Is there a way for users to invite their friends via LinkedIn using iPhone sdk? - iphone

I am done with login using linkedIn but I did a lot of goggling and did not find a way to invite friends via LinkedIn. If Somebody have done this then please give me a guidance or tutorial to get rid of this.
Any help will be appreciated..
Thanks in advance

Once logged in, you should be able to invite people as friends using LinkedIn's own API. Check out the documentation here. This will involve POSTing XML to the API as described on that page.
Note that there are some "usage guidelines" you'll need to follow, too (The user must be given a choice about whether to send the invitation, etc...)

Facebook - refer a friend

I'd like to enquire with the Facebook heads on here about how best to do the following:
I'd like to run a promotion from my Facebook business page that encourages users to recommend a friend in order to gain access to enter a competition. Obviously being in the Facebook environment it would be preferred to encourage Facebookers to refer friend's on their profile. Anybody know if there's an app out there (I've searched and not found) that does this? Does the Facebook API allow access to select specific friend(s) to notify on Facebook?
Thanks for your help & suggestions.
Yes, you need to have read_friendlists as an added permission to your facebook app.
From there I think you can do a FB.api() kind of call to get that information

I think the requests dialog does what you were looking for?

Can I use some API call to invite User's Friends?

I want to invite facebook friends to my app. via some sort of API call whether rest or PHP Sdk, so is there a way to do so. I know about multifriend selector in FBML but don't want that. Please tell that which API can be used to do so? Graph API or any other? I am using PHP so if you know some PHP API call then that is also good.
thanks in advance for assisting me.
You can use the Requests Dialog for invites. This will prompt the user for which friends to send a request/invite to. This is designed to work in iframe apps, no fbml required.

Anyone know of a good tutorial for Facebook authentication?

I'm linking my app to Facebook, and would like people to log in with their Facebook account, but I can't figure out how to do this. I had read up on Facebook Connect, but it seems that that's not used any more - but every tutorial I can find seems to refer to it. When I try to follow them, it doesn't work, because the interface has changed.
So, can anyone direct me to a tutorial or guide to doing this the new way?
Basically, what I want to do is this:
A user who is signed into Facebook and comes to my webpage is automatically logged in to my app (with the usual Facebook 'granting permission' windows etc), or can sign in with their Facebook account if they're not already logged in.
I then want to use Facebook to link users with their friends who are also registered on my site, so they can share things.
I would also like to have access to Facebook comments made on wall posts from my site - so the comment stream for a particular post can be seen on my site as well as on Facebook, and comments can be made on either.
If anyone can point me in the right direction (or even tell me what I should be typing in to Google!) I'd be very grateful.
Thanks.
Some sample apps that do many of the things you speak of are shown here. The Graph API is probably your best bet right now for delivering the content and access you need and there are numerous tutorials online for how to use it, including the Facebook Developers site itself.
You will find good Tuts on ThinkDiff, e.g.
http://thinkdiff.net/facebook/new-javascript-sdk-oauth-2-0-based-fbconnect-tutorial/
http://thinkdiff.net/facebook/php-sdk-3-0-graph-api-base-facebook-connect-tutorial/
http://thinkdiff.net/facebook/graph-api-iframe-base-facebook-application-development-php-sdk-3-0/
I know this is an older question, but the current method for authentication is OAuth 2.0.
Facebook provides a pretty good outline of what steps are necessary in this Reference:
https://developers.facebook.com/docs/authentication/client-side/
This example allows the authentication to occur entirely in Javascript on the client side so that you can request a potential user to authenticate via Facebook and then confirm access to your application.
If the user is already logged in, only the access confirmation for your application is performed.
If the user is already logged in and access has already been granted, the user is not required to login, or reconfirm access.

What can we do with facebook api in iphone application?

I want to use facebook api in my iphone application. I know that we can post to walls with facebook api but i have no idea about other features like :-
edit profile
send messages
add friends
get friends information etc.
So can anybody give me details about all the things we can or cannot do with facebook api ?
Here is a non-Facebook.com explanation of what the API can do:
http://en.wikipedia.org/wiki/Facebook_Platform
Check out the Facebook-ios-sdk.
The top level readme gives a good overview of the features.

Facebook - Refer a friend functionality

I need to create some functionality on a clients website which lists the users friends and allows them to send a link to their inbox.
So far, I have it listing the users friends using fb.api functionality, but from what I can see, there is no way to send the users friend a message (not post to their wall, this needs to go into their inbox.)
edit: The user would log in first.
Does anyone know if this is possible? I've tried looking at fb.ui but I can't seem to find anything useful.
I think this is (or should be) impossible. I wouldn't like it at all if a third party could send me messages because one of my friends allowed it. I guess that would be my last day on Facebook.
I would suggest you look into the fbml fb:request-form doc's. It looks to me like this is what MGM is using. This allows a user to invite friends, and I think it's as close as you can get to what you are truly after.
