Hi Manuel,

We have not been contacted with such a problem before, so can you share which is your project that exhibits the issue? What you can try on your end is to change the AutoHideSplashScreen Cordova setting to false by altering the config.xml of your project (see Edit Configuration Files)

If it still does not show your app, please download the iPhone Configuration Utility and see if any errors appear on the IOS Console when you try to LiveSync.

Unfortunately those logs do not show anything of use. We've however found your app and identified the culprit, which is a bug in Icenium ION that slipped into the latest version. Currently there is no workaround that we can offer for ION, but should you build your app with a provision - it would work as expected.

Sorry for the temporary inconvenience.

Hello Manuel,

We've released Icenium v.1.7 yesterday where the problem in ION has been addressed. Please upgrade your Icenium IDE and Icenium ION version from App Store.

Thanks for the patience.

Hello Manuel,

I tried with your "Intr.... T... 2" app but cannot reproduce the issue. Is that your problematic project and if not, what is its name?

Hello Manuel,

If that project does not work on your end, and it has been created prior we fixed the bug in Ion, it might be a cache issue. Please uninstall Icenium ION from your device and install it from the AppStore again. If that does not help, consider Exporting Your Project and Recreating it in a blank template.

On a side note: have you tried this on another iOS device?

Hi Mark,

Could you please elaborate more on your issue? What type of project are you building? What dependencies you have to third party libraries?

Hi,

Thank you for your prompt reply.

I'm building a Cordova 3.0 project, jQuery Mobile and no dependencies on any 3rd Party libraries or plugins.

When my app launches on iOS I get the Splashscreen for 1 or 2 seconds then a white screen flashes up for another 1-2 seconds before my app finally launches. I believe this is a common Cordova issues with many workarounds none of which appear to work for me and Icenium.

I think a resolution to this would please many people.

Thanks
Mark

Hello Mark,

The default behavior of every Cordova application that uses the Splashscreen plugin is to Auto-hide it after certain amount of time. Icenium Ion is only a develpoment host for Cordova applications and it should behave like a default Cordova application.

However, If you want to override this behavior in your final provisioned application you can do this by:

1. Set AutoHideSplashScreen in your iOS config.xml to false. This will cause your Splashscreen to stay until you manually hide it.
2. Hide your Splashscreen by calling navigator.splashscreen.hide(); in your deviceready for example.

There is a bug in the Spashscreen plugin that Icenium is building with and this doesn't work at the moment and will be fixed soon, but you can workaround this by adding the latest stable version form the Splashscreen repository.

Please note that this won't work in Icenium Ion as its config.xml has AutoHideSplashScreen set to true.

Thanks very much IIian,

I had been using the navigator.splashscreen.hide(); you mentioned without success so your information relating to the Splashscreen plugin will probably help me.

Thanks again for the detailed response it's very much appreciated.

Hi Ned,

As several other users have hit this problem we decided to update the splashscreen plugin for the upcoming hotfix next week. For the time being you can manually update to the latest splashscreen plugin by following these instructions:
  1. Push your app to a git repository. Navigate to the .proj file inside the app folder, open it and delete org.apache.cordova.core.splashscreen from <CorePlugins>.
  2. Download the splashscreen core plugin from Cordova (https://github.com/apache/cordova-plugin-splashscreen). You can delete docs and test folders as they are not needed and you can also delete all platform specific stuff that Icenium does not support (i.e. everything except Android and iOS)
  3. Import this as Custom Plugin inside your Icenium app.

That's it. Once you build your app, the AutoHideSplashScreen would be working as expected.

Steve

Hello Nikunj,

In order to investigate your issue further we will need your project so we could reproduce it locally.
For that purpose I will ask you to open a private ticket where to attach your project if created in VS extension or just provide its name if you have used our in-browser or Windows IDE.

I look forward to your reply.

Zdravko
