title: Segue from a MapView
body: <p>I’m new to iphone development.  What I’m trying to do is have a view controller with a mapview and annotation callouts that when one of the callouts is selected it will segue into another detail view controller with information, etc pertaining to the particular callout that was touched.  In interface builder when I try to ctrl drag from the mapview to the detail view controller nothing happens..I can’t create a segue.  I can’t select any of the annotation callouts because they are all in written in my .h &amp; .m files.  What am I doing wrong?  I know I have to have an identifier for the segue in order to proceed, but I can’t create the segue.</p>
