I have included Tab Bar Controller in my application. I have declared Outlet in the App Delegates' .h and .m file. When I am right clicking on File's Owner, It doesn't show me Outlet. OR If I double click on the Tab Bar Controller I could not see the Outlet. How to connect it... I have Included the XIB file in an empty app. I am using Xcode 4. Any body can tell me how to get APPLICATION DELEGATE icon when clicking on xib file...??
