ios - Difference between 2 NSDates, and divide the result with an Int - Swift -


i've been developing swift ios apps few months, , i'm new dates, find bit difficult. want difference in days between 2 nsdate (one of them today, , other 1 string), , after that, number of days between them, , divide int(datamoneyleft), in order money per day.

thanks help!

here's code:

var datepassed1 : string? var datamoneyleft : int?  func getdatedifference(){     let date = nsdate()     let calendar = nscalendar.currentcalendar()     let components = calendar.components([.day, .month], fromdate: date)      //let year =  components.year     //let month = components.month     //let day = components.day      //-----------************-----------//      let dateformatter = nsdateformatter()     dateformatter.dateformat = "yyyy-mm-dd"     let datestring = dateformatter.datefromstring(datepassed1!)      let calendar1: nscalendar = nscalendar.currentcalendar()      // replace hour (time) of both dates 00:00     let date1 = calendar1.startofdayfordate(datestring!)     let date2 = calendar1.startofdayfordate(date)      let flags = nscalendarunit.day     let components1 = calendar.components(flags, fromdate: date1, todate: date2, options: [])      let finaldifference = components1.day   }

first convert second string nsdate using dateformatter. find difference between 2 nsdates using timeintervalsincedate.you timeintervalsincedate nstimeinterval.then can solve problem using difference.
