Question

我有一个功能，我必须通过当前月份＆amp;在Swift 3中获取API的年份参数。如果我在参数中传递hardCode，我得到儿子的响应，但我无法用当前月份和年。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。

Answer 1

您没有currentMonth和currentYear的值，所以您必须制作一些。

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))"
    }
}

现在你应该可以做任何你需要做的JSON。我应该注意currentMonth和currentYear现在属于Int类型，如果您需要它们作为字符串，您只需转换为String(currentMonth)和String(currentYear)。 / p>

let today = Date()
let dateFormatter = DateFormatter()
dateFormatter.dateFormat = "yyyy"
let year = dateFormatter.string(from: today)
dateFormatter.dateFormat = "MM"
let month = dateFormatter.string(from: today)

e.g。年= 2017月= 10

per @maddy

var calendar = NSCalendar.current
let today = Date()
let desiredComponents = Set<Calendar.Component>([.month, .year])
calendar.timeZone = TimeZone(identifier: "UTC")!
let components = calendar.dateComponents(desiredComponents, from: today)
components.year
components.month

获取当前月份＆amp;年和传递到API iOS Swift？
