tableView problem

[dmelgoza]

I have a tableview that is acting wrong. Please help.

I have a plist with a list of buildings on my campus, I have a tableview loading the plist and then dropping a pin on the location of that building in my mkmapview. Everything worked fine...until.

I decided to add sections and sectionIndexTitlesForTableView .

I added a numberOfRowsInSection to tell the tableView how many items would be in each section and I then made the first cell of each section to start off at a certain point in the list (from the plist).

Everything looks fine, until I click on the actual cells. If I click on the first cell of every section it will drop the pin that belongs to the fist location on my plist. The second item of each section drops the pin belonging to the second item in the plist, so on and so forth. Please help if you can!

PS: I started off with the worldcities sample and hacked the crap out of it, but I'm stuck here.
