iOS(iPhone and iPad) Application Development for Beginner

• First you need to learn objective C basics.
• Should know about the iOS Framework.
• Should know how the iOS controller works like UIViewController,UITableviewcontroller, UINavigationControler,UITabBarcontroller etc. 
• Do some homework with all the controls with xib and programatically then you will get a clear idea.
• If you want to become a master dont skip the basics.
• My advise is to start with stanford tutorial (pdf and video) for iOS5 (http://www.stanford.edu/class/cs193p/cgi-bin/drupal/downloads-2011-fall and http://itunes.apple.com/us/itunes-u/ipad-iphone-application-development/id473757255).
