ios - 使用适用于 IOS 的 Google Maps SDK 时出现 Apple Mach-O 链接器错误

Question

我正在尝试在我的应用程序中使用 Google Maps SDK。到目前为止，我已经链接了所有的框架。我很确定我已经根据 instructions 添加了适当的 -ObjC 标志.但是，当我将他们的代码复制并粘贴到我的 ViewController.m 类中时，出现以下错误:

Undefined symbols for architecture i386:
"_OBJC_CLASS_$_GMSCameraPosition", referenced from: objc-class-ref in FoothillTourViewController.o "_OBJC_CLASS_$_GMSMapView", referenced from: objc-class-ref in FoothillTourViewController.o "_OBJC_CLASS_$_GMSMarker", referenced from: objc-class-ref in FoothillTourViewController.o "_OBJC_CLASS_$_GMSServices", referenced from: objc-class-ref in FoothillTourAppDelegate.o ld: symbol(s) not found for architecture i386 clang: error: linker command failed with exit code 1 (use -v to see invocation)

"FoothillTourViewController" 是我的 ViewController 类的名称。这是我的 View Controller 类的代码。代码直接取自说明。

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

@implementation FoothillTourViewController {
    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: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_;
  }

任何帮助将不胜感激，因为我已经花了几个小时试图弄清楚发生了什么。我猜这是一个愚蠢的错误，但我不能指责它。谢谢!

更新:此答案已过时。文档现在告诉您使用 CocoaPods 而不是手动链接依赖项。

有关详细信息，请参阅 Google Developers Console .

旧答案:

Google Maps SDK 需要您链接相当多的框架。他们在这里:

• AVFoundation.framework
• 核心数据框架
• CoreLocation.framework
• CoreText.framework
• GLKit.framework
• ImageIO.framework
• libc++.dylib
• libicucore.dylib
• libz.dylib
• OpenGLES.framework
• QuartzCore.framework
• 系统配置.framework
