Question

这是我的代码

 let dateValue = formatterDate.dateFromString(request.date)
        print("da = \(request.date)")
        let dayValue = NSDate()
        let compnentsDate = myCalendar.components(.Year, fromDate: dateValue!)
        let componentsDay = myCalendar.components(.Year, fromDate: dayValue)
        if compnentsDate.year == componentsDay.year && compnentsDate.month == componentsDay.month && compnentsDate.day  == componentsDay.day {
            cell.dateLabel.text = "today"
        }else {
            if compnentsDate.year == componentsDay.year && compnentsDate.month == componentsDay.month && compnentsDate.day  == (componentsDay.day + 1 ){
            cell.dateLabel.text = "tomorrow"
            }else {
                cell.dateLabel.text = request.date
            }

        }

如你所见，我正在制作印刷品，而印刷品的价值是：

da = Jan, 25, 2016

但是，代码总是转到第一个if语句，并告诉我“今天”

为什么请？

我的代码有什么问题？

您需要在调用components:fromDate:函数时指定所需的所有组件。

您需要传递.Year，.Month和.Day，而不仅仅是.Year。像这样：

let compnentsDate = myCalendar.components([.Year , .Month , .Day], fromDate: dateValue!)
let componentsDay = myCalendar.components([.Year , .Month , .Day], fromDate: dayValue)

为什么日期总是在今天虽然我通过了不同的约会
