Subject [jira] [Commented] (CB-2851) iOS UIKit Crash webView:didCreateOrUpdateScrollingLayer:withContentsLayer
Date Mon, 08 Apr 2013 15:01:21 GMT

    [ https://issues.apache.org/jira/browse/CB-2851?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13625437#comment-13625437
] 

Pepe Cano commented on CB-2851:
-------------------------------

It is likely an apple bug, due to a Z-index rendered div.

I have modified the HTML content and the error seems to be disappeared.

> There are different crashes which appears sometimes on my application startup.
> - [__NSCFDictionary removeFromSuperlayer]
> - EXC_BAD_ACCESS
> The usual two root causes in my opinion are a memory management error (e.g. something
has died and you've kept an invalid pointer to it because reference counting failed) or a
not properly initialised thing of some kind that's being referenced before it's ready or erroneously,
maybe due to a programming error.
> Looking at the main thread there I think it's probably something running in something
like dispatch_async(dispatch_get_main_thread(),^{ ... and the thing being run is accessing
a pointer that's not valid or (in some cases) points to an old, dead thing.
