I have a set of annotations that are supposed to take you to a new view and display parse information on it. I do not believe that the new view is grabbing the objectId of each geopoint though because the label is not working.
Here is my code:
- (MKAnnotationView *)mapView:(MKMapView *)aMapView viewForAnnotation:(id<MKAnnotation>)annotation {
// Let the system handle user location annotations.
if ([annotation isKindOfClass:[MKUserLocation class]]) {
return nil;
}
static NSString *pinIdentifier = #"CustomPinAnnotation";
// Handle any custom annotations.
if ([annotation isKindOfClass:[PAWPost class]])
{
// Try to dequeue an existing pin view first.
MKPinAnnotationView *pinView = (MKPinAnnotationView*)[aMapView dequeueReusableAnnotationViewWithIdentifier:pinIdentifier];
if (!pinView)
{
// If an existing pin view was not available, create one.
pinView = [[MKPinAnnotationView alloc] initWithAnnotation:annotation
reuseIdentifier:pinIdentifier];
}
else {
pinView.annotation = annotation;
}
static NSString* BridgeAnnotationIdentifier = #"bridgeAnnotationIdentifier";
MKPinAnnotationView *customPinView = [[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:BridgeAnnotationIdentifier];
pinView.pinColor = MKPinAnnotationColorPurple;
pinView.animatesDrop = YES;
pinView.canShowCallout = YES;
pinView.rightCalloutAccessoryView = [UIButton buttonWithType:UIButtonTypeDetailDisclosure];
return pinView;
}
return nil;
}
And here is the push to the new View.
- (void)mapView:(MKMapView *)mapView annotationView:(MKAnnotationView *)view calloutAccessoryControlTapped:(UIControl *)control
{
DetailViewController *objDetail = [[DetailViewController alloc] initWithNibName:#"DetailViewController" bundle:nil];
objDetail.pawpost = (PAWPost *)view.annotation;
[self.navigationController pushViewController:objDetail animated:YES];
}
And here is the Code on the new View page.
[super viewDidLoad];
PFObject *gameScore = [PFObject objectWithClassName:#"Arcade"];
self.title = #"Detail View";
PFQuery *query = [PFQuery queryWithClassName:#"Arcade"];
NSString *objectId = gameScore.objectId;
[query getObjectInBackgroundWithId:ObjectIdentifier block:^(PFObject *gameScore, NSError *error) {
lblTitle.text = gameScore[#"name"];
NSLog(#"%#", gameScore);
}];

I have a an array of latitude and longitude and using for loop am displaying the MKPointAnnotation on the map. I want to show a view as a popup with data when the specific MKPointAnnotation is tapped.
Here is my code -
- (void)mapView:(MKMapView *)mapView didUpdateUserLocation:(MKUserLocation *)userLocation {
MKCoordinateRegion region = MKCoordinateRegionMakeWithDistance(userLocation.coordinate, 10000, 10000);
[self.mapView setRegion:[self.mapView regionThatFits:region] animated:YES];
[_locationManager stopUpdatingLocation];
NSArray *set = [[NSArray alloc] init];
for (int i = 0; i < _json.count; i++) {
_name = [_json[i] valueForKey:#"name"];
_class = [_json[i] valueForKey:#"class"];
set = [_json[i] valueForKey:#"set"];
if (setFreeHour.count != 0) {
for (int j=0;j<set.count;j++) {
NSDictionary *dict = [[NSDictionary alloc] init];
dict = set[j];
_lat = dict[#"latitude"];
_longi = dict[#"longitude"];
CLLocationCoordinate2D coordinate;
coordinate.latitude = [_lat doubleValue];
coordinate.longitude = [_longi doubleValue];
// Add an annotation
MKPointAnnotation *point1 = [[MKPointAnnotation alloc] init];
point1.coordinate = CLLocationCoordinate2DMake(coordinate.latitude, coordinate.longitude);
point1.title = _name;
point1.subtitle = _class;
[self.mapView addAnnotation:point1];
}
}
}
}
- (MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id <MKAnnotation>)annotation {
if ([annotation isKindOfClass:[MKUserLocation class]])
return nil;
// Handle any custom annotations.
if ([annotation isKindOfClass:[MKPointAnnotation class]]) {
// Try to dequeue an existing pin view first.
MKAnnotationView *pinView = (MKAnnotationView*)[mapView dequeueReusableAnnotationViewWithIdentifier:#"CustomPinAnnotationView"];
if (!pinView) {
// If an existing pin view was not available, create one.
pinView = [[MKAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:#"CustomPinAnnotationView"];
pinView.canShowCallout = YES;
pinView.image = [UIImage imageNamed:#"annotation"];
pinView.calloutOffset = CGPointMake(0, 0);
UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc] initWithTarget:self action:#selector(showDetails)];
[pinView addGestureRecognizer:tap];
} else {
pinView.annotation = annotation;
}
return pinView;
}
return nil;
}
- (void)showDetails{
self.popup.hidden = NO;
}
//PS: popup is a view that contains labels. I want to pass data from MKPointAnnotation to the view
Why don't you use mapView(_:didSelect:) method instead of UITapGestureRecognizer?
(void)mapView:(MKMapView *)mapview didSelectAnnotationView:(MKAnnotationView *)view {
// 1. get data from view(MKAnnotationView)
// 2. pass data to another view
}

I am trying to create custom annotation as each annotation save some data which i need to show on tap of pin. But i need to show default ios pin image. Everything is working fine but pin will only show when i set any image. without setting image it is not showing default ios pin. My code is
CustomAnnotation.h file
#interface CustomAnnotation : NSObject<MKAnnotation>
#property(nonatomic,strong)NSString *title;
#property(nonatomic,strong)NSString *subTitle;
#property(nonatomic)CLLocationCoordinate2D coordinate;
#property(nonatomic,strong) UserDevice *userData;
-(instancetype)initWithUserData:(UserDevice *)userData;
on mapViewC.h
-(void)addMarkersOnMap{
for (UserDevice* userDevice in markersArray) {
CustomAnnotation *point = [[CustomAnnotation alloc]initWithUserData:userDevice];
point.coordinate = CLLocationCoordinate2DMake(userDevice.latitude, userDevice.longitude);
point.userData = userDevice;
point.title = #"dszf";
[mapview addAnnotation:point];
MKMapRect mapRect = [self getZoomingRectOnMap:mapview toFitAllOverlays:YES andAnnotations:YES includeUserLocation:NO];
[mapview setVisibleMapRect:mapRect edgePadding:UIEdgeInsetsMake(10.0, 10.0, 10.0, 10.0) animated:YES];
}
}
#pragma mark - MKMapView Delegate methods
- (MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id<MKAnnotation>)annotation {
if ([annotation isKindOfClass:[MKUserLocation class]]) {
return nil;
}
if ([annotation isKindOfClass:[CustomAnnotation class]]) {
CustomAnnotation *customAnnotation = annotation;
MKAnnotationView *customAnnotationView = (MKAnnotationView *)[mapView dequeueReusableAnnotationViewWithIdentifier:#"annotationViewID"];
if (customAnnotationView == nil){
customAnnotationView = [[MKAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:#"annotationViewID"];
}
// customAnnotationView.image = [UIImage imageNamed:#"pin-1"];
customAnnotationView.canShowCallout = true;
customAnnotationView.annotation = customAnnotation;
return customAnnotationView;
}
return nil;
}
Instead of CustomAnnotationView use MKPinAnnotationView in your viewForAnnotation MKMapViewDelegate method
- (MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id<MKAnnotation>)annotation {
if ([annotation isKindOfClass:[MKUserLocation class]]) {
return nil;
}
if ([annotation isKindOfClass:[CustomAnnotation class]]) {
CustomAnnotation *customAnnotation = annotation;
MKPinAnnotationView *customAnnotationView = (MKPinAnnotationView *)[mapView dequeueReusableAnnotationViewWithIdentifier:#"annotationViewID"];
if (customAnnotationView == nil){
customAnnotationView = [[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:#"annotationViewID"];
}
// customAnnotationView.image = [UIImage imageNamed:#"pin-1"];
customAnnotationView.canShowCallout = true;
customAnnotationView.annotation = customAnnotation;
return customAnnotationView;
}
return nil;
}
Hope this helps
CustomAnnotation *customAnnotation = annotation;
NSString *annotationIdentifier = #"PinViewAnnotation";
MKPinAnnotationView *pinView = (MKPinAnnotationView*)[mapView dequeueReusableAnnotationViewWithIdentifier: annotationIdentifier];
if (pinView ==nil) {
pinView = [[MKPinAnnotationView alloc]initWithAnnotation: customAnnotation reuseIdentifier: annotationIdentifier];
}
pinView.pinColor = MKPinAnnotationColorGreen; // change color
pinView.canShowCallout = YES;
pinView.enabled = YES;
mapView selectAnnotation:pinView animated:YES];
I have several annotation points. What I want to do is when I click an annotation point I want to display that data. I have a custom Annotation class with a title and an NSDictionary. The dictionary contains an image URL and ID. I want to fetch these when I click on a specific annotation.
EDIT: I know about the didSelectAnnotation, but how do I access the data?
-(void)annotations{
CLLocationCoordinate2D pinPoint;
for (NSDictionary * dict in _dataArray) {
pinPoint.latitude =[[dict valueForKey:#"lat"] doubleValue];
pinPoint.longitude = [[dict valueForKey:#"lng"] doubleValue];
_myAnnotation = [[MapViewAnnotation alloc]initWithTitle:[dict valueForKey:#"name"]andCoordinate:pinPoint andData:dict];
MKPlacemark *placemark = [[MKPlacemark alloc] initWithCoordinate:pinPoint addressDictionary:nil] ;
_destination = [[MKMapItem alloc] initWithPlacemark:placemark];
_myAnnotation.title=[dict valueForKey:#"name"];
[self.mapKit addAnnotation:_myAnnotation];
}
}
- (void)mapView:(MKMapView *)mapView didUpdateUserLocation:(MKUserLocation *)userLocation
{
MKCoordinateRegion region = MKCoordinateRegionMakeWithDistance(userLocation.coordinate, 800, 800);
[self.mapKit setRegion:[self.mapKit regionThatFits:region] animated:YES];
}
- (MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(MapViewAnnotation*)annotation
{
// If it's the user location, just return nil.
if ([annotation isKindOfClass:[MKUserLocation class]])
return nil;
// Handle any custom annotations.
if ([annotation isKindOfClass:[MapViewAnnotation class]])
{
// Try to dequeue an existing pin view first.
MKAnnotationView *pinView = (MKAnnotationView*)[mapView dequeueReusableAnnotationViewWithIdentifier:#"CustomPinAnnotationView"];
if (!pinView)
{
// If an existing pin view was not available, create one.
pinView = [[MKAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:#"CustomPinAnnotationView"];
pinView.canShowCallout = YES;
NSLog(#"%#",[annotation.data valueForKey:#"name"]);
pinView.image = [UIImage imageNamed:#"image"];
pinView.calloutOffset = CGPointMake(0, 32);
UIButton* rightButton = [UIButton buttonWithType:UIButtonTypeDetailDisclosure];
pinView.rightCalloutAccessoryView = rightButton;
} else {
pinView.annotation = annotation;
}
return pinView;
}
return nil;
}
-(void)mapView:(MKMapView *)mapView annotationView:(MKAnnotationView *)view calloutAccessoryControlTapped:(UIControl *)control {
MKDirectionsRequest *request = [[MKDirectionsRequest alloc] init];
[request setTransportType:MKDirectionsTransportTypeWalking];
request.source = [MKMapItem mapItemForCurrentLocation];
request.destination = _destination;
request.requestsAlternateRoutes = NO;
MKDirections *directions =
[[MKDirections alloc] initWithRequest:request];
[directions calculateDirectionsWithCompletionHandler:
^(MKDirectionsResponse *response, NSError *error) {
if (error) {
// Handle Error
} else {
[self showRoute:response];
}
}];
}
EDIT 2nd :
-(void)mapView:(MKMapView *)mapView didSelectAnnotationView:(MKAnnotationView *)view
{
MapViewAnnotation * annotation = (MapViewAnnotation *) view;
NSLog(#"%#",[annotation.data valueForKey:#"name"]);
NSURL *url =[NSURL URLWithString:[[NSUserDefaults standardUserDefaults] objectForKey:#"SPOTTD_profilePic"]];
NSData *imageData = [NSData dataWithContentsOfURL:url];
_imgMyProfile.image = [UIImage imageWithData:imageData];
}
You can use the didSelectAnnotationView method, in combination with the annotation property of the MKAnnotationView:
- (void)mapView:(MKMapView *)mapView didSelectAnnotationView:(MKAnnotationView *)view
if ([view.annotation isKindOfClass:[MapViewAnnotation class]]) {
MapViewAnnotation *annotation = (MapViewAnnotation)view.annotation;
}
}
After you have safely cast the annotation to your custom type, you can access its properties like the NSDictionary.
- (void)mapView:(MKMapView *)mapView annotationView:(MKAnnotationView *)view calloutAccessoryControlTapped:(UIControl *)control
{
NSString *latPoint2 = [NSString stringWithFormat:#"%.6f", view.annotation.coordinate.latitude];
NSString *longPoint2 =[NSString stringWithFormat:#"%.6f", view.annotation.coordinate.longitude];
There is one more method for annotation which is
- (void)mapView:(MKMapView *)mapView didSelectAnnotationView:(MKAnnotationView *)view
{}.In this method you can show your data on click of annotation.Hope this will help you. If any query let me know. Thanks
I am new to xcode and i hope someone can help me with my code, and point me how to solve my issue. i've been looking at the internet, but really i couldnt figure it out.
How can i go from a map view to a detail view, bringing the "ID" of the pin with it and print it in a label.
when i click on the arrow for the annotation, my simulator crashes.
Please any ideas, how to approach it and solve it ?
( basicly i want to get the ID of the pin, and send it to a server through JSON and then move to the Detailview, but the next step )
Here is what i did so far :
My Location.m ( view controller for the map )
#import "My_Location.h"
#import "DetailViewController.h"

CLLocationCoordinate2D location;
for (NSDictionary *dictionary in array)
{
MKPointAnnotation *newAnnotation = [[MKPointAnnotation alloc] init];
location.latitude = [dictionary[#"lat"] doubleValue];
location.longitude = [dictionary[#"lon"] doubleValue];
newAnnotation.title = dictionary[#"name"];
newAnnotation.coordinate = location;
[newAnnotations addObject:newAnnotation];
[newAnnotation release];
}
[self.MyLocation addAnnotations:newAnnotations];

}
}
Take_Photo is my detailviewcntroller.
And my storybaord look like this :
Mylocation View controller -> ( Segue: identifier ( Take_Photo )) -> Take_Photo view Controller
trying to pass my annotation's data (name, address, phone #, url, description, etc) to a DetailViewController with a table. stuck----please read the code. the data isnt passed with calloutAccessoryTapped. Help?

mapItem exists in the for loop of your gasButton function, no where else as far as I can see. You've created an annotation (zip) and added it to your map. In viewForAnnotation you are given that annotation as a parameter and asked to make an annotationView from it. In calloutAccessoryControlTapped you are given an annotationView and told it has been tapped. You need to follow the chain back to your data. From the annotationView get the annotation and from the annotation get your name.
MKMapView *)mapView annotationView:(MKAnnotationView *)view calloutAccessoryControlTapped:(UIControl *)control
{
NSLog(#"%# - tapped", view.annotation.title);
}
