i have prototype cell , set uivisualeffectview
within contentview
. visual effect view's blur style dark , vibrancy off. set alpha of visual effect view 0,5 using ib.
then on runtime, warning says:
<uivisualeffectview ...> beingness asked animate opacity. cause effect appear broken until opacity returns 1.
i couldn't understand why warning there , how can set alpha property properly.
as far can remember cannot alter alpha of visual effect view. alpha has one.
