Question

我在arduino ide中添加了这段代码（bluetooth.print（“4”）;），它会在手机中打印出来吗？但是数据是44444444444，那么如何获得像4这样的数据不能重复？

Answer 1

enum Key: String {
    case id = "id", amount = "amount", createdAt = "createdAt", status = "status"
}

class Payment {

    let id: Int
    let amount: Int
    let createdAt: Int
    let status: String

    func compare(toOther other: Payment, byKey key: Key, ascending: Bool) -> Bool {
        switch key {
        case .id:
            return ascending ? self.id < other.id : self.id > other.id
        case .amount:
            return ascending ? self.amount < other.amount : self.amount > other.amount
        case .createdAt:
            return ascending ? self.createdAt < other.createdAt : self.createdAt > other.createdAt
        case .status:
            return ascending ? self.status < other.status : self.status > other.status
        }
    }
}

那只打印4次。但这可能不是你想要的答案。您必须提供更多细节才能获得真正有用的东西。
