We also build the "RhoElements2" application example. The size of the .ipa is 3 Mb. We installed in the iPhone terminal and when the app is executed no rhoelements window is shown. Only shows the message "Rhoelements runtime v1.0". We think the app does not have Elements v2.
How can we buil a RhoElements 2 app for iPhone ?
This may be a simple issue with the splash screen. If you are building an iOS app and have downloaded and installed the latest version of RhoStudio you are building a v2 application.
We do not provide or ship a Motorola Webkit engine for iOS at this time. The Motorola Webkit is based on the same branch as Safari 5 so we felt it wasn't necessary at the time. So you should not and will not see an increase in application size as a result of that. Using RhoElements enables other key enterprise features for the iOS device though that you can now take advantage of while developing.
Please make sure you have added "non_motorola_device" and "native_browser" under capabilities to build application for ios devices.
