localStorage不再适用于iOS 7 WebView

请从要点尝试此cookie策略设置: https://gist.github.com/steveriggins/6652508

[[NSHTTPCookieStorage sharedHTTPCookieStorage] setCookieAcceptPolicy:NSHTTPCookieAcceptPolicyAlways];

由于升级到iOS7,当网页重新加载时,存储在localStorage中的所有内容似乎都会被擦除。

<script>
function supports_html5_storage() {
  try {
return 'localStorage' in window && window['localStorage'] !== null;
  } catch (e) {
    return false;
  }
}
if(supports_html5_storage()){
 rString=localStorage.getItem("SerialID");
 alert("We have localStorage support "+rString);
 if(rString) if(rString.length>0) alert("SerialID is present");
} else {
 alert("We do not have localStorage support");
}
</script>
