title: Search NSArray and return the id of the row
body: <p>I would like to search an array and return the row number i.e. 0-10. The reason is I am loading information from a database and need to auto select a value in a uipicker view and from my understanding you can only select things in a uipicker view by the row id. So I would like to search the array with a string and return the row id so that I can tell the uipicker view what row to select. </p>
