Question

Xcode错误:没有更多上下文,表达式类型不明确

我如何解决它？

let componentss = calendar.components(.CalendarUnitYear | .CalendarUnitMonth | .CalendarUnitDay | .CalendarUnitHour | .CalendarUnitMinute | .CalendarUnitSecond, fromDate: date)

Answer 1

CalendarUnit名称在Swift 2.0中已更改.试试这个:

let componentss = calendar.components([.Year, .Month, .Day, .Hour, .Minute, .Second], fromDate: date)
