Description
I have a tab window (window A) with a tableview. When I click on a row in the tableview it opens a new window (window B). All I have on window B is an onclick to close the window on the leftNavButton.
Window A onclick code:
https://gist.github.com/6548c7fa9543d81f2b90">https://gist.github.com/6548c7fa9543d81f2b90
Window B return code:
https://gist.github.com/ecdacf378723f990a9fe">https://gist.github.com/ecdacf378723f990a9fe
The memory goes as follows:
App first opens: 10.36 MB
Click on Table View Row and open Window B: 10.65
Click on close of Window B: 10.63
Click on table view row and open window B again: 10.75
Click on close of Window B: 10.71
If we add more data to Window B the memory leak is amplified.
Titanium version: 1.2.2
Titanium SK 1.7.0
Iphone SDK 4.1 up to 4.3
xcode 4.0.1
Currently fixed in side branch, not Master.
I used the provided sample code plus a few additions to get it working and set up a test with Instruments. Instruments showed to app at 1MB shortly after launch and analytics load. On the first window open, it rose to 1.14MB. After about 5 minutes of repeated row clicking and window opening, the memory hovered at 1.14-1.15 and showed no sign of a steady increase. This was with 1.7.0RC1 and iPhone 4, iOS 4.3.3. Closing.
