Subject [jira] [Commented] (CB-7182) Running mobile-spec in an iOS 8 project but using UIWebView results in an exception
Date Mon, 21 Jul 2014 20:24:38 GMT

    [ https://issues.apache.org/jira/browse/CB-7182?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14069209#comment-14069209

Shazron Abdullah commented on CB-7182:
--------------------------------------

Found it. My bad implementation using NSInvocation.

https://github.com/apache/cordova-ios/blob/28b4475070cd61587c8e7ac8e7f0102d8101367f/CordovaLib/Classes/CDVCommandQueue.m#L127

The getReturnValue here just copies buffer data, and does not retain. The runtime thinks it
does a retain, so it tries to release it again, thus crash.

Fix:
Use a different way instead of NSInvocation to achieve this, see: https://github.com/apache/cordova-ios/blob/28b4475070cd61587c8e7ac8e7f0102d8101367f/CordovaLib/Classes/CDVWebViewOperationsDelegate.m#L67

> Can't really trace it properly yet since it throws it in the UIApplicationDelegate and
putting symbolic breakpoints and catching all exceptions didn't give any results, but the
clue is in JavaScriptCore, probably. Note this is when the preference UseWKWebView is false
(which is by default)
