I want to show all the markers that are on my map, after doing some searches I found that it should be done with GMSCoordinateBounds (Google Maps SDK) I've read the official documentation about it, but I have not understand how to use it and implement it in my code.
https://developers.google.com/maps/documentation/ios/reference/interface_g_m_s_camera_update#aa5b05606808272f9054c54af6830df3e
Here is my code
GMSCoordinateBounds *bounds = [[GMSCoordinateBounds alloc] init]; CLLocationCoordinate2D location; for (NSDictionary *dictionary in array) { location.latitude = [dictionary[@"latitude"] floatValue]; location.longitude = [dictionary[@"longitude"] floatValue]; // Creates a marker in the center of the map. GMSMarker *marker = [[GMSMarker alloc] init]; marker.icon = [UIImage imageNamed:(@"marker.png")]; marker.position = CLLocationCoordinate2DMake(location.latitude, location.longitude); bounds = [bounds includingCoordinate:marker.position]; marker.title = dictionary[@"type"]; marker.map = mapView_; } [mapView_ animateWithCameraUpdate:[GMSCameraUpdate fitBounds:bounds withPadding:30.0f]];
Any help ?
You can remove a marker from the map by setting the map property of the GMSMarker to nil .
- (void)focusMapToShowAllMarkers { GMSCoordinateBounds *bounds = [[GMSCoordinateBounds alloc] init]; for (GMSMarker *marker in <An array of your markers>) bounds = [bounds includingCoordinate:marker.position]; [<yourMap> animateWithCameraUpdate:[GMSCameraUpdate fitBounds:bounds withPadding:30.0f]]; }
UPDATE:
are you sure there is nothing wrong in you array of markers and the coordinates? I've tried this code and is working perfectly. I've put this on the viewDidAppear
NSMutableArray *array = [[NSMutableArray alloc]initWithObjects:[[NSDictionary alloc]initWithObjectsAndKeys:@"44.66",@"latitude",@"21.33",@"longitude", nil], [[NSDictionary alloc]initWithObjectsAndKeys:@"44.66",@"latitude",@"21.453",@"longitude", nil], [[NSDictionary alloc]initWithObjectsAndKeys:@"44.44",@"latitude",@"21.993",@"longitude", nil], [[NSDictionary alloc]initWithObjectsAndKeys:@"44.635",@"latitude",@"21.553",@"longitude", nil], [[NSDictionary alloc]initWithObjectsAndKeys:@"44.3546",@"latitude",@"21.663",@"longitude", nil], [[NSDictionary alloc]initWithObjectsAndKeys:@"44.6643",@"latitude",@"21.212",@"longitude", nil], [[NSDictionary alloc]initWithObjectsAndKeys:@"44.63466",@"latitude",@"21.3523",@"longitude", nil],nil]; GMSCoordinateBounds *bounds = [[GMSCoordinateBounds alloc] init]; CLLocationCoordinate2D location; for (NSDictionary *dictionary in array) { location.latitude = [dictionary[@"latitude"] floatValue]; location.longitude = [dictionary[@"longitude"] floatValue]; // Creates a marker in the center of the map. GMSMarker *marker = [[GMSMarker alloc] init]; marker.icon = [UIImage imageNamed:(@"marker.png")]; marker.position = CLLocationCoordinate2DMake(location.latitude, location.longitude); bounds = [bounds includingCoordinate:marker.position]; marker.title = dictionary[@"type"]; marker.map = mapView_; } [mapView_ animateWithCameraUpdate:[GMSCameraUpdate fitBounds:bounds withPadding:30.0f]];
