range(of:in:for:)

Returns the range of absolute time values that a smaller calendar unit (such as a day) can take on in a larger calendar unit (such as a month) that includes a specified absolute time.

Declaration

func range(of smaller: NSCalendar.Unit, in larger: NSCalendar.Unit, for date: Date) -> NSRange

Parameters

  • smaller:

    The smaller calendar unit.

  • larger:

    The larger calendar unit.

  • date:

    The absolute time for which the calculation is performed.

Return Value

The range of absolute time values smaller can take on in larger at the time specified by date. Returns {NSNotFound, NSNotFound} if larger is not logically bigger than smaller in the calendar, or the given combination of units does not make sense (or is a computation which is undefined).

Discussion

You can use this method to calculate, for example, the range the Day unit can take on in the Month in which date lies.
