objective c - how fetch the data at same time when i register the all information on webserver in iphone -

I have a xib and that is xib I have a username, password, and a button login

And in the tabbar I have a tab bar which is a name registration if I go to the server on the registration tab, then I have given the server path bet because all the form URLs, usernames, passwords, first names and last names are taken as such. On the registration form

And now if the user submits this form on the server then I have to show the pop message, which show that now should be registered after the login page. The data created by that user in the user's name and password

All of these fetches should be within the same time as the user submits the registration form, after which the login page works But one condition is that if the network is available then the user name and password should be identical with the same username and p, if there is no network, either on the web server or not, then user login for user login And passwords, using the SQL database in the iPhone, it should match the database table from the local

Please help me find a friend of this How can I do this on a single regitration and bring data with json and save it in the local database? "post-text" itemprop = "text">
