Shazron Abdullah commented on CB-347:
-------------------------------------
Looking at the code, the fix is applied here:
https://github.com/apache/incubator-cordova-ios/blob/master/CordovaLib/Classes/CDVViewController.m#L167
But the page is loaded here:
https://github.com/apache/incubator-cordova-ios/blob/master/CordovaLib/Classes/CDVViewController.m#L197
There shouldn't be security errors before the page is loaded since there would
be no calls to localStorage/WebSQL.
So the sequence of events appears to be correct, and they should occur
synchronously. The only thing is, the UIWebView is created first before either
of the code blocks, and perhaps during the UIWebView initialization, it picks
up the .plist values.
In my testing, and probably in other users' testing when they tested the patch,
this UIWebView initialization of .plist values happens *after* the patch is
applied (a fluke of timing), so everything appears ok - while in your case, it
is the opposite.
The evidence points to the UIWebView picking up the .plist locations after it
is instantiated (which makes sense if one was to design the class), but before
a request is handled.
The fix for this would be to apply the patch before the UIWebView is
instantiated.
