ios google maps plotting multiple markers issues(info window and marker repeating)

Question

First i create a Map with user location

-(void)initGogleMapView{

GMSCameraPosition *camera = [GMSCameraPosition cameraWithLatitude:currentLocation.coordinat         


        

Answer 1

First of all check your Latitude and Longitude in array, it might be duplicates. Otherwise, follow steps :

At very first, add GoogleMaps.bundle and GoogleMaps.framework to your project. And then when you want to implement google map, #import <GoogleMaps/GoogleMaps.h>, then set delegate @interface YourViewController : UIViewController <GMSMapViewDelegate>.

Declare property in your .h

@property (nonatomic, retain) GMSMapView *gMapView;

In viewDidLoad()

GMSCameraPosition *camera = [GMSCameraPosition cameraWithLatitude:appDelegate.currentLoc.coordinate.latitude longitude:appDelegate.currentLoc.coordinate.longitude zoom:6];
self.gMapView = [GMSMapView mapWithFrame:CGRectZero camera:camera];
self.gMapView.delegate = self;
self.gMapView.myLocationEnabled = YES;
self.gMapView.mapType = kGMSTypeSatellite;
self.view = self.gMapView;

GMSMarker *curLocation = [[GMSMarker alloc] init];
curLocation.title = @"Current Location";
curLocation.appearAnimation = kGMSMarkerAnimationPop;
curLocation.position = CLLocationCoordinate2DMake(appDelegate.currentLoc.coordinate.latitude, appDelegate.currentLoc.coordinate.longitude);
curLocation.map = self.gMapView;

Where you have added multiple markers to map.

for(int i=0;i<[latLongArr count];i++)
{
   GMSMarker *marker = [[GMSMarker alloc] init];
   marker.position = CLLocationCoordinate2DMake([[(NSDictionary *)[latLongArr objectAtIndex:i] valueForKey:@"Latitude"] doubleValue], [[(NSDictionary *)[latLongArr objectAtIndex:i] valueForKey:@"Longitude"] doubleValue]);
   marker.appearAnimation = kGMSMarkerAnimationPop;
   marker.title = @"Title";
   marker.snippet = @"Sub title";
   marker.map = self.gMapView;
}
