Wechat H5 page uses html2canvas to draw pictures, long-press menu only [save image], not [send to friends] and [identify QR code]

the Wechat activity page we made
needs to be finally drawn as a picture with a QR code
and finally prompts to share it with friends

.

A picture drawn by html2canvas
then canvas is transferred to base64 as the src of img

ios end length Press img only pops up [Save Image] and [cancel]

there is a problem only on the ios side, but it occasionally pops up [send to a friend]
there is no problem on the Android side

I don"t know if anyone has ever met
looking for answers

I guess yours is a canvas tag


? How did the landlord solve it? Is it because base64ios can't share?
