calloutAccessoryControlTapped use

[designomatt]

I am working in MapKit and trying to build out detail views of annotations through the "calloutAccessoryControlTapped" control. I want to pull a local HTML file detailing the points on the map into an existing UIWebView that I use in another portion of the app from the plist that stores all of the annotation data.

I am able to create the annotations, add unique icons for the annotations and push a the UIWebView, but I cannot for the life of me figure out how to load these local detail webpages into the view.

Has anyone faced this and come up with a viable solution?

plist item (truncated for this post - but they repeat for all points on the map)

<?xml version="1.0" encoding="UTF-8"?>

MyAnnotation.h

#import <Foundation/Foundation.h>
#import <MapKit/MapKit.h>

@interface MyAnnotation : NSObject <MKAnnotation> {

     CLLocationCoordinate2D coordinate;
     NSString *title;
     NSString *subtitle;
     NSString *imageName;
     NSString *bulletName;
     NSString *detailURL;
}

@property (nonatomic, readonly) CLLocationCoordinate2D coordinate;
@property (nonatomic, copy) NSString *title;
@property (nonatomic, copy) NSString *subtitle;
@property (nonatomic, retain) NSString *imageName;
@property (nonatomic, retain) NSString *bulletName;
@property (nonatomic, retain) NSString *detailURL;

@end

MyAnnotation.m

#import "MyAnnotation.h"

@implementation MyAnnotation
@synthesize coordinate, title, subtitle, imageName, bulletName, detailURL;

- (id) initWithDictionary:(NSDictionary *) dict
{
     self = [super init];
     if (self != nil) {
          coordinate.latitude = [[dict objectForKey:@"latitude"] doubleValue];
          coordinate.longitude = [[dict objectForKey:@"longitude"] doubleValue];
          self.title = [dict objectForKey:@"name"];
          self.subtitle = [dict objectForKey:@"address"];
          self.imageName = [dict objectForKey:@"imageName"];
          self.bulletName = [dict objectForKey:@"bulletName"];
          self.detailURL = [dict objectForKey:@"detailURL"];
     }
     return self;
}

@end

calloutAccessoryControlTapped

- (void)mapView:(MKMapView *)mapView annotationView:(MKAnnotationView *)view calloutAccessoryControlTapped:(UIControl *)control {

     //this determines what kind of item was selected
     if ([control isKindOfClass:[UIButton class]]) {

          //pushes the blank WebVC controller for all annotations
          WebVC *webVC = [[WebVC alloc] initWithNibName:@"WebVC" bundle:nil];
          [self.navigationController pushViewController:webVC animated:YES];

                //titles the new view
          webVC.title = @"Detail View";
                //releases the view
          [webVC release];
     }
}

The above works as you load a map, select an annotation and click:

 annotationView.rightCalloutAccessoryView = [UIButton buttonWithType:UIButtonTypeDetailDisclosure];

The "Detail View" pushes in and loads a blank UIWebView. It is loading those unique local HTML files to showcase detailed descriptions I cannot figure out.

I would be grateful if anyone could help with some direction for solving this conundrum, or if you have worked through this how you successfully managed this process. TIA

Here is one of the things I had been searching for in order to "know" which annotation was selected.

 if([view.annotation.title isEqualToString:@"Annotation Title Here"])

Knowing that you can then push another view controller or, in this case below, call up an alert view:

- (void)mapView:(MKMapView *)mapView annotationView:(MKAnnotationView *)view calloutAccessoryControlTapped:(UIControl *)control{
     
     if([view.annotation.title isEqualToString:@"Annotation Title Here"]){ [[[[UIAlertView alloc] initWithTitle:view.annotation.title
     message:@"Enter message here" 
     delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil] autorelease] show];

}

This is exactly what I was looking for in trying to leverage the calloutAccessoryControlTapped. Perhaps this will help someone else.

Hi,
im' sorry, i had try this but for me don't work it.
I had change

 if([view.annotation.title isEqualToString:@"Annotation Title Here"])

.[/quote]

to

if ([view.annotation isEqual:[PV4007 class]]) {
		CalloutViewController *detPV = [[CalloutViewController alloc] initWithNibName:@"Callout" bundle:nil];
		[self.navigationController pushViewController:detPV animated:YES];
		
	}
}

because i have the annotations in more class.. and i need to associate 1 kind of nib and class for 1 kind of annotation.
i had add annotation in view did load like this.

- (void)viewDidLoad {

	[mappa addAnnotation:[[PV4007 alloc] init]];
	mappa.delegate = self;
}

Where i'm wrong??tnx
