How can I use html with ajax call in cordova in ios build?

Question

$.ajax({
    beforeSend: function(xhr) {
          xhr.setRequestHeader(
            "Authorization",
            "Basic " + btoa("test" + ":" + "test@password")
          );
        },
    url : pathUrl+"login",
    type : 'POST',
    data : {
        'email' : email,
        'password' : password
    },
    success : function(responses) {
        response = JSON.parse(responses);
        if(response.success == true) {
            localStorage.setItem('user', response.user_.id);
            localStorage.setItem('loginEmail', response.user_.email);
            window.location.href = 'home.html';
            localStorage.setItem("ID", "uni_id");
        }
        else {
            alert(response.message);
        }

    }
});

It's working fine in android device but its not working in ios device. It's retunes xmlhttprequest cannot load due to access control checks.
