Kerri Shotts updated CB-12231:
------------------------------
Labels: easyfix ios (was: )
> EXC_BAD_ACCESS in the screen-orientation plugin
> -----------------------------------------------
>
> Key: CB-12231
> URL: https://issues.apache.org/jira/browse/CB-12231
> Project: Apache Cordova
> Issue Type: Bug
> Components: Plugin Screen Orientation
> Environment: Screen Orientation Plugin 1.4.2
> iOS 10.1.1
> Reporter: Markus Ruh
> Labels: easyfix, ios
>
> The screen-orientation plugin sometimes (seldom) throws a EXC_BAD_ACCESS and
> crashes the app.
> XCode points to the following line in YoikScreenOrientation.m when crashing:
> vc.view.backgroundColor = [UIColor clearColor];
> The reason for the bug is probably that the view should not be changed while
> it is in a background thread, but the UIView is not thread safe (see
> Threading Considerations in
> https://developer.apple.com/reference/uikit/uiview?language=objc).
> The simplest way to fix this is probably to call the following two lines from
> the main thread (= move them into the
> dispatch_async(dispatch_get_main_queue() block):
>
> vc.view.backgroundColor = [UIColor clearColor];
> vc.view.opaque = YES;
> But as I have never seen the the background as described in the comments "as
> it is briefly visible prior to closing" on my iPhone 6 even if I comment out
> these lines, I don't know if there might be any negative side effects (but
> probably not, as the view is presented later anyways)...
