How to select a map pin programmatically

Question

I am new to Maps Concept.

Please find the attached image once.

enter image description here

when i click the "pin" i am getting message says "Admire your smile" or any text..... Now i want like... when we select the table view, i need to raise that message for that pin(with out user interaction for that pin)...

I am using below code for This maps and pins.

    -(void) viewWillAppear:(BOOL)animated
{
[super viewWillAppear:YES];
customLocation.latitude=[casesobjc.latitude_string doubleValue];
        customLocation.longitude=[casesobjc.longitude_string doubleValue];
 MapViewAnnotation *newAnnotation = [[MapViewAnnotation alloc] initWithTitle:casesobjc.locationForMap_string andCoordinate:customLocation];
[mapView addAnnotation:newAnnotation];
}
- (MKAnnotationView *) mapView: (MKMapView *) mapView viewForAnnotation: (id<MKAnnotation>) annotation {
 MKPinAnnotationView *pin = (MKPinAnnotationView *) [mapView dequeueReusableAnnotationViewWithIdentifier: @"annotation_ID"];
if (pin == nil) {
        pin = [[MKPinAnnotationView alloc] initWithAnnotation: annotation reuseIdentifier: @"annotation_ID"];
    } else {
        pin.annotation = annotation;
    }
    pin.pinColor = MKPinAnnotationColorPurple;
    pin.animatesDrop = YES;
    pin.canShowCallout=YES;
return pin;
}

Now i will show all the pins once like below.

i did not understand?... i used this code but not works.. i.e., customLocation.latitude=appdelegate.appDelegateLatitude; customLocation.longitude=appdelegate.appDelegateLongitude; MapViewAnnotation *newAnnotation = [[MapViewAnnotation alloc] initWithTitle:casesobjc.locationForMap_string andCoordinate:customLocation]; [mapView selectAnnotation:newAnnotation animated:YES]; @Spynet — Babul, Apr 02 '13 at 07:22
Just pass the title name when the row is selected and set the title for annotation — Sugan S, Apr 02 '13 at 07:27
i set the titles.. which method i need to call. i set the titles for all pins like this MapViewAnnotation *newAnnotation = [[MapViewAnnotation alloc] initWithTitle:casesobjc.locationForMap_string andCoordinate:customLocation]; @sugan.s — Babul, Apr 02 '13 at 07:29
what is casesobjec.location and what u get in tableviewDidSelectedRowAtIndexPath @Babul — Sugan S, Apr 02 '13 at 07:32
I am loading static data (different location names with respective latitude and longitude)... when i select the table view i get an array with objects that is caseObject. It contains the title, latitude, longitude . @sugan.s — Babul, Apr 02 '13 at 07:37
by using [mapView selectAnnotation:newAnnotation animated:YES]; this one you can't get your requirement? — Balu, Apr 02 '13 at 08:56
try like this [mapView selectAnnotation:[[mapView annotations] objectAtIndex:1] animated:YES]; may be it'l help you. — Balu, Apr 02 '13 at 09:05
i write code like this .. customLocation.latitude=appdelegate.appDelegateLatitude; customLocation.longitude=appdelegate.appDelegateLongitude; MapViewAnnotation *newAnnotation = [[MapViewAnnotation alloc] initWithTitle:casesobjc.locationForMap_string andCoordinate:customLocation]; [mapView selectAnnotation:newAnnotation animated:YES]; @Sunny — Babul, Apr 02 '13 at 09:07
Take a look at http://stackoverflow.com/questions/978897/how-to-trigger-mkannotationviews-callout-view-without-touching-the-pin — Krish Allamraju, Apr 02 '13 at 09:16
Hi @Babul Have you found a solution to this issue yet? I think I have quite [a similar issue](http://stackoverflow.com/questions/28144466/how-to-select-map-pin-when-tapping-table-row-that-associates-with-it). Could you please share the solution with me? Thanks. — SanitLee, Jan 29 '15 at 05:45

The method that you are looking for is selectAnnotation:.

In your didSelectRowAtIndexPath, you have to find the annotation associated with the table row.

Once you find it, you can tell it, to select it by using:

[mapView selectAnnotation:foundAnnotation animated:YES];

I think I have quite a similar issue. Could you please help take a look into my [question](http://stackoverflow.com/questions/28144466/how-to-select-map-pin-when-tapping-table-row-that-associates-with-it) also? I just cannot figure it out especially on how to find the annotation associated with the table row. – SanitLee Jan 27 '15 at 14:16

The same as the Objective C answer, in your tableview you have a list of annotations. In Swift in the didSelectRow:

For Swift 4:

// annotations would be the array of annotations - change to your required data sets name
let selectedAnnotation = annotations[indexPath.row]
self.mapView.selectAnnotation(selectedAnnotation, animated: true)

Short and simple.
