IOS embedded Vue H5 page routing returns problems that cannot be obtained

the problem is that I H5 has two pages, parent page A, child page B, A has a route to B, because put in the APP, the head is to be removed, so B does not have the above head, does not do the right arrow to return to A, the App side should be able to listen to the route directly, but my B route cannot be monitored on the IOS, and the Android end can monitor it. Have you encountered this situation?

if An and B are both pages in the route, they can be monitored.
on page A:

beforeRouteEnter(from,to,next){
    if(from.path=="B"){
        alert("B")
    }
    next()
}
