Please do not post the same thing multiple times. The board software automatically flags certain posts as needing moderator attention. This happens the most often for new users. I'm pretty sure this is made clear at the time you attempt to post. Posting the same thing over and over again just makes that many more posts the moderators have to weed through later. This makes us sad. Don't make us sad. If your post/thread doesn't appear, just wait a while. Don't post it again. If it hasn't shown up by the next day, then you can try again. I normally go through posts in the mornings, and try to check a few times throughout the day, but I'm not here 24/7. There will typically be a significant delay before posts are approved. Just be patient.

Place Annotations on Map with NSDictionary/NSArray?

Hi Everyone,

Thanks for the help in advance... this one has been killing me for the past couple of hours.

I am currently pulling in a JSON feed and storing it in a NSDictionary & NSArray. I'm trying to add an annotation for each item being pulled in (time, type, latitude, and longitude). So far, I can extract each value from the Array and have them all repeat with a "for" in the console (see code below).

How to I store these values as an annotation? Any help would be great.

Below is my failed attempt...

- (void)viewDidLoad {
  [super viewDidLoad];

 // Download JSON Feed
 NSDictionary *feed = [self downloadFeed];
 NSArray *streams = (NSArray *)[feed valueForKey:@\"stream\"];


 [mapView setMapType:MKMapTypeStandard];
 [mapView setZoomEnabled:YES];
 [mapView setScrollEnabled:YES];
 MKCoordinateRegion region = { {0.0, 0.0 }, { 0.0, 0.0 } }; 
 region.center.latitude = 29.719023;
 region.center.longitude = -114.157110;
 region.span.longitudeDelta = 0.01f;
 region.span.latitudeDelta = 0.01f;
 [mapView setRegion:region animated:YES]; 

 [mapView setDelegate:self];

 int Info;
 for (Info = 0; Info < streams.count; Info++) {
  NSDictionary *stream = (NSDictionary *)[streams objectAtIndex:Info];
  NSLog(@\"Time: %@\", [stream valueForKey:@\"TheTime\"]); 
  NSLog(@\"Type: %@\", [stream valueForKey:@\"Type\"]); 
  NSLog(@\"Longitude: %@\", [stream valueForKey:@\"Longitude\"]); 
  NSLog(@\"Latitude: %@\", [stream valueForKey:@\"Latitude\"]); 

  NSString *getLat = [[NSString alloc] initWithFormat: @\"%@\", [stream valueForKey:@\"Latitude\"]];
  NSString *getLong = [[NSString alloc] initWithFormat: @\"%@\", [stream valueForKey:@\"Longitude\"]];

  NSString *getCoord = [[NSString alloc] initWithFormat: @\"{%@,%@}\", getLat, getLong];
  getCoordinates = getCoord;


  DisplayMap *ann = [[DisplayMap alloc] init]; 
  ann.title = @\"%@\", [stream valueForKey:@\"TheTime\"];
  ann.subtitle = @\"%@\", [stream valueForKey:@\"Type\"]; 
  ann.coordinate = getCoordinates;

  [mapView addAnnotation:ann];

  }
}
