I am reading the Book: Beginning iOS 5 development.
One of it example is to drag the UIView into the table header of UITableView
I have tried many times, no matter how I drag my UIView above the UITableView, the UIView will not fit the table header. It just looks like a big rectangle.


I have solve my problem.
The answer is a little bit tricky, I cannot see the effect as same as the book shown, may be the interface builder has change a little bit. I can only see a small blue line on top of the table.
The view cannot be dragged directly into the table header.
objects list at the left.
Be aware of the object hierarchy.
