Subject [jira] [Commented] (CB-1184) Phonegap crashes on ios status bar tab when using page change transition effects

Neale Genereux commented on CB-1184:
------------------------------------

Hey guys,

Please note that the linked duplicate issue https://issues.apache.org/jira/browse/CB-1195
has a sample project which allows for 100% repro rate on this issue. In addition, the sample
project will only have this issue if used with the Cordova framework. If the same index.html
is used within a generic WebKit view, the issues will not occur. This leads me to believe
that the issue is at very least related to the Cordova framework, if not caused by it. Could
you please take another look at the issue with the sample project and if it is an Apple issue,
log a bug with Apple?

Thanks!

> This is not 100% reproducable, but seems to be a known problem: http://stackoverflow.com/questions/9700310/phonegap-xcode-ios-app-crashes-when-status-bar-is-tapped
since 1.4 Phonegap
> I wonder why it is not yet fixed.
> I use translate3d to make ios use hardware acceleration and make transitions smooth.
But that leads to status bar taps crashes app. When not using page transition effects, app
works just fine.
> Possible steps to reproduce.
> 1. Load 2 heavy divs with graphics, divs styled as -webkit-overflow-scrolling: touch;
> If divs are not heavy enough, bug is too unreproducable. 
> 2. Children of divs styled as -webkit-transform: translateZ(0) to prevent them from disappearing
during scroll
> 3. apply a transition to divs with hardware acceleration and transition. Like from "translateZ(0)
scale(0,0)" to "translateZ(0) scale(1,1)"
> 4. tab status bar. App crashes
