EXC_BAD_ACCESS in UIWebView

Question

I just downloaded the crash reports for one of my iPhone apps from iTunes Connect. The most common crash has a trace like the following:

Exception Type:  EX         


        

Answer 1

The scenario goes something like this:

1. User enters screen with UIWebView. The UIViewController sets self as the delegate
2. Web page starts downloading
3. User exits screen
   3a. UIViewController gets deallocated
4. UIWebView finishes loading and sends "I finished" message to its delegate...

You need to stop the UIWebView from loading its page and sets its delegate to nil before you deallocate the delegate.
