How to create an USSD Mobile Application - ussd

I want to create a mobile app that can communicate with USSD. We have lot of services we buy using USSD code, I was thinking about building an app to help solve that problem. An app that use to download and use to do their transactions. For example if someone want to buy something using Mobile Money they would use the USSD code which is *144#. If there is a way to create an app that will be able to do the transaction that will be great.
I am thinking of building this app using NativeScript. If there is any other framework that would make me easier I would really appreciate it.

My team and I developed a platform called AutoUssd which allows u to do this. Kindly check it out at https://autoussd.com to see if it fits your needs...

Entering website pushes notification on iPhone

I want to make a Simple App. I’m a beginner in Swift, with Just basic knowledge, But I’m Very Good at PHP and JS, So basically, programming is not foreign to me.
The App should cowork with my website and it should do Only one thing. When person visits my web, I get a notification on my iPhone. Simple as that, yet I have no idea how to make it.
Any ideas, recommendations?
Any help Appreciated.
Thanks.
Dave
I think the easiest way will be to use OneSignal service for Push Notifications. When somebody enters your site, you call method on OneSignal API via your PHP code. And it sends push to your app.
OneSignal API is here:
https://documentation.onesignal.com/docs/onesignal-api
Documentation about iOS integration is here:
https://documentation.onesignal.com/docs/ios-sdk-setup
It is free and easy to use.
That would require a bit of PHP and SQL (and everything similar). You can check out Google Analytics.

Iphone App that can open other apps? How

There is an App out there that can 'intercept' pictures from snapchat. I'm not sure what low level witch craft they are using to accomplish this, but I want to learn more about how to do it and I don't know what to search!
Can someone please help me? This is the app I am referring to:
https://itunes.apple.com/us/app/snapbox-save-snapchat-snaps/id727651340?mt=8
I just read the app description you are referring, and I don't think intercept could be the right word to use. You will need to read more about Terms of Service from SnapShat and probably try to read if they provide any official api so you can use it.
What this app does, is actually consuming in someway the posts you are receiving and then saving it to your iPhone. That's not a hard task tough.
In this case, you're providing your snapchat login to this app and they're using it to pretend they're you to communicate with Snapchat.
No actual "intercepting" is happening, and the app likely works without Snapchat installed.

Is there any sandbox environment for Twitter app development?

I am developing an iOS application and I am integrating the ShareKit 2.0 project. I want to share content via Facebook and Twitter. Both of them require to create an application on their platform. Everything at this point is ok.
The problem is that as the application in under development, we don't want it to be visible by anybody that is not in this project, so we can't publish content on our facebook/twitter accounts visibly for external people.
Facebook supports a sandbox environment where the app admin can allow just certain users to use the application, so only those users will be able to access and view contents related with that app. And I am looking for something similar on Twitter, but I can't find it.
This is a very hard problem, when you don't find out if this is possible or not, because you never know when you should stop looking for the answer and decide it's not possible. So here I am, asking to SO gurus: is there any sandbox environment for Twitter so we can develop and test our applications?
Thank you very much!
Ok, as I received no answer for this question, I will finally deduce that there does not exist such a sandbox environment for Twitter.
However, I "solved" my requirements by setting my testing account in private mode (I didn't know about this because I rarely use Twitter). Right now this will do the trick, but of course it's much worse than the Facebook sandbox environment.
Apparently not:

There are unfortunately no sandboxes for this kind of activity. It's best for automated testing to not actually hit the API but instead to mock it out.
I recommend you just create a dummy account for testing. I don't know any other way.
Have you tried http://twitsandbox.com
twitSandbox is a web application to support creating applications using the Twitter APIs. It actually processes the methods of almost all and you can confirm what kind of response receives.

Send an invitation to a list same app

I am pretty new with iOS 5 and I am thinking in writing an app.
I would have a list of people inside the app who has it. Then I would invite them to an event.
I don't need any code right now I just wanted to know the concept behind this.
First, how an app can recognise who has my it installed, so it can show a list of people.
Second, after creating an event with a group of people how can I send an invitation to them.
Thanks
From a very general standpoint, what you need is a back-end server to interact with your app and store user/event info. You can either build your own or try to use a service like Parse.

rails 3 and phone apps

Hoping someone can help me out. If I'm developing a Rails 3 app, but later would like have a mobile version later down the line, whether is iphone/bberry or anything else. Does this mean that the mobile apps will be developed from scratch or will they utilize the existing infrastructure somehow?
Does anyone have experience with this?
Thank you!
It depends on what type of mobile app you're talking about. You can create either:
A phone friendly version of your web app
A native app on the platform of your choice (iphone, bberry, etc)
If you go with #1 all you need to do is create phone friendly versions of your views. But your users will need to use the web browser on their phone to view your site. An example of this is www.engadget.com versus m.engadget.com. The latter is just the engadget website optimized for viewing on your phone.
If you go with #2, at the very least you'll need to create a native client app on the platform you select. However, if you design things right you can leverage much of the functionality that's already in your website.
Take twitter as an example. You can use the twitter website to use features of twitter or you can use a native iphone app like twitterific. The iphone app (probably) uses some twitter API to access functionality that's the same as when you use their website.
You will just need new views for mobile version.
You will need to probably output the data in the form of json or xmls if it is a native app so you will need to modify your active controllers. If it is web app or web page then you will need to modify your views to make them mobile browser friendly.
