Question

我是iOS开发的新手，我的iOS应用程序崩溃了（由供应商开发）。我学会了阅读日志，这就是我所看到的：

2015-06-15 19:00:51.628 my_app[2540:113596] WARNING: GoogleAnalytics 3.12 void GAIUncaughtExceptionHandler(NSException *) (GAIUncaughtExceptionHandler.m:48): Uncaught exception: *** -[__NSArrayI objectAtIndex:]: index 0 beyond bounds for empty array
2015-06-15 19:00:51.636 my_app[2540:113791] INFO: GoogleAnalytics 3.12 -[GAIAnalyticsPropertiesStore propertyRecordForTrackingId:] (GAIAnalyticsPropertiesStore.m:464): Record for tracking id my_tracking_id not found
2015-06-15 19:00:51.640 my_app[2540:113791] VERBOSE: GoogleAnalytics 3.12 -[GAIBatchingDispatcher persist:]

我想知道Google Analytics是否导致崩溃或其他导致崩溃的事件。 API调用很好，应用程序的其他部分工作正常。

修改 Additonal stacktrace

Answer 1

刚遇到类似问题，并得出结论认为不 Google Analytics导致崩溃。谷歌分析仅仅是为了报告目的而绕过另一次崩溃。

如果您在App Delegate的didFinishLaunchingWithOptions:（或其他位置）中更改了以下设置，则崩溃将在XCode控制台中显示为正常错误：

GAI *gai = [GAI sharedInstance]; gai.trackUncaughtExceptions = NO;

Answer 2

调试此问题的一种方法是在objectAtIndex上添加一个符号断点：这可能会导致对objectAtIndex的多次命中：在调试器遇到你之后的那个但是它保证找到它之前。

Xcode 4中的步骤：

View > Navigators > Breakpoint Navigator
click '+' and choose Add Symbolic Breakpoint in the pop-up
type in "objectAtIndex:" in the Symbol text field and click Done

在运行时，如果你不能告诉你正在点击哪个objectAtIndex，请将Debug Navigator底部的滑块一直移到右边。
