iPod Touch iOS 5.1 Hardware, iPhone 4 iOS 5.0.1 Hardware. No luck reproducing with simulator
Description
Hello devs,
I have found an issue where a Cordova application will crash if the user taps the clock or battery portion of the status bar while the contents of an HTML element with -webkit-overflow-scrolling: touch are removed and rebuilt. I will attach a sample project (built with Cordova 1.6.1) which makes it easy to repro the issue. Here are the repro steps:
- Build and launch the attached project on a device
- Click the "Regenerate" link
- Immediately start rapidly clicking on the clock in the top status bar
- Repeat until crash
In my tests the crash consistently happens on the first or second try. Note that the JavaScript in the sample project is intentionally inefficient, in an attempt to simulate a much more complicated DOM being created and destroyed.
Enabling Zombies yields the following error:
2012-08-04 15:59:32.837 cordovacrash[24214:707] *** -[UIWebOverflowScrollView _viewDelegate]: message sent to deallocated instance 0x605ef80
Googling for that error revealed two threads on StackOverflow with similar issues, but this seems to be the first concrete method reproducing the issue. I created another test project which took the same javascript and placed it in a UIWebKitView without Cordova, and I could not get the application to crash. this leads me to believe that something in the Cordova framework is to blame. While my test is on an older Cordova version (1.6.1), the threads on StackOverflow mentioned builds as new as 1.9.0
