将Google Analytics添加到iOS应用程序会导致错误

Question

我添加了GAI框架.

档案:

- GAI.h - GAIDictionaryBuilder.h - GAIFields.h GAILogger.h - GAITrackedViewController.h - GAITracker.h - libGoogleAnalytics_debug.a

但是,当我尝试构建项目时,它显示了这样的错误:

Undefined symbols for architecture i386:

      ___llvm_gcov_writeout in libGoogleAnalytics_debug.a(GAI.o)

ld:找不到架构i386 clang的符号:错误:链接器命令失败,退出代码为1(使用-v查看调用)

是什么导致了这个错误

更新:

// AppDelegate.h

@property (nonatomic, retain) id<GAITracker> tracker;

// AppDelegate.m

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


[GAI sharedInstance].optOut = YES;
[GAI sharedInstance].dispatchInterval = 120;
[GAI sharedInstance].trackUncaughtExceptions = YES;
self.tracker = [[GAI sharedInstance] trackerWithName: kTrackerName
                                          trackingId: kTrackingId];

//other code 

return YES;
}

Answer 1

我有同样的错误:只需将"libGoogleAnalyticsServices.a"添加到您的文件中,如下所示:

我希望这可以帮到你.这对我有用;)

Answer 2

除了README文件中指定的所有库和框架之外,您还需要在编译模拟器时包含AdSupport.framework和libGoogleAnalyticsServices.a(而不是libGoogleAnalytics_debug.a)以消除构建错误.

Answer 3

您必须添加这些类：

如果你添加这些，它会工作得很好。

我认为最好的是如果你设置：

[GAI sharedInstance].dispatchInterval = 0;
