GAIDictionaryBuilder set forKey:GAISessionControl error reads:value for key的值表示它不符合代碼。Google Analytics API v3未知錯誤。 createEventWithCategory:not compiling
GAIDictionaryBuilder *dictionary = [GAIDictionaryBuilder createEventWithCategory:@"UX" action:@"App started" label:nil value:nil];
[dictionary setValue:@"start" forKey:kGAISessionControl];
[[GAI sharedInstance].defaultTracker send:dictionary.build];
我直接從他們的網站谷歌之後的文檔,&仍然不知道那裏的錯誤是哪裏來的? https://developers.google.com/analytics/devguides/collection/ios/v3/migration#setting-data
