[TIMOB-6200] iOS: Table View setData Now Animates Rows In

Problem

Calling setData on a table view after the window has opened now causes the rows to animate in to view. By "animate in to view", I mean that they initially start at 0 height, and then expand to their regular height over the course of approximately half a second.

Expected Behavior

The rows should appear without any animation, unless I were to somehow specify that I wanted an animation. The existing behavior, before some recent commit to 1.8.0.1, should be maintained.

How to Reproduce

Drop the following in an app.js, and run it in the simulator. A couple of points to note: - I was very explicit about the height, although this isn't necessary to see the new animation behavior. I wanted to demonstrate that the issue wasn't caused by automatic height calculations, but is behavior that we introduced only recently. - If you setData outside of the 'open' event, you won't see the animation.

var win = Ti.UI.createWindow({ backgroundColor: '#fff' });

var table = Ti.UI.createTableView({
    rowHeight: 30
});
win.add(table);

win.addEventListener('open', function (evt) {
    table.setData([
        { title: 'Row 1', height: 30 },
        { title: 'Row 2', height: 30 },
        { title: 'Row 3', height: 30 },
        { title: 'Row 4', height: 30 },
        { title: 'Row 5', height: 30 },
        { title: 'Row 6', height: 30 },
        { title: 'Row 7', height: 30 },
        { title: 'Row 8', height: 30 },
        { title: 'Row 9', height: 30 },
        { title: 'Row 10', height: 30 }
    ]);
});

win.open();
