Google Maps animateToCameraPosition iOS7 issue

Question

I am trying to install Google Maps API to an app for iOS7. After following Google's guidelines and videos I ended up with the following error: [GMSMapView animateToCameraPosition:]: unrecognized selector sent to instance 0x10b98e6c0

I am using Storyboard, and trying to make this map appears above a TableView in the same viewController.

In this app, I use Parse, which is fetching data to my TableView, and is working fine.

I tried to use a couple of suggestions which I found here on StackOverflow, but the problem persists:

Cannot put a google maps GMSMapView in a subview of main main view?

How to set the frame for mapview - in google GMSMap for iOS6

Apparently the issue is related to this method:

mapView_ = [GMSMapView mapWithFrame:CGRectZero camera:camera];

When I erases it, the error goes away.

My TestViewController is coded as below(no table or anything, but still not working):

//  TesteViewController.m

//



#import "TesteViewController.h"
#import <GoogleMaps/GoogleMaps.h>
#import "AppDelegate.h"

@interface TesteViewController ()

@end

@implementation TesteViewController{
    GMSMapView *mapView_;
}

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
    self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
    if (self) {
        // Custom initialization
    }
    return self;
}

- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view.


    // Create a GMSCameraPosition that tells the map to display the
    GMSCameraPosition *camera = [GMSCameraPosition cameraWithLatitude:-33.86
                                                            longitude:151.20
                                                                 zoom:6];
    mapView_ = [GMSMapView mapWithFrame:CGRectZero camera:camera];
    mapView_.myLocationEnabled = YES;
    self.view = mapView_;

    // Creates a marker in the center of the map.
    GMSMarker *marker = [[GMSMarker alloc] init];
    marker.position = CLLocationCoordinate2DMake(-33.86, 151.20);
    marker.title = @"Sydney";
    marker.snippet = @"Australia";
    marker.map = mapView_;




}



- (void)didReceiveMemoryWarning
{
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}



@end

I also imported all frameworks, as recommended, and did put -ObjC into my otherLinkerFlags, without success.

In addition to that, I tested the process I am using in a new blank project and it worked fine, but, when I try to add a blank viewController just as a test to the original project, it does not work.

Another test I did, was to add a view to this blank viewController and try what is stated on StackOverflow's references I posted above.

Has anyone got any suggestions about what is happening?

Maybe a conflict with Parse's framework or some other library?

Instead of using -ObjC I also tried -force_load $(PROJECT_DIR)/GoogleMaps.framework/GoogleMaps and the error goes away, it asks me to allow my current position, but the screen does not load.

don't set the view in viewDidLoad! That is the job of loadView. So move the map view creation code to the loadView method. — Felix
@phix23 Tried with loadView, but got the same error. In addition I tried to move it to viewWillLayoutSubviews method, the error disappears, but I got only a black view. — Joao Paulo
Where are you putting the code that is causing the crash - i.e. [GMSMapView animateToCameraPosition:]? — Adam
@Adam I tried both, viewDidLoad and loadView as phix23 suggested. Interesting that when I put -force_load $(PROJECT_DIR)/GoogleMaps.framework/GoogleMaps the crash goes away, it asks my current location, but it does not load my view. It keeps loading until gets a memory crash. — Joao Paulo
Don't replace self.view with mapView_ - instead, add mapView_ as a subview to self.view — Adam

What you have to do is to add -objC flag in your "project" build setting, instead of "target"'s build setting.

As it is mentioned in the following section from Google's Documentation

**" Choose your project, rather than a specific target, and open the
    Build Settings tab. In the Other Linker Flags section, add -ObjC. If
    these settings are not visible, change the filter in the Build
    Settings bar from Basic to All. "**

By this way, I was able solve Google Maps animateToCameraPosition issue.
