problem description
 when vue-router switches routes under iphone5 ios8, the dom nodes of the previous page still exist 
, but it is ok 
 destroyed methods are all executed 
 I"m not sure how this problem arises. 
second addition:
 dom destroyed
demo
  
 
 just like above-there are two routing components under sharpapp. If I jump to the next route at this time, the dom of the current page will not disappear, it will appear with the dom in the next routing component
