[super load];
[self aspect_hookSelector:#selector(viewWillAppear:) withOptions:0 usingBlock:^(id<AspectInfo> info, BOOL animated) {
HDFAppLog(#"**************==");
NSString *currentPageName = [[info instance] hdf_className]; //页面名称，如:HDFSearchHospitalViewController
//FireBaseAnalytics
[FIRAnalytics logEventWithName:"page" parameters:{
"pageName":currentPageName
}];
//GoogleAnalystics
id<GAITracker> tracker = [GAI sharedInstance].defaultTracker; //调用默认跟踪器
[tracker set:kGAIScreenName value:currentPageName];
[tracker send:[[GAIDictionaryBuilder createScreenView]build]];

Answer 1

There is either no network connection or your network condition is flaky that it could not send data to the server. If there is no network, it will not schedule upload task. Sometimes, depending on where you are from, the network traffic might be filtered so it also fail to upload data. I think this is normal behavior.
