Description

The default value for Ti.UI.IOS.Stepper.value is null, when it should be 0 according to: https://developer.apple.com/library/ios/documentation/UIKit/Reference/UIStepper_Class/index.html#//apple_ref/occ/instp/UIStepper/value *Steps to Reproduce Issue*: 1. Create a new Alloy project 2. Use the below code to demonstrate the issue 3. Run the project and click on "OK" *Actual Results* The value is output as null *Expected Results* The value is output as 0 *Notes* This impacts trying to decrement the stepper on first click. Trying to increment the stepper sets it to the step value. *Code*: *index.xml*

<Alloy>
    <Window class="container">
        <Stepper id="stepper" onClick="doClick" 
             top="30" tintColor="green" steps ="3" />
        <Button onClick="btnClick">OK</Button>
    </Window>
</Alloy>

*index.js*

function doClick(e) {
    Ti.API.info($.stepper.value);
}

function btnClick(e) {
    Ti.API.info($.stepper.value);
}

$.index.open();

PR: https://github.com/appcelerator/titanium_mobile/pull/8186 Demo Code:

   var win = Ti.UI.createWindow({
       backgroundColor: '#fff'
   });
   
   var stepper = Ti.UI.iOS.createStepper({
       top: 20,
       tintColor:"green",
       steps:3,
       maximum:30,
       minimum:0
   });
   
   var button = Titanium.UI.createButton({
      title: 'Get Value',
      top: "50%",
      middle: 0,
      width: 100,
      height: 50
   });
   
   button.addEventListener("click",function(e){
      alert(stepper.value); // or (stepper.getValue())
   });
   
   win.add(button);
   win.add(stepper);
   win.open();
