ios - 谷歌地图 iOS SDK 崩溃

Question

我将 google maps iOS SDK 与 Storyboard一起使用。以导航 View Controller 开始的应用程序具有带 map 的 Root View Controller 。

@implementation MyViewController
@synthesize btnMyLock;
@synthesize btnNearby;

GMSMapView *mapView_;
- (void)viewDidLoad
{
    [super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
GMSCameraPosition *camera = [GMSCameraPosition cameraWithLatitude:20
                                                        longitude:20
                                                             zoom:0];

     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 setIcon:[UIImage imageNamed:@"pin"]];
     marker.position = CLLocationCoordinate2DMake(-33.86, 151.20);
     marker.title = @"Sydney";
     marker.snippet = @"Australia";
     marker.map = mapView_;

     mapView_.settings.compassButton = YES;

     [mapView_ addSubview:btnMyLock];
     [mapView_ addSubview:btnNearby]; 
}

按钮 btnMyLock 推送 TableView Controller 。在 iOS 7 中没问题。但是 iOS 6 我的应用程序崩溃了。有时会因 EXC_BAD_ACCESS (code=1) 或 code=2 而崩溃

我使用自动布局 View 的问题。
