谷歌地图SDK教程崩溃

Question

我正试图在iOS应用程序中设置谷歌地图，但遇到InvalidArgumentException。

一些人已经提出了同样的问题；然而，他们要么没有得到有用的回应，要么给出的回应没有解决问题。

代码直接从谷歌的入门页面复制：

#import "XXMapViewController.h"
#import <GoogleMaps/GoogleMaps.h>
@interface XXMapViewController ()
@end
@implementation XXMapViewController{
    GMSMapView *mapView_;
}
- (void)viewDidLoad
{
    [super viewDidLoad];
    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_;
    // Do any additional setup after loading the view, typically from a nib.

}
@end

这是它崩溃的线路，所以我已经确定设置视图没有问题：

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

这是堆栈跟踪（为了匿名起见，应用程序名称为X’d out）：

我已经将-OjC标志添加到我的项目中，并按照其他人的建议尝试将其添加到目标中；但是，将其添加到目标会导致构建失败。我还创建了一个新的单视图项目，当遵循完全相同的说明时，它运行良好。我有正确的API密钥，iOS版谷歌地图在我的API控制台中启用。这非常令人沮丧，是我完成项目的一堵巨大的墙。如果有人能给我指明正确的方向，我将不胜感激

这是与Parse依赖项的冲突。解决方案是要么消除FB SDK依赖项，要么只下载SDK。我选择了后者，因为我将不可避免地在我的应用程序中使用它。
