How can I assign the default theme of a specific mobile OS to the automatic theme system?
By default, when you render an application in the ejm environment, the appview is set with the default theme based on the OS. For example, by default iOS light theme for iOS and holo light theme for Android. In order to apply the user desired theme for the specific OS, you have to set the specific theme option with data-ej-theme attribute in the head tag. Refer to the following code example.
if (ej.isIOS7()) //This will set default theme for iOS7 device.
else if (ej.isAndroid()) //This will set default theme for Android device.
