Subject [jira] [Closed] (CB-3008) PhoneGap App hangs on iOS on 2nd load after killed off
Date Wed, 10 Apr 2013 20:33:16 GMT

     [ https://issues.apache.org/jira/browse/CB-3008?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Stephen McKamey closed CB-3008.
-------------------------------

       Resolution: Not A Problem
    Fix Version/s:     (was: 2.7.0)
                   2.6.0

While really hard to debug from within Cordova, this turned out to be due to a change in `onhashchange`
which (I can only assume) was causing an infinite loop of URL hash changes.

Closing, but perhaps a feature request would be a better way to diagnose things like this.
I don't know of a way to debug JS on the physical device.

> Within XCode, I clean and build the app. It has been deleted from the device so not updating
but is a fresh build. When run on the device (while tethered) it works as expected. Usually
hitting "Stop" within XCode and starting it back up will not reproduce the behavior as the
app is still running in the iPad's app tray.
> Repro steps:
> If I kill off the app via the iOS app switching tray, then it will never load back up
without deleting it and pushing a new build. The app never gets along far enough to trigger
the `deviceready` event or any console messaging. I am not familiar enough with XCode to produce
much more output than the console, so if you have advice of what to try, I'm receptive. I
looked at XCode's Profile options but they weren't very informative.
> Here is the console output for same app build, same device under both scenarios:
