How would I be able to have a user enter a stock ticker and using real time data, display the current stock price for that ticker on an iPhone app?
Check out the free Yahoo! finance CSV api:

this question:
How to download CSV file from server in Objective-C
and this little tool:

You could grab current stock prices for lots of stocks in one api request and deliver them to your app by parsing the csv.

A few months ago, the complete pricing matrix could be downloaded in CSV from the App Store Connect with the list of all countries and tiers from this URL:
https://appstoreconnect.apple.com/WebObjects/iTunesConnect.woa/ra/ng/app/[APP_ID]/pricingMatrix
But unfortunately this URL stopped working and has been changed to this one:
https://appstoreconnect.apple.com/apps/pricingmatrix
With no CSV export button. Any idea?
I am trying to track traffic coming from Apple News through Google Analytics, submit in RSS format. After online search I found that only if it's submitted in Apple New format. And that RSS feed is unreliable to track with GA.
Is there any other way to do this?
The first link you provided shows that the browser dimension is set as AppleNews for those visitors (I've never used Apple News before, but I'm guessing it's an in-app browser).
This gives you a few options:
Use a secondary dimension of Browser with an advanced search for AppleNews in your Acquisition report.
Create a segment where the Browser matches AppleNews to make it available for all reports.
Create a find/replace filter when the Browser matches AppleNews to change the acquisition data itself (source/medium). You'll want to be careful with his because it permanently alters your data!
The other thought I had is that maybe it's possible to use UTM query strings only when submitting to RSS? If the data is scraping your website you could programmatically update the RSS URL to include UTM parameters to track the source/medium that way (this may have varying success because of other scrapers outside of Apple News).
If you manually submit to Apple News, you could manually UTM tag your URLs so the source/medium is forced to Apple News.
I'm new on iOS development and I got a problem with storing the last time Tweets got updated from API in iOS?
I want to retrieve tweets after the last time I retrieved and what is the best practice for getting the time my app retrieving tweets? Store it somewhere or get the latest tweets from core data(I store tweets in core data)?
You can use the since and until operator.

I'm trying to design an app for my club at school. What I want to happen is when there is new information about meetings or events I want to be able to add this new content to the app and then have it visible by other app users.
So my question is how would I approach this idea?
Conceptually, you're going to need to have a centralized server which contains the data, an API to connect an application to this data, and finally the end user application.
On the server end, you could have a simple database which will house the event and meeting information.
On the API end, you could have a simple script which fetches the latest entries in the database and displays the data in a standard format such as JSON or XML.
On the app end, every time the user opens the application, fetch the latest data from your API and parse it into an array. Then, just populate a table or collection with the data in that array. You could also add a pull to refresh control to fetch the latest information at any time so the user doesn't have to launch the app again.
I was wondering whether it is possible to monitor how many people are downloading my Blackberry app from the online store. Is there a developer/admin login to access this kind of data? I have a login for the vendor portal on BlackBerry App World but I dont see any such option there. Can anyone please help with regards to this topic?
I have tried the following:
In my vendor account, there is an option for "Download Reports" with which I have generated a chart report of the "Total Downloads" between specific dates. I am looking for a more detailed statistical version (Excel) as the chart is not as clear.
I managed to get the exact report required. In order to generate a statistical report of the number of downloads of a BlackBerry App from the online store, we can log in to our account (vendor account) and go to "Manage Reports". In it there is an option for "Schedule Reports". Inside "Schedule Reports", select the application for which you need the count of downloads and select a start date and end date. The report can be sorted by:
Date only
Product, then Date
Carrier, then Date
Country, then Date
Device, then Date
The report is detailed and can easily be downloaded both from "Manage Reports" as well as "Download Reports". The .csv file can be viewed in excel and can later be saved in .xls format as well.
