Description
If you use setdata on IOS the tableviewrow dont release. If I compile with 1.7.0 Release Candidate there is no problems. This only appears if I try to compile to 1.7.0 final or 1.7.1. Using Intruments its clear the behavior difference between 1.7 RC and 1.7.1 and 1.7.0
Test case bellow:
var win = Titanium.UI.createWindow( |
{
|
title: 'Tableview Test' |
});
|
var runNumber = 0; |
var tableview = Titanium.UI.createTableView({ |
backgroundColor: 'white', |
border: 1,
|
borderColor: '#E0E0E0', |
width: 315,
|
height: 450,
|
left: 35,
|
top: 75,
|
allowsSelection: true, |
separatorStyle: Ti.UI.iPhone.TableViewSeparatorStyle.SINGLE_LINE
|
});
|
|
win.add(tableview);
|
|
|
var buttomSetData = Titanium.UI.createButton({ |
title: 'Set data', |
bottom: 50,
|
right: 480,
|
border: 1,
|
height: 100,
|
width: 47
|
});
|
|
|
buttomSetData.addEventListener('click', function (e) { |
var tableviewData =[]; |
|
for(var i=0;i<200;i++) |
{
|
var row1 = Ti.UI.createTableViewRow(); |
var infoLabel = Titanium.UI.createView({ |
height: 12,
|
width: 12,
|
//backgroundImage :'images/delrow.png', |
backgroundColor: 'red', |
top: 8,
|
left: 20
|
});
|
|
var textLabel = Ti.UI.createLabel({ |
color: '#000', |
text: 'Run number ' + runNumber + ' Row number ' + i, |
font: {
|
fontSize: 15
|
},
|
top: 5,
|
left: 50,
|
height: 20,
|
width: 260
|
});
|
row1.add(textLabel);
|
row1.add(infoLabel);
|
tableviewData.push(row1);
|
|
}
|
tableview.setData(tableviewData);
|
|
|
runNumber++
|
});
|
win.add(buttomSetData);
|
win.open();

Checked Against 1.7.2 release and 1.8 master cannot reproduce.
Tested against 1.7.2 release and 1.8 master
I can reproduce this problem with both 1.7.2 final and 1.8.0.v20110915133349. Watching via instruments shows row proxies are not being released or reused; memory grows continuously as you "reset" the table.
function setRows(_start) {
|
var rows = [];
|
var end = _start + 100;
|
for(var i = _start; i < end; i++) {
|
var row = Ti.UI.createTableViewRow({
|
title:'Test '+i
|
});
|
rows.push(row);
|
}
|
return rows;
|
}
|
var table = Ti.UI.createTableView({
|
data: setRows([]) ,
|
bottom: 70
|
});
|
var button = Ti.UI.createButton({
|
title: "Reset Data",
|
height: 50,
|
width: 200,
|
bottom: 10
|
|
});
|
var click = 0;
|
button.addEventListener("click", function() {
|
click += 100;
|
table.setData(setRows(click));
|
// The following doesn't release memory/row proxies either
|
// table.data = setRows(click);
|
// nor does
|
// table.data = [];
|
// table.setData(setRows(click));
|
});
|
win1.add(table);
|
win1.add(button);
|

To be honest, I have no idea how you 'cannot reproduce'... Just open instruments and you will see it.
I will stay with 1.7.0 RC until this is fixed.
I have tested with both the customer's code and the code I supplied using 1.8.1 and I cannot reproduce the leak. The object count grows till it hits a threshold and then objects are garbage collected as expected.
I tried attaching a screen to the ticket, but it didn't seem to work. Here's a screen shot of Instruments showing my testing session using the customer's code. https://skitch.com/skypanther/g7quq/screen-shot-2012-01-31-at-3.34.47-pm You can see memory use grow, then objects are GC'd, and memory then drops.
Thanks for raising this ticket. Please remember to state the build date and hash of the Titanium SDK you have tested. You will find this information in the log on application launch. Please read the Jira Ticket Checklist for future tickets.
