libGoogleAnalytics.a鏈接問題與iPhone iOS4模擬器

我最近升級到iOS4 SDK和我的應用程序不再編譯爲模擬器，但確實爲設備編譯。libGoogleAnalytics.a鏈接問題與iPhone iOS4模擬器

這是由於第三方庫libGoogleAnalytics.a。該解決方案似乎是爲了發佈一個新的符合新SDK的靜態庫，遺憾的是沒有任何發佈日期，並且由於新的SDK許可，他們可能永遠不會發布新的庫。

我正在以下編譯錯誤：

一個在谷歌論壇的建議是創建一個虛擬實現GANTracker類的在模擬器中使用。即創建一個文件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

然而，這是不是爲我工作，是有什麼我失蹤？通過谷歌分析論壇發現

使用Google Analytics for iOS 0.8 SDK可以解決此問題。我今天就試了。

解決方案：

用途：

lipo libGoogleAnalytics.a -remove i386 -output libGoogleAnalytics2.a

然後從你的項目中刪除libGoogleAnalytics.a並添加libGoogleAnalytics2.a會同

這隻能如上所示的GANTracker的虛擬實現。

不錯的發現！這也是我的問題。 – 2010-06-28 18:25:23

會開始另一個問題，但是，你會很好地說*你對GANTracker_stub.m做了什麼？論壇上的人們說要將代碼複製到GANTracker_stub.m中，但接下來不做什麼？使用-remove i386解決方案在我看來似乎不允許在SIM下運行？ – Jann 2010-06-29 17:57:13

我剛剛創建使用XCode添加了一個新文件，將其稱爲GANTracker_Stub.m。刪除了GANTracker_Stub.h文件並將上面的代碼複製到其中。然後當你編譯你的項目時，GANTracker_Stub.m會自動覆蓋靜態庫中的GANTracker實現。那有意義嗎？ – 2010-06-30 10:47:20
