Setting the frame of the section index for a UITableView

Short question, I've been googleing around but cannot come up with a solution. I have a working UITableView with an index on the right side. At the top of the table I have a search field of approx. 44 px in height, placed in the first table cell. Unfortunately the section index shows over the search field, which looks a bit odd. Also, one cannot press the (X) button to erase in开发者_如何学编程put because the index is shown over it. Is there a way to lower the index so that the first cell is visible, without index overlap?

Any help is greatly appreciated!

Kind regards,
