[TIMOB-17355] iOS: SystemButton cannot be changed after creation

Problem Description

The following code demonstrates that the systemButton property cannot be changed after creation. This is not documented and of course it would be even better if it *could* be changed.

Testing Environment:

Titanium SDK: 3.2.3.GA and 3.3.0.GA Titanium CLI: 3.3.0 OS X Version: 10.9.3 IOS Simulator: 7.1

TEST CODE:

app.js

var btn = Ti.UI.createButton({
systemButton : Ti.UI.iPhone.SystemButton.ADD
});
 
var win = Ti.UI.createWindow({
backgroundColor : 'white',
rightNavButton : btn,
title : 'Click the button'
});
 
var nw = Ti.UI.iOS.createNavigationWindow({
window : win
});
 
btn.addEventListener('click', function(e) {
//console.debug('clicked but not changed');
console.info('clicked but not changed');
btn.systemButton = Ti.UI.iPhone.SystemButton.ACTION;
});
 
nw.open();
 

STEPS TO REPRODUCE:

- Create a simple project. - Update this code in app.js - Run this with testing environment. - Click to the systemButton or ADD button.

TESTING RESULT:

There is no any change in the systemButton or ADD button.
