Description

Searching a tableView with a searchBar is very sluggish when you add images to the tableView rows. If you remove the images from the rows it searches smoothly as expected. This behavior is much more obvious on a device than on the simulator. Step 1: run the code below Step 2: pull down on the tableView to see the searchBar Step 3: enter some text into the searchBar Step 4: notice that entering text into the searchBar is very sluggish Step 5: remove the images from the rows Step 6: notice that searching is no longer sluggish

var win = Titanium.UI.createWindow();
win.open();

var data = [];

for (var i=0; i < 200; i++) {
  data[i] = Ti.UI.createTableViewRow({
	  	hasChild:true,
	  	title:'Row '+i,
	  	rightImage: 'KS_nav_ui.png',
	  	leftImage: 'KS_nav_views.png'  
  	});
};

var search = Titanium.UI.createSearchBar({
	barColor:'#385292',
	showCancel:false,
	hintText:'search'
});
search.addEventListener('return', function(e)
{
search.blur();
});
search.addEventListener('cancel', function(e)
{
search.blur();
});

// create table view
var tableview = Titanium.UI.createTableView({
	data:data,
	search:search,
	searchHidden:true
});

win.add(tableview);
