ios - 获取当前的月份和年份并传递给API iOS Swift？

我有一个函数，其中我必须将当前的月份和年份参数传递给Swift 3中的Fetch API。代码：-

func raffleNumberGenerate(){
    let prs = [
        "month":currentMonth,
        "year" : currentYear,
        "raffle_result": "1" as String
    ]
    Service.StartWithoutLoading(prs as [String : AnyObject]?, onCompletion: { result in
        let jsonResponseSingle = result as? NSDictionary
        print(" JSON Response :- \(String(describing: jsonResponseSingle))"
}

提前致谢。

最佳答案

您没有currentMonth和currentYear的值，因此必须进行一些设置。

func raffleNumberGenerate() {
    let date = Date() // gets current date
    let calendar = Calendar.current
    let currentYear = calendar.component(.year, from: date) // gets current year (i.e. 2017)
    let currentMonth = calendar.component(.month, from: date) // gets current month (i.e. 10)

    let prs = [
        "month":currentMonth,
        "year" : currentYear,
        "raffle_result": "1" as String
    ]

    Service.StartWithoutLoading(prs as [String : AnyObject]?, onCompletion: { result in
        let jsonResponseSingle = result as? NSDictionary
        print(" JSON Response :- \(String(describing: jsonResponseSingle))"
    }
}

现在，您应该可以使用JSON进行任何操作。我应该注意，currentMonth和currentYear现在是Int类型，如果您需要将它们用作字符串，则只需说出String(currentMonth)和String(currentYear)即可进行转换。
