IOS 学习笔记 AdMob Undefined symbols for architecture x86_64:"_OBJC_CLASS_$_GADMobileAds",

 

IOS在接入 AdMob广告的时候根据https://developers.google.com/admob/ios/quick-start，的步骤进行，通过pod倒入sdk之后

通过下列方式初始化，注意不能按官方文档中的引入头文件，要通过下面

#import <GoogleMobileAds/GoogleMobileAds.h>

#import <GoogleMobileAds/GoogleMobileAds.h>

@implementation AppDelegate

- (BOOL)application:(UIApplication *)application
    didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {

  [[GADMobileAds sharedInstance] startWithCompletionHandler:nil];
  return YES;
}

@end

然后运行后回报错：

Undefined symbols for architecture x86_64:"_OBJC_CLASS_$_GADMobileAds", referenced from: objc-class-ref in AppController.o

ld: symbol(s) not found for architecture x86_64

clang: error: linker command failed with exit code 1 (use -v to see invocation)

#import <GoogleMobileAds/GoogleMobileAds.h>

解决方案：

如果用CocoaPods导入的库，Build Setting->Linking->Other Linker Flags，添加$(inherited)
