UITableView Scroll Bug?!

I have a UITableViewController view with a table view showing some items and I'm able to scroll normally but when I added a UIView to the header of the table view and added a UISearchBar to this UIView (just added this in IB, no additional code, nothing else) the table view does not scroll anymore, it bounces as if it would scroll but it blocks the scrolling.

If I tap on the search bar and afterwards cancel the search, then when it goes back to the original table view it scrolls normally.

Has anyone faced this issue before? Any suggestions?
