iOS Help with XCode Mapview Annotation

[Ruoz]

Hi,

Im new to XCode and still learning. Wondering if you guys can help me with my problem with mapview, annotation. The problem is really taking a toll on me.

What im trying to do is this. All my annotation is setup. I have 2 locations listed. And when the user click on one of the location, a bubble would appear, saying the location title and subtitle. But when the user click on the ">" icon, within the bubble. 2 popups would appear. Showing 2 location information, instead of the one that is selected.

I have copy and paste the codes onto this board. If you have time, please take a look, Thanks!

Any help or guesses would be great help. Thanks alot!

I'm sure you found the cause already, above; if so, please mark the thread as resolved.
