iphone app userid - iphone

I have an app where we want users to be able to send us email/info. This would be a standard template which will open up on a button click within the app.
I am struggling at the moment to find a legit way to do it. The problem is there are 2 things I need.
1) A way to let users send email to me
2) A way of knowing the person sending me mail is actually someone who has downloaded my app.
Does anyone know if there is a way to do this? Does apple give us information/user id's or email id's of poeple who have downloaded the app?
Many thanks in advance for any help with this..

Here's a good example on how to send email.
As for identifying if they send it from your app, you might have to create some login feature on your own. I haven't heard of Apple providing IDs of users who have bought your app.

How to let one user send a request to another user only if they both have the app?

I want to have one user send a request to play the app with another user but only if the other user also has the app. I have seen this done in snapchat it lets you add (or friend) people who also have snapchat. I figure the user has to grant permission for the app to access contacts but after that I am pretty lost. Does anyone have any links that discuss this?
Thanks
Many apps ask for an email to log in or they ask for a mobile number and then find friends using the contact book with that data.
You request access to their contacts and upload them to your server. Make sure you are clear about what is happening. Path did this without clear disclosure and people got worried.
There is no way to programmatically grab an iPhone's phone number so you have to ask for it.
TLDR:
Ask for email or mobile number
Ask for permission to contacts
Match those on your server and return results.
You could also theoretically use Facebook, but I don't have any experience with that API.

SMS notification when selected friends are online

I have an idea to develop a Facebook app which notifies the user through SMS when his/her friends come online. The user can pre-select the friends he/she wanted to get SMS notifications of.
This is my first attempt at developing for Facebook so I have zero experience and knowledge about the platform. I just want to know if my idea for such an app is possible? Does Facebook have an API for SMSes? Or do they let 3rd party messaging APIs (such as this one I came across) to work with them.
Thank you.
A Facebook app is actually ran off of your server and you can do anything that you want as long as you stay inside the limits of what you requested as far as information the app needs. As far and getting the information it is relatively easy. I made a extremely complicated app in 3 days. Once you read and get how to pull certain information, the rest is cake walk

How do I import facebook friends from the another website

I am looking for a way to connect to facebook by allowing the user to enter in their username and password and have our app connect to their account and get their contacts so that they can invite them to join their group on our site. I have written a facebook app before, but this is not an app as much as it is a connector so that they can invite all their friends or just some to the site we are working on.
I have seen several other sites do this and also connect to Yahoo, Gmail and Hotmail contacts. I dont think they are using Facebook Connect to do this since it is so new, but they may be.
Any solution in any language is fine as I can port whatever example to use C#. I cannot find anything specifically on Google or Facebook to address this specific problem. Any help is appreciated.
I saw a first answer get removed that had suggested i might need to scrape the friends page. The more I look around, this might be what i need to do. Any other way i think will require the person to add it as an app. I am wondering how a answer can get removed, maybe that user deleted it.
Try This
Not sure if its possible explicitly but there are indirect ways to do it!!!
Here is another article that seems to cover what you want to do http://facebook-developer.net/2008/02/20/allow-your-users-to-invite-their-friends/

How can I use the facebook connect api for the iphone to to invite friends to an application or send a message

In my iPhone application, I wanted to add the function of signing into Facebook and letting a friend know about the app. I know how to sign in and get the friends list, but I cannot find a good way of inviting a friend. So far, I haven't been able to come up with a way to invite a friend (I don't think one can with the iphone facebook sdk yet) or send a message to the inbox. Is there a way to do either of these? If not are there any better options I haven't thought of? Thank you for any advice.
