<object> height in ios

hello i have an ionic V1 app and i used Object to show my website content and everything works find on android but it gets stuck on ios unless i specify the object height in(px) but the content height is dynamically changing so if i give less height some content wont show and if i give more height there will be space after footer

so is there any solution to my problem thank you

<ion-view  view-title="<img src='img/ionic2.png' style='width:70px;margin:7px auto;display:block;position:absolute;left:50% !important;'/>">
  <ion-content id="con15" style="overflow:scroll; position:absolute; -webkit-overflow-scrolling: touch; width:100%;height:100%;">
    <object id="iframe15" onload="document.getElementById('con15').scrollTop = 0;"  data="https://www.knnc.net/archive.aspx?smartphone=yes"  style="width:100%;border:none;height:100%;padding-top:40px;"></object>
