iphone - libGoogleAnalytics.a 与 iPhone iOS4 模拟器的链接问题

Question

我最近升级到了 iOS4 SDK，我的应用程序不再针对模拟器进行编译，但确实针对设备进行编译。

这是由第 3 方库 libGoogleAnalytics.a 造成的。解决方案似乎是谷歌发布一个符合新SDK的新静态库，不幸的是没有任何发布日期的消息，并且由于新SDK许可，他们可能永远不会发布新库。

我收到以下编译错误:

Google 论坛上的一个建议是创建 GANTracker 类的虚拟实现以在模拟器中使用。即创建一个文件GANTracker_stub.m:

#import "GANTracker.h"

#if TARGET_IPHONE_SIMULATOR

@implementation GANTracker

+ (GANTracker *)sharedTracker
{
    return [[[GANTracker alloc] init] autorelease];
}

- (void)startTrackerWithAccountID:(NSString *)accountID
               dispatchPeriod:(NSInteger)dispatchPeriod
                     delegate:(id<GANTrackerDelegate>)delegate
{
}

- (void)stopTracker
{  
}

- (BOOL)trackPageview:(NSString *)pageURL
        withError:(NSError **)error
{
    return YES;
}

- (BOOL)trackEvent:(NSString *)category
        action:(NSString *)action
         label:(NSString *)label
         value:(NSInteger)value
     withError:(NSError **)error
{
    return YES;
}

- (BOOL)dispatch
{
    return YES;
}

@end
#endif

但这对我不起作用，我缺少什么吗？

通过 Google Analytics 论坛找到的解决方案:

用途:


lipo libGoogleAnalytics.a -删除 i386 -输出 libGoogleAnalytics2.a


然后从您的项目中删除 libGoogleAnalytics.a 并添加 libGoogleAnalytics2.a

这只能与 GANTracker 的虚拟实现结合使用，如上所示。
