable{ var title: String var review: String var comment: String init(unboxer: Unboxer) { self.title = unboxer.unbox("title") self.review = unboxer.unbox("review") self.comment = unboxer.unbox("comment") } } do { let book: Book? = UnboxOrThrow(data) }catch{ // Error handling }
8. UNBOX [ "subject": { color = 1e8bc3; name = English; number = 200;}, "content": ڭ͍͑ͯͩ͘͞ʂ, "grade": { name = "Senior High"; number = 500;}, "created_at": 2016-03-01T14:59:47Z, "id": 12646, "answers_count": 0, "user": { "avatar_url" = "https://s3/ൿີ/hajisirazu/file/4883/01456642777925.jpg?AWSAccessKeyId=?"; id = 303695; name = "tarop"; }, "status": active, "images": ( { height = 891; id = 4883; status = active; "thumb_l_url" = "https://s3/ൿີ/hajisirazu/file/7777/thumb_l_01456642777925.jpg?AWSAccessKeyId=?; "thumb_s_url" = "https://s3/ൿີ/hajisirazu/file/7777/thumb_s_01456642777925.jpg?AWSAccessKeyId=?"; url = "https://s3/ൿີ/hajisirazu/file/4883/01456642777925.jpg?AWSAccessKeyId=?"; width = 557; }) ]
9. UNBOX struct Grade : Unboxable{ let number: Int let name: String init(unboxer: Unboxer) { self.number = unboxer.unbox("number") self.name = unboxer.unbox("name") } } struct Subject :Unboxable{ let number: Int let name: String let color :String init(unboxer: Unboxer) { self.number = unboxer.unbox("number") self.color = unboxer.unbox("color") self.name = unboxer.unbox("name") } }
10. UNBOX struct User: Unboxable { let ID: Int let name: String let avatarUrl :String init(unboxer: Unboxer) { self.ID = unboxer.unbox("id") self.name = unboxer.unbox("name") self.avatarUrl = unboxer.unbox("avatar_url") } } struct Image: Unboxable { let height: Int let width :Int let id :Int let status :String let thumbLUrl :NSURL let thumbSUrl :NSURL let url :NSURL init(unboxer: Unboxer) { self.height = unboxer.unbox("height") self.width = unboxer.unbox("width") self.id = unboxer.unbox("id") self.status = unboxer.unbox("status") self.thumbLUrl = unboxer.unbox("thumb_l_url") self.thumbSUrl = unboxer.unbox("thumb_s_url") self.url = unboxer.unbox("url") } }
11. UNBOX struct Question: Unboxable { let ID: Int let content: String let user: User let subject: Subject? let grade: Grade? let createdAt: String let answersCount: Int let status: String let images: [Image?] init(unboxer: Unboxer) { self.ID = unboxer.unbox("id") self.content = unboxer.unbox("content") self.user = unboxer.unbox("user") self.subject = unboxer.unbox("subject") self.grade = unboxer.unbox("grade") self.createdAt = unboxer.unbox("created_at") self.answersCount = unboxer.unbox("answers_count") self.status = unboxer.unbox("status") self.images = unboxer.unbox("images") } } let question: Question? = Unbox(jsonData)
12. UNBOX TRANSFORMATIONS Unbox supports transformations that let you treat any value or object as if it was a raw JSON type. struct UniqueIdentifier: UnboxableByTransform { typealias UnboxRawValueType = String let identifierString: String init?(identifierString: String) { if let UUID = NSUUID(UUIDString: identifierString) { self.identifierString = UUID.UUIDString } else { return nil } } init() { self.identifierString = NSUUID().UUIDString } static func transformUnboxedValue(unboxedValue: String) -> UniqueIdentifier? { return UniqueIdentifier(identifierString: unboxedValue) } static func unboxFallbackValue() -> UniqueIdentifier { return UniqueIdentifier() } }
13. UNBOX OK. I KNOW WHAT YOU ARE ABOUT TO SAY TO ME.
14. UNBOX class Author : RLMObject, Unboxable { var name: String = "" var age: Int = 0 required convenience init(unboxer: Unboxer) { self.init() self.name = unboxer.unbox("name") self.age = unboxer.unbox("age") } }
15. UNBOX IT’S SIMILAR TO OBJECTMAPPER !!!!!!!!
16. UNBOX ENUM SUPPORT enum Android: Int, UnboxableEnum { case IceCreamSandwich case JellyBean case KitKat case Lollipop case Marshmallow static func unboxFallbackValue() -> Android { return .IceCreamSandwich } }
17. UNBOX CONTEXTUAL OBJECTS SUPPORT let author: Author? = try UnboxOrThrow(authorJson) let book: Book? = try UnboxOrThrow(bookJSON, context: author) UNBOX HAS HAD SUPPORT FOR PASSING AN OPTIONAL CONTEXT OBJECT INTO THE UNBOXING PROCESS.
18. UNBOX struct Book : UnboxableWithContext{ var title: String var body: String var comment: String var author: Author? var description : String { return "this is description" } init(unboxer: Unboxer,context:Author) { self.title = unboxer.unbox("title") self.body = unboxer.unbox("body") self.comment = unboxer.unbox("comment") self.author = context } } let author:Author? = Unbox(authorJson) let book:Book? = Unbox(bookJson, context:author)
19. UNBOX USE WHAT YOU LIKE !
