ios - Do iAd impressions count when UIViews are above the iAd in the subview hierarchy but beneath the iAd at render time? -

so in lazy effort maintain iad ontop of app @ times iad visible added quick code vc right after adding adview subview:

adview.layer.zposition = 9223372036854775807;

so question is, add together subview vc.view , technically infront of iad view (adview) far subview hierarchy concerned...

but @ render time, adview appear on top due cg , zposition...

so impression still count?

does apple monitor subview hierarchy observe if view covering iad view? or check @ render time if it's ontop or not?
