我是 Objective-C 编程的新手。我正在为一个项目做“google map sdk tutorial”。但它一直给我带来这个错误：

2013-09-08 21:49:14.670 map-sdk-test1[709:c07] +[GMSCameraPosition cameraWithLatitude:longitude:zoom:]: unrecognized selector sent to class 0x2fcc40

libc++abi.dylib: terminate called throwing an exception

这是我正在做的教程：https://developers.google.com/maps/documentation/ios/start

我一步一步地跟着它。

这是发生错误的代码：

    #import "ViewController.h"
    #import <GoogleMaps/GoogleMaps.h>

    @implementation ViewController {
    GMSMapView *mapView_;
    }

    // You don't need to modify the default initWithNibName:bundle: method.

    - (void)loadView {
    // Create a GMSCameraPosition that tells the map to display the
   // coordinate -33.86,151.20 at zoom level 6.
   GMSCameraPosition *camera = [GMSCameraPosition cameraWithLatitude:-33.86
                                                             longitude:151.20 zoom:5];


     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.
     }

      - (BOOL)shouldAutorotateToInterfaceOrientation:     (UIInterfaceOrientation)interfaceOrientation
     {
      return (interfaceOrientation != UIInterfaceOrientationPortraitUpsideDown);
      }

       @end

【问题讨论】：

能否贴出部分代码，出现错误的地方？
@RaúlJuárez 我发布了代码
我在构建设置中解决了 :) ：其他链接器标志；我添加了这个 -all_load

我今天看到了这个问题。问题是我错过了在其他链接器标志中添加 -ObjC 标志的步骤。
