ios - Can we measure the data of M7/M8 while the iPhone is unawakened in the CLVisit delegate method? -

can write code in method m7's data , useful while don't run app?

-(void)locationmanager:(cllocationmanager *)manager didvisit:(clvisit*)visit {  } 

yes, can query cmmotionactivitymanager locationmanager:didvisit:

please note visits not reported app in real time, in tests delayed 20 60 minutes. means starting activity monitoring startactivityupdatestoqueue:withhandler: makes no sense, these updates won't tell happened during visit.

however still can fetch , analyze activity events happened during visit using queryactivitystartingfromdate:todate:toqueue:withhandler:

keep in mind locationmanager:didvisit: might , called while app in background mode, have 10 seconds query cmmotionactivitymanager , process data. since have no control on cmmotionactivitymanager , there no guarantee process query in timely fashion, may want invoke beginbackgroundtaskwithexpirationhandler: in locationmanager:didvisit: well.
