MapView: Tapping annotation gives me wrong detail view data? - ios

Question

I'm using an NSDictionary to populate data for my MapView annotations. However, when I tap on my MapView annotation, the detailView should display the selected user's information. That said, right now, when I tap an annotation, all detailViews display the same user's information (even though the details in the actual annotation's display bubble are correct). How can I fix this? Why won't NSDictionary allow me to do this?
MapViewController.m
NSMutableDictionary *viewParams = [NSMutableDictionary new];
[viewParams setValue:#"u000" forKey:#"view_name"];
[DIOSView viewGet:viewParams success:^(AFHTTPRequestOperation *operation, id responseObject) {
self.addressData = [responseObject mutableCopy];
for (NSMutableDictionary *multiplelocations in self.addressData) {
NSString *location = multiplelocations[#"street_address"];
NSLog(#"Pull addresses %#", location);
NSString *userNames = multiplelocations[#"users_name"];
NSString *userBio = multiplelocations[#"userbio"];
CLGeocoder *geocoder = [[CLGeocoder alloc] init];
[geocoder geocodeAddressString:location
completionHandler:^(NSArray* placemarks, NSError* error){
if (placemarks && placemarks.count > 0) {
CLPlacemark *topResult = [placemarks objectAtIndex:0];
MKPlacemark *placemark = [[MKPlacemark alloc] initWithPlacemark:topResult];
MKCoordinateRegion region = self.mapView.region;
region.span.longitudeDelta /= 8.0;
region.span.latitudeDelta /= 8.0;
MKPointAnnotation *point = [[MKPointAnnotation alloc] init];
point.coordinate = placemark.coordinate;
point.title = userNames;
point.subtitle = userBio;
[self.mapView addAnnotation:point];
}
}
];
}
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(#"Failure: %#", [error localizedDescription]);
}];
}
-(void)calloutTapped:(UITapGestureRecognizer *) sender
{
NSLog(#"Callout was tapped");
UIStoryboard *storyboard = [UIStoryboard storyboardWithName:#"Main" bundle:nil];
OtherUserViewController *yourViewController = (OtherUserViewController *)[storyboard instantiateViewControllerWithIdentifier:#"OtherUserViewController"];
NSDictionary *dictionary = [[NSDictionary alloc] init];
dictionary = [[self.addressData firstObject] mutableCopy];
yourViewController.mapuserData = dictionary;
[self.navigationController pushViewController:yourViewController animated:YES];
}
self.addressData via console
{
address = "1300 Fake Street, Vancouver, BC";
childrenunder = No;
city = Va;
"emergency facility" = Yes;
"first name" = Admin;
"last name" = Account;
phone = "Not Available";

"profile photo" = "<img typeof=\"foaf:Image\" src=\"stored/1461176121.jpg\" width=\"300\" height=\"300\" alt=\"\" />";
"property type" = House;
province = B;
"street_address" = "1300 Fake Street, Vancouver, BC";
supervision = Yes;
uid = 1;
userbio = "Need assistance? This account belongs to the team! Message us if you have any questions.";
"users_name" = Britt;
}
)

Answer 1

dictionary = [[self.addressData firstObject] mutableCopy];
Are you serious?
This should be
NSMutableDictionary *dictionary = [self.addressData mutableCopy];

Answer 2

While navigating to detail view controller, you are always getting the first object from the dictionary array.
[[self.addressData firstObject] mutableCopy];
Thats the reason you are getting the same information for all the annotation view.
Instead of that line of code, You have to identify which map marker is clicked on the MapView, for example identify the index of the dictionary array. Pick the dictionary from the array and pass it to the detail view.
