iOS 6.1

[Steve]

Is iOS version 6.1 supported? My app was working without issue using version 6.0, but now crashes almost immediately after updating to version 6.1.

Hello Steve,

There are several things you can do to help us help you.

Can you reproduce it with fresh new project or it is specific to the project you are working on?
On what iOS device you are experience this issue?

Please can you use this tool: http://support.apple.com/kb/dl1466 to get a log from the device and send it at support {at} icenium.com. When you select your phone in the tool interface there is a "console" tab where you can see the system log. If app crashes on start up usually there is something in the log to help us figure out what went wrong.

Another option is to give us a crash log. Here is somewhat outdated tutorial but still accurate: http://www.ondemandworld.com/how-to-find-crash-logs/

Never hesitate to ask us a question :)

I got this from the device log. It seems to be a cordova issue (I'm using version 2.2). I'm testing on an iPhone 5.

Feb 14 20:31:50 Steves-iPhone Cordova220[155] <Warning>: Failed to load webpage with error: The operation couldn’t be completed. (NSURLErrorDomain error -999.)

Feb 14 20:31:51 Steves-iPhone Cordova220[155] <Error>: libMobileGestalt copySystemVersionDictionaryValue: Could not lookup ReleaseType from system version dictionary

So the app is not actually crashing but my app is just a blank page. I'm going to try using a different version of cordova for now, or try to find a work around.

Yeah, this is a Cordova issue. If I use Cordova version 2.0 or 1.8.1, then I don't have the blank screen problem. But with those versions I can't save a file to disk (File API).

Hi Steve,

I've just tested this with iOS 6.1 iPad mini using the blank starting project and it worked fine.

If you build in "Debug" mode this message is ok: "Feb 14 20:31:50 Steves-iPhone Cordova220[155] <Warning>: Failed to load webpage with error: The operation couldn’t be completed. (NSURLErrorDomain error -999.)". 

We cancel the first load of index.html and reload it straight after that disabling any caching so that LiveSync works. It will not happen in "Release" mode.


"Feb 14 20:31:51 Steves-iPhone Cordova220[155] <Error>: libMobileGestalt copySystemVersionDictionaryValue: Could not lookup ReleaseType from system version dictionary" this though is more worrying. It seems that is connected with crashes in applications with WebViews (which is what Cordova apps are). On one stackoverflow post they guess it could be memory related. Loading too many images could crash your app with error containing libMobileGestalt.

If it is Cordova 2.2 related can you post link to logged issue in Cordova tacking system?
