ios无痕浏览器不识别localStorage并报错的解决办法：

 try 
              localStorage.setItem('isPrivateMode', '1');
              localStorage.removeItem('isPrivateMode');
              window.isPrivateMode = false;
             catch(e) 
              window.isPrivateMode = true;
            
            if (!window.isPrivateMode && window.localStorage) 
              localStorage.removeItem('namegtcrem');
              localStorage.setItem('namegtcrem',username);
              localStorage.removeItem('passwordgtcrem');
              localStorage.setItem('passwordgtcrem',password);
            
            else 
              try 

                var cookies = function();
                cookies.prototype = 
                  setCookie:function(c_name, value, expiredays)
                    var exdate=new Date();
                    exdate.setDate(exdate.getDate() + expiredays);
                    document.cookie=c_name+ "=" + escape(value) + ((expiredays==null) ? "" : ";expires="+exdate.toGMTString());
                  ,
                  getCookie:function(name)
                    var arr,reg=new RegExp("(^| )"+name+"=([^;]*)(;|$)");

                    if(arr=document.cookie.match(reg))
                      return (arr[2]);
                    
                    else
                      return null;
                    

                  ,
                  delCookie:function(name)
                    var cookie = new cookies();
                    var exp = new Date();
                    exp.setTime(exp.getTime() - 1);
                    var cval=cookie.getCookie(name);
                    if(cval!=null)
                      document.cookie= name + "="+cval+";expires="+exp.toGMTString();
                    
                  
                

                var cookie = new cookies();
                cookie.delCookie('namegtcrem');
                cookie.delCookie('passwordgtcrem');
                cookie.setCookie('namegtcrem', username, 30);
                cookie.setCookie('passwordgtcrem', password, 30);

              
              catch (e) 
                alert(e);
