i want use value variable alarmvalint in alarmviewcontroller. below small portion of
alarmviewcontroller.swift:
class alarmviewcontroller: uiviewcontroller { @iboutlet weak var alarmtextfield: uitextfield! @iboutlet weak var alarmlabel: uilabel! @ibaction func alarmok(sender: anyobject) { let alarmvalfloat:float = nsstring(string: alarmtextfield.text).floatvalue let alarmvalint:int = nsstring(string: alarmtextfield.text).integervalue var alarmvaldec:float = alarmvalfloat - float(alarmvalint) var alarmvalsec = alarmvaldec*100 //println("\(alarmvalsec),\(alarmvaldec*100)") if (alarmvalfloat <= 10) { alarmlabel.text = "h2s alarm level = \(alarmvalint)min:\(alarmvalsec)sec" } else { alarmlabel.text = "invalid time. enter <= 10" } self.alarmtextfield.resignfirstresponder() } and want "append" value of alarmvalint array graphpoints in graphview.swift. small portion (starting few lines) of file:
graphview.swift
import uikit @ibdesignable class graphview: uiview { //weekly sample data var graphpoints:[int] = [4, 2, 6, 4, 5, 10, 3] //var graphpoints:[int] = [0] //graphpoints.append(alarmviewcontroller.alarmok.alarmvalint) //not surprised did not work how can use variable value first file , append value array in second file?
ans: assuming might have same question @ point way solved is: in alarmviewcontroller.swift: graphview.graphpoints.append(8)//8 appended array graphpoints
note: graphview subview of view in alarmviewcontroller view
you've declared alarmvalint local variable inside alarmok method. declare instance variable (outside of method, @iboutlets declared). need instantiate instance of alarmviewcontroller class. assuming you've called alarm:
graphpoints += alarm.alarmvalint of course, if you're using alarmvalint constant (declared using let), there's no need instantiate instance of class. use so:
graphpoints += alarmviewcontroller.alarmvalint
