I have a map view with several annotations. Each annotation has a button that takes the user to a detail view for that annotation. The detail view currently has two labels, one for the title from the annotation and the other for the subtitle of the annotation, and a "Get Directions" button. I want the title label to be populated with the title from the annotation and the subtitle label to be populated with the subtitle from the annotation. I want the Get Directions button to take the user into the Maps app and give them directions to the address from their current location. I'd also like to add website and phone number to the detail view but I'm not sure how to populate those fields either. The detail view is called AnnotationDetailView but I haven't done anything with it besides add the button and labels in IB. I'm just not sure how to populate the labels and get the button doing what I want. Any help would be great.
Here is my code:
//
// RSFM.m
#import "RSFM.h"
#import "AnnotationDetailView.h"
@interface RSFM ()
@end
@implementation RSFM

and the AnnotationDetailView
//

@interface AnnotationDetailView ()
@end
@implementation AnnotationDetailView
@synthesize ti;
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil

I'm having a couple of issues with this. One, the label is not showing up. Two, I have an NSLog statement in my showDetails method to show me what marketAnnotations is. It is showing the title of the last annotation added.
