Google maps 谷歌街道地图因一些错误而崩溃

我下载了适用于iOS的谷歌地图SDK以及api密钥

我导入所有框架以及GoogleMaps.framework和GoogleMaps.bundle。 在我的视图控制器中我写

static CLLocationCoordinate2D kPanoramaNear = {-33.874437, 151.207459};
- (void)loadView
 {

     CGRect applicationFrame = [[UIScreen mainScreen] bounds];
     panoView_ = [[GMSPanoramaView alloc] initWithFrame:CGRectZero];
     panoView_ = [GMSPanoramaView panoramaWithFrame:applicationFrame    nearCoordinate:kPanoramaNear];
     panoView_.backgroundColor = [UIColor grayColor];
     panoView_.delegate = self;
     panoView_.navigationLinksHidden = YES;
     panoView_.autoresizingMask = UIViewAutoresizingFlexibleHeight |   UIViewAutoresizingFlexibleWidth;

     self.view = panoView_;

    [panoView_ moveNearCoordinate:CLLocationCoordinate2DMake(-33.732, 150.312)];
}

但是我的程序崩溃了

由于未捕获的异常“NSInvalidArgumentException”而终止应用程序，原因：“+[NSData gtm_DatabyFlatingData:]：发送到类0xe79238的未识别选择器”

未识别的选择器与maps SDK的崩溃通常是由于缺少

-ObjC

链接器标志造成的：

我犯了一个小错误，我没有写-ObjC，而是写了-ObjC，谢谢
