Exist any Obj-c library to integration with paypal? - objective-c

I wonder if exist a pre-made objective-c library to work with paypal, including with credit-cards.
My google search not get returns (I look for objective-c paypal)
Also, if exist other librarys for common gateways....

If you want it to go through your application, however, you could use WebKit to integrate a web view that connects to PayPal. That way, everything can be contained within the application but you would still work with PayPal the way they want you to work with them.

PayPal code for iOS, get it from x.com

I don't think so, because they want you to go to their site. If you could just supply the data through a framework users couldn't trust Paypal.

Missing operations in gooddata java SDK?

I'm trying to confirm all the calls we currently make are supported in Gooddata's java sdk (https://github.com/gooddata/gooddata-java/) before we decide whether to update to use this.
I have confirmed all cases except 2 and am hoping that someone might be able to suggest how I might make these calls in the java SDK today.
list all users in a domain: (https://help.gooddata.com/display/API/API+Reference#/reference/users/manage-users-in-a-domain/list-all-users-in-a-domain)
assign a userfilter to a user (https://help.gooddata.com/display/API/API+Reference#/reference/data-and-object-permissions/assign-a-data-permission-to-a-user/assign-a-data-permission-to-a-user)
I just want to confirm these operations are not currently supported before I investigate effort to add them.
As far as I know, you are right and there is no built in support for GoodData domain (also called organisation) user handling (yet). On the other hand using "com.gooddata.sdk.service.httpcomponents" you can easily work with any GoodData API within your code.
In case you wouldn't be tied to strictly to Java - there is possibility to use bit more robust "Ruby SDK" - https://sdk.gooddata.com/gooddata-ruby-doc/docs/getting_started.html which natively contains user management
Another possibility is to shoot feature request directly into the repository (https://github.com/gooddata/gooddata-java/issues) - we will check that up and most likely add the support soon (or at least give you the estimate).

How to fetch POP3/SMTP email using Cordova

I'm new to mobile development and have been looking for a way to retrieve basic email information from simple POP3/SMTP email servers.
I've seen many posts on how to send email using numerous Cordova plugins, etc., but I'm simply trying to retrieve email information for various listing and analysis purposes.
Is this even possible?
Thanks for the help and suggestions on where to start.
Cordova does not have built-in functionality for POP3/SMTP access. As inside your codova app you are running in the javascript/webview sandbox, you don't have socket access, so you can't implement this kind of functionality there.
This leaves you no choice but to implement a Cordova Plugin. You are in Objective-C land now, but unfortunately there aren't any convenient classes in the standard framework for accessing POP3/SMTP. Your best bet is using a library like MailCore.
Details on how to implement a Cordova Plugin (as well as passing the relevant email data from and to your javascript layer) are outside the scope of a simple StackOverflow answer, but the process is (fortunately) well documented.

Best way to implement a multi-user goal list?

I want to make a list of goals for my family and I that we are all going to follow.
I generally know how I'll implement the list part. Just a todo-list-esque app where you only cross or uncross things off on it. I haven't decided with what I'll implement that part, mostly because I'm not sure how the multi-user part will go.
I figured each person can log in with Facebook or Twitter, and based on your login you'd be able to see what you've checked off.
I've never built a login before, or built based off of a logged in user.
Which web frameworks would be best for this? How would you implement this?
Since you said you know Javascript well, it sounds like you're best bet is to just use Node.js and a simple web framework like Express.js.
This will allow you to write you server-side code in Javascript, which should make the process simpler for you.
For handling authentication / etc., if you're looking for a stupid-simple authentication library you can use express-stormpath -- it supports social login as well as username/password stuff.
If you're looking for a smaller solution, you can use something like passport.js and use the third-party plugins for social login.

Twitter API - which Library?

I'm new to objective-c/cocoa and I want to build a simple app using Twitter API.
I only want to access the Followers of the user and because of that I don't think I will need a complex library like MGTwitterEngine.
Is there any Engine out there to my needs or should I use MGTwitterEngine?
I'd recommend getting some experience with MGTwitterEngine. Even if you don't have a use for the entire library, I'm sure you'll want to take advantage of it later on down the road once you see what it's capable of. You can even find an entire tutorial from start to finish on creating a twitter client with the MGTwitterEngine.

TurboGears for ecommerce

Is there a good Open Source shopping cart implementation for TurboGears? (I found Satchmo for Django, but I'm coming up empty handed for TurboGears.) I'd like to avoid reimplementing this particular set of wheels.
No, I do not believe there is.
You might want to take a look at stroller it's a library to add ecommerce features inside turbogears2 apps. It supports both manual payments handling, dispatching and paypal payments. It is meant to be used without forcing users registration.
It is still in playground status and is missing documentation, but should be quite easy to mount it inside your app and start playing with it.
