Google Maps SDK for iOS keeps increasing usage of memory

Question

I've built a simple application that shows markers on map ,and I load its x,y from JSON file from a server the markers are click-able so once you on any marker it takes you to another UIViewController (Let's name it BViewController). I've monitored the Memory Usage so each time I go back from BViewController to MapViewController (Which is the map inside) it's just double the usage of memory I tried to set it to nill or Remove it from superView , but nothing changed

My Project use ARC.

So please any idea how to reduce this usage.
Thanks in advance

If the Google Maps SDK is leaking memory there may not be much you can do. Check it's not your app first using `Instruments`. Also think about using the built-in Apple Maps instead. — Robotic Cat, Oct 18 '13 at 14:19
@RoboticCat Thanks for reply :) , I checked it for many times but this problem occurs I think because Reloading The MapView Again with deallocating the previous one do you have any idea how can I avoid re-loading — mustafa96m, Oct 18 '13 at 14:32
I'm guessing this is related to the bug report at https://code.google.com/p/gmaps-api-issues/issues/detail?id=5941 yes? If so, you could hold a reference onto the MapViewController in MyViewController and thus not need to recreate it each time you navigate into the sub view controller. — Brett, Oct 22 '13 at 04:01

I can't immediately tell what's leading to this without seeing more code, but with "expensive" objects like a GMSMapView, I might make a category to create a shared GMSMapView and add it programmatically if you're not already doing so. Your category might look something like this:

// GMSMapView+MyAdditions.h
#import <GoogleMaps/GoogleMaps.h>
@interface GMSMapView (MyAdditions)
  + (GMSMapView *)sharedMapView;
@end


// GMSMapView+MyAdditions.m
#import "GMSMapView+MyAdditions.h"
@implementation GMSMapView (MyAdditions)

+ (GMSMapView *)sharedMapView {
  static GMSMapView *mapView;
  static dispatch_once_t onceToken;
  dispatch_once(&onceToken, ^{
    CLLocation *location = [[CLLocation alloc] initWithLatitude:40.7127 longitude:-74.0059];
    GMSCameraPosition *cameraPosition = [GMSCameraPosition cameraWithLatitude:location.coordinate.latitude
                                                                    longitude:location.coordinate.longitude
                                                                         zoom:16.0];
    mapView = [GMSMapView mapWithFrame:[UIScreen mainScreen].bounds camera:cameraPosition];
  });
  return mapView;
}

@end
