Push does not work on ios

Hello, can you tell me that my code is the error?

I would like clarified that the push works for android, ios but it does not work. In my panel 'acs titanium' the device will not know to register (ios)

Ti.include('common/globals.js');
 
var osname = Ti.Platform.osname;
 
var Cloud = require('ti.cloud');
if (osname == 'android') {
    var CloudPush = require('ti.cloudpush');
}
var deviceToken;
 
//user login on cloud using default credential
function loginUser() {
    Cloud.Users.login({
        login : 'MyLogin',
        password : 'MyPassword'
    }, function(e) {
        if (e.success) {
            var user = e.users[0];
            Ti.API.info("Loggin successfully");
            if (osname == 'android') {
                defaultSubscribe();
            } else {
                getDeviceToken();
            }
        } else {
            Ti.API.info("~~> Error :" + e.message);
        }
    });
}
 
// getting device token
