On iOS devices (iPad, iPhone, iPod touch) apps can be launched if they subscribe to a defined URL scheme. This is also known as 'app switching'.
iViewer 4 app supports being launched via URL Scheme as follows:
Use this to launch iViewer to a specific page designated by pagename
:
iviewer4:///page/pagename
Use this to simply launch iViewer to the startup page:
iviewer4://
iViewer Lite app supports being launched via URL Scheme as follows:
Use this to launch iViewer Lite to a specific page designated by pagename
:
iviewerlite:///page/pagename
Use this to simply launch iViewer Lite to the startup page:
iviewerlite://
iViewer next (beta) app supports being launched via URL Scheme as follows:
Use this to launch iViewer to a specific page designated by pagename
:
iviewernext:///page/pagename

iviewernext://
CF iViewer (legacy) app supports being launched via URL Scheme as follows:
Use this to launch iViewer to a specific page designated by pagename

iviewer:///page/pagename
Use this to simply launch iViewer to the startup page:
iviewer://
From iViewer, you can force other apps to be launched on Button press by assigning the URL Property of the button to a specific URL Scheme for the app you want to launch. Note that not all apps can be launched. The developer of the app must enable the feature and assign a special URL Scheme for their app to allow it to be launched from other apps.
iViewer will then either close or go to the background (depending if you have multitasking enabled in iViewer settings or not) whilst the desired app is launched.
