Iphone localStorage “QUOTA_EXCEEDED_ERR” issue

Question

I trying to use Client Side Storage available in HTML5 (localStorage) for Iphone Application , and I\'m completely aware of the \"QUOTA\" associated for loc

Answer 1

I had the same issue and JoeCortopassi is only partly right: it is caused by private browsing being enabled. The code provided in that answer does not help much though. When I tested on iPad Safari(ios5) I got

console.log(!!window.localStorage); // true

As soon as I try to set a value, I get an exception:

localStorage.setItem("test", "test") // Exception 22 is thrown

So to accurately test for local storage support, it is necessary to try and set a value in local storage, for example:

var localStorageSupported = function() {
  try {
    localStorage.setItem("test", "test");
    localStorage.removeItem("test");
    return true;
  } catch(e){
    return false;
  }
}
