我试图找出但无法解决任何问题。所以,请教各位。
有没有机会编写一个作为泛型返回的函数?
我的结构如下
struct WWSInterest: Unboxable {
var confirmation: Bool
var data: [WWSKeyValue]?
var message: String?
init(unboxer: Unboxer) throws {
self.confirmation = try! unboxer.unbox(key: "confirmation")
self.data = try? unboxer.unbox(key: "data")
self.message = try? unboxer.unbox(key: "message")
}
// static func createFrom(data: Data) -> WWSInterest? {
// do {
// let r: WWSInterest = try unbox(data: data)
// return r
// } catch {
// return nil
// }
// }
}
我想帮助功能如下
func create<T>(from data: Data) -> T? {
do {
let r: T = try unbox(data: data)
return r
} catch {
return nil
}
}
那可能吗?
BTW:对不起我的英语不好
// 编辑
WWSKeyValue 结构如下,
struct WWSKeyValue: Unboxable {
var key: String
var value: String
init(unboxer: Unboxer) throws {
self.key = try! unboxer.unbox(key: "key")
self.value = try! unboxer.unbox(key: "value")
}
}
