== Connecting the App Delegate Outlet to the Tab Bar Controller ==

Earlier in this chapter we created an outlet for the root view controller in the App Delegate. In order to enable this we must connect it to the ''Tab Bar Controller'' instance we have created. From within the ''MainWindow.xib'' file hold down the Control key, click on the ''Tab Bar App Delegate'' icon and drag the resulting line to the ''Tab Bar Controller'' icon. From the resulting Outlets menu, select the ''tabController'' outlet.
