UISplitView question and issues

Question

I created a new project with a UISplitViewApplication. When you do this you will find a DetailViewController and RootViewController. In the DetailViewController there is a UIToolbar on top that resizes according to the orientation, whether it's potrait or landscape. I accidentally removed this UIToolBar and I dragged a new one from the FileManager window, however after connecting everything this new one doesn't resizes according to the orientation. Why is this?

Also one more issue I am facing is related to this orientation stuff. I added a UITextField and UITableView, etc in this DetailView, however when switching in between the orientation everything is just messed up. How can I prevent this? How do I make my view consistent no matter what orientation it has...
