Convert string to NSDate and get date, hour, Minute (swift2.3)

Main code:

Get time model, parameter format: 2016-12-12 18:11:12

Func getdatemodelwithstring (datestr:string)->datemodel? {

var model:datemodel?

Let formatter =nsdateformatter.init ()

Date gets GMT time, which differs from Beijing time by 8 hours and requires the following settings

Formatter.locale = Nslocale.currentlocale ()

Formatter.dateformat = "Yyyy-mm-dd HH:mm:ss"

Let date = formatter.datefromstring (DATESTR)

If date!=nil {

Needrealvaluemessage ("------tool.h----Datemodel")

Model = Datemodel.getmodelwithdate (date!)

}

Return model

}

Class Datemodel:nsobject {

var year:int = 0

var month:int = 0

var day:int = 0

var hour:int = 0

var minute:int = 0

var second:int = 0

Classfunc getmodelwithdate (newdate:nsdate), datemodel{

Let model = Datemodel ()

Let calendar = Nscalendar.init (Identifier:nscalendaridentifiergregorian)

Iflet year = calendar?.component (Nscalendarunit.year, fromdate:newdate) {

Model.year = Year

}

Iflet month = calendar?.component (Nscalendarunit.month, fromdate:newdate) {

Model.month = Month

}

Iflet day = calendar?.component (Nscalendarunit.day, fromdate:newdate) {

Model.day = Day

}

Iflet hour = calendar?.component (Nscalendarunit.hour, fromdate:newdate) {

}

Iflet minute = Calendar?.component (Nscalendarunit.minute, fromdate:newdate) {

}

Iflet second = calendar?.component (Nscalendarunit.second, fromdate:newdate) {

Model.second = Second

}

Return model

}
