iOS, How to use GMSCoordinateBounds to show all the markers of the map?

Question

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

Answer 1

- (void)focusMapToShowAllMarkers
{

    GMSCoordinateBounds *bounds = [[GMSCoordinateBounds alloc] init];

    for (GMSMarker *marker in )
        bounds = [bounds includingCoordinate:marker.position];

    [ 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]];

This is my result:
