The basic way to launch a published application is as follows:
Open Parallels Client on your iOS device.
Connect to Parallels RAS. Once the connection is established, you'll see a list of available applications.
Tap the application you need and it will open.
However, there are a few other ways to launch a published application:
When you connect to Parallels RAS for the first time, Parallels Client receives a list of applications published for your user account. Then you can launch these applications from Spotlight:
Start typing the application name in Spotlight. The application will pop-down.
Tap the application - Parallels Client will start automatically, connect to Parallels RAS and the application will open.
If your iOS device supports 3D Touch technology, press down the Parallels Client icon to display a widget that allows you to open a connection or one of the published applications that you opened recently.
You can open a recently used connection or published applications from the Parallels Client widget. It can be added to the Today view screen.
To add the Parallels Client widget, do the following:
Press the Home button and swipe from left to right until you reach the Today view screen.
Scroll to the bottom of the screen and tap Edit.
Select Client from the MORE WIDGETS section.
If you work with some application most of your time, you can ask your administrator to configure it to open automatically. Once ready, just launch Parallels Client and connect to Parallels RAS - the application will open by itself.
