I am Making an Iphone application which is web-service enabled. Also I have skeleton of this application.I am using rest to feed the contents of view controllers. When application is launched it is presented with Login page asking username and password. Clicking Login button sends request to server and in response xml data is fetched. Then I parse this data to get user logged. But i dont know how will i manage sessions,and how clicking logout button will end this session. This application is most-like RSSFeeder,means user gets real-time data.
Any help would be greatly appreciated.Thank You All.
As it seems obvious you are using REST connection,you need not take session in consideration.
just feed your username and password and other stuff in the URLRequest and make connections.
You can also use Setting perferences in settings.Bundle to autofeed your URLRequest.

I am working on my first app so I am not so experienced with this stuff yet. I have figured out how to send a POST request url to a php page and process the php to register a new user in the mySQL database or log in to the app by connecting to the database to see if the user exists.
First off, does that seem correct? To just send the request to register a user with text field variables and to log in by checking if the text field information exists in the database or should I be implementing some other ways to do this?
Second, What should I be doing once the user enters in his credentials in order to tell the app that the user is logged in so that if the app closes down and the user goes back to the app, it will automatically log the user back in.
That being said, the way this app is going to work (as of now) is the user will log into the app, and the log in view will go to a different view but then the user can log out and it will go back to the log in view. Once I can tell the app that the user is logged in, I should be able to tell the app that the user isn't logged in anymore.
How you implement your database security is up to you. I would recommend you route your authorization/updates/gets/posts to an API so you don't need a PHP "middle man" (unless the PHP is your API) and you can send requests directly to the API layer and handle the rest on the server.
As for the plain text part, it is a common security practice to encrypt passwords on the database. On the client side, I'd suggest using the Apple Keychain to store the username/password for future use. In iOS, this can be easily implemented using this Keychain Wrapper if you're using ARC or this one if you aren't.
Question:
I am actively looking in the source code on Github's facebook-ios-sdk project myself but I was wondering if anyone already knows how to relaunch an app that sent an iPhone user to Safari, such that the user can come back after some work has been finished?
Example:
When using facebook to login, the original app is relaunched after the facebook login page has authenticated the user.
Motivation:
I would like to be able to do the same for youtube videos without having to completely lose the user. I don't want to use the standard webview approach because I don't want to provide extra space to first let the video load for the user and then have the user click the play button. I want to skip the play button and its associated click entirely! Instead I want the user to be able to click on just an everyday regular iPhone button and be shown the video with the navigation for coming back to the app via relaunch.
You need your app to register a "custom URL scheme". Then get the callback in the remote web service to return a URL with that scheme. iOS will then launch your application.
More (somewhat old) info available here.
A list of common custom URL schems on iOS can be found here.
Generally, as part of the OAuth login process, you supply a callback URL as one of the paramaters. What this does, is tell the remote server (YouTube), that on successful authentication, redirect the user to the supplied URL. If YouTube supports this (does it support OAuth?) then on successful user login within safari, youtube will tell users safari to redirect to the supplied url. If this url is a "custom URL scheme" it will cause your app to relaunch and you can handle the situation from there.
I've done all the necessary pages etc for my app now. It uses JSON parsers to retrieve information.
I'm now stuck on the login of the app as users will need to login to use the app. How do I need to approach this and are there any tutorials that demonstrates a simple login and pushes into the main app?
Thanks.
ASIHttpRequest might be very useful for you.
I didn't do it myself, but I think you could use Web View at start to retrieve login, password and then send it to your server to verify. You do it the same way as in usual browser. Or you can use usual view and then send info to server using GET-POST methods of HTTP.
I'm building an iPhone app that, in part, allows the user to log in to, pull data, and post data back to a Wordpress site (more specifically, Buddypress). One way I'm considering approaching this problem is to use a series of UIWebViews to display the mobile-themed version of the site.
Ideally, I want the user to be able to, upon first-launch of the app, input their username and password, and then never have to do it again (functionally similar to tons of other social apps out there, like Facebook, Twitter, etc.)
Here's my question - obviously it is easy to store the user's login credentials, but how do I, in the background, establish an authenticated and persistant session with those credentials each time the app opens, so for the user, they are never presented with a login screen again, and can just use the app like normal?
Does anybody have any suggestions?
WordPress uses XMLRPC to authenticate. You can, on top of the API given, write your own codes to store credentials. Persistent session can then be made.

I'm building an app that checks as site every 15 minutes for changes. I can do this fine in the app, when it's open. But how do I go about doing this while the app is in the background?
The trouble is I don't think I can use the Push Notification Service. The page on the site which is being checked, requires the user to be logged into the site. Because there is a cookie jar for each app, the user logs into the site through a UIWebView at the beginning and then once logged in, the site is polled every 15 minutes using NSURLConnection and receives the data for the logged in user because of the cookies created at login in the webview. I don't believe there is a way to do this on a server for many different users? And if there was wouldn't the user's site username and password have to be stored on my push server which is a huge no.
So can I use task completion, or is it possible to access a page that only appears correct when the correct cookies are present from a server and then use push notification.
Unfortunately there is no way to get the cookie from a UIWebview. And task background completion can only run for 10 minutes.
I'm not sure what kind of website you are trying to access, but if you can replicate the login using a NSURLConnection you can retrieve the cookie using NSHTTPCookie. Then store the cookie data on your server and then access the web site from the server with the "Set-Cookie" header to check the content for changes.
This, of course, depends on how long the cookie lasts (expires).
