**跳到问题/解决方案的底部**
我刚刚将我的应用从GA 2.0转换为3.0。其中一部分转换包括整合GAIDictionaryBuilder。应用程序正在运行，但很快在启动后就会崩溃。以下是从开始到崩溃的xcode日志。底部有更多注释。

我理解这个崩溃是因为某个地方使用了未被识别的选择器与GAIDictionaryBuilder一起，但是它发生在哪里？我在很多地方都使用了GAIDictionaryBuilder，并且使用方式总是相同的。有没有建议我下一步该怎么排除故障？
问题
[[[GAI sharedInstance] defaultTracker] send:[GAIDictionaryBuilder createEventWithCategory:@"General"
action:@"App Became Active"
label:nil
value:0]];
解决方案
我需要将build添加到GAIDictionaryBuilder中。
[[[GAI sharedInstance] defaultTracker] send:[[GAIDictionaryBuilder createEventWithCategory:@"General"
action:@"App Became Active"
label:nil
value:0] build]];
