Potential causes for EXC_BAD_ACCESS exception in PhoneGap app for iOS?

Question

We're using PG 2.0 to wrap up a mobile app built with jQuery 1.8.2. We're on Xcode 4.4 and iOS 5.1.1.

We often encounter the following exception: Thread 1: EXC_BAD_ACCESS (code=1, address=0x130) . The stack trace is below. Here is the output from Zombies: * -[UIWebOverflowScrollView _viewDelegate]: message sent to deallocated instance 0xf4e0330**

We have no clue what could cause this since we're coding entirely in HTML and JavaScript, relying on PG to interface with the hardware.

Any clues? Has this happened to other PG users?

Thanks!

Answer 1

We removed references to -webkit-overflow-scrolling in the CSS, and this bug went away. Argh, Apple!
