my team is currently in the feasibility phase of a 'usage meter app' iPhone app. We would like to read the phone's total count of
Sent SMS
Made calls
Data sent and received
We are not after the call history like other posts or like this blog post reading the actual call logs (http://iosstuff.wordpress.com/2011/08/19/accessing-iphone-call-history/). All we need is the stats and how they change over the course of time.
As of iOS 4.0, it's no longer possible to do that call history trick described in the blog entry you posted there. Apple took away that "artefact of the implementation".
If you are a registered developer and have access to Apple's "private" dev forums (at https://devforums.apple.com), do a search on "call history" over the past year or two and you'll see Apple engineering attesting to that fact in the first few threads you'll find.
You'll probably want to file an enhancement request at http://bugreporter.apple.com, but I wouldn't expect a positive outcome immediately as this probably raises security and privacy issues.
As for network statistics, you can get per-interface stats via "getifaddrs" (man page linked for you). You get the list of addresses on that system, and then for each AF_LINK address, cast the ifa_data field to a (const struct if_data *) and access the interface statistics from there.
(there are also two caveats -- these stats are all reset to zero at startup time, and there's no easy way to easily tell which interface is cellular versus WiFi).

As Sendgrid's documentation makes clear, their web GUI activity page is only searchable for the past 7 days.
How do I search for activity from farther in the past?
Web API documentation is here, but I can't find anything about just plain searching for info on sent emails. All I see are endpoints for seeing particular categories of emails' various fates, like blocks, bounces, invalid emails, and "filters", which seem like actions and not like filters.
It's got to be possible to just find info about some particular sent email, right?
It's not possible. As you noted, the documentation clearly states that:
Email activity only shows the most recent 7 days. To access data in
real time, we recommend that you consider implementing our Event
Webhook.
If you want to record all the history associated with your account you should record and save it yourself. You can record all the emails you send provided you have an endpoint to do so. See here: https://sendgrid.com/docs/User_Guide/Settings/parse.html
Later Edit:
"real time" means "as it happens", it does not mean "history searchable at any point in time".
When you use an API, as a developer, the responsibility to log all API calls and responses lies with you. While it's true that bounces aren't necessarily reported in the API call response, the SendGrid API offers several ways in which you can be notified. Personal opinion: I know this functionality is often omitted in the MVP because you need to go to market as soon as possible, but an ELK stack is not that hard to set up.
There are several ways you can look for bounces and other events as you can see here: https://sendgrid.com/docs/Classroom/Track/Bounces/bounce_reports_how_can_i_be_notified.html
Webhook for events: http://sendgrid.com/docs/API_Reference/Webhooks/event.html
Enabling Bounce Forwarding on your account
Bounce API: https://sendgrid.com/docs/API_Reference/Web_API_v3/bounces.html
If you really need to find out what happened on day X with email send Y, you can contact their Support team. They can probably look it up for you.
Personal opinion:
That 7 days is not a random number. I'm willing to bet that SendGrid does in fact log all calls you made but it can't provide them for an earlier time. When you use Facebook API, Twitter API, etc. You don't expect them to provide you with historical data of every API call you made. This is an ungodly amount of data. We're talking about an API that is used to send probably upwards of millions of emails per day, maybe even more. I believe they actually did the math and recalling historical data from earlier would put an unnecessary strain on the system, it would take a long time to answer such a request.
I'm sorry if I went on a bit of a rant but people often don't think about the volume of data needed to store such things and how much it would cost to search it.
I am currently developing an app for a company that is in a very competitive field. I have finished all of the features of the app that they requested except for one, making it somehow protected from their competing companies to download and use. I thought that I could set up a UIViewController with a password field that would check against some kind of database, but I'm not sure how to do the checking against a database part nor the practicality of it, and was hoping I could get some ideas on how to do this so that other companies couldn't steal and use this app without a password or something that changes like every 30 days or something and is kind of like an activation code.
Review the WWDC 2012 video "Building and Distributing Custom B2B Apps for iOS". I'm unsure if your app is in this B2B classification, it seems that it might be from your description.
What I ended up doing (if everyone needs a reference) was setting up a server with an SQL table that has pass codes in it. Since apple does not allow for any sort of system that requires you to "buy the app from outside the app store" I made a dumby username field (shame on me) that takes any value you like and then requires to have a pass code that fits. Once the pass code gets authenticated with the web server in a json sql request (there are plenty of api's to do this with) it comes back and sends the user to the first screen and sets a value in a plist with how many days of use the user has left. Whenever the user opens up the app it checks to see if the date is different from the last date logged in (saved in the same plist file) and if it is different then it calculates the difference and deducts that many. When the count reaches 0 it sends the user to the pass code authentication screen again. A bit complicated but an effective method of getting around Apple's restriction on not having a sort of pass code system like this. Thanks for the answers, unfortunately enterprise did not work for this company since they needed to be able to distribute the app to as many 3rd party members as they wanted to without having to worry about them leaving the company for other suppliers and remote management of the app (I.e ability to remote uninstall) was also not an option. Hope this helps someone someday!
I want to make an application on iPhone which locates the mobile number region(area) when the user gets a call. Can anybody give me guideline how to accomplish that task?
You can't access the details of an incoming call on the iPhone.
Crazy idea: User would define a phone number of your server (SIP, VOIP) as "forward when declined"-number. When the user gets a call, he would simply decline it, so it would be forwarded to your server. There you could extract the information and send it to the iPhone (Push Service). And finally you would redirect the call back from the server to the user's iPhone.
For anyone looking for an answer to the second part of this question (how to get the location for a number), there is a similar question (asked interestingly enough one day before this one) with several answers here:
Telephone area code to city name on iOS
I also discovered an SQLite database named calldata.db in the private framework AppSupport.framework that contains US cities, states and area codes, as well as prefixes (the three digits that come after the area code).
Using a query like this you could find out that area code 212 is New York, NY:
SELECT * FROM citycode, npanxx, npa
WHERE npanxx.npa = 212
AND citycode.code = npanxx.rate_center
AND npanxx.npa = npa.npa
I don't however know if accessing/packaging this database would violate any agreements with Apple (I do know that the Default.phoneformat file from AppSupport.framework has been packed with several apps which had no problems getting into the App Store, see comments here: https://stackoverflow.com/a/13116227/381233). Perhaps there are some methods in the AppSupport.framework that would get this information more easily, but that would definitely not be allowed in the app store.
As for the other part of this question (access the details of an incoming call), this would most likely be possible on a jailbroken phone. No doubt there's already a tweak in Cydia that does this.
Okay, I want to have an app that takes phone numbers from an online database and displays them in a table view. When the user is not online, I want them to still be able to see the numbers they already got from the database in the table view. If the user manages to go back online, the database updates the view. My question is, is this possible to do and if so, what's the best way to approach it? (bit of a newbie, please help me out)
There are many ways to do what you are asking, depending on the complexity of what you are after.
Could I suggest the following steps (I'm not sure which ones you can do, and which ones you are having trouble with).
Connect to the server and retrieve the list of phone numbers
If the database has a web server front end this might be as simple as sending a get request to the server (see NSURLConnection) and parsing the result. Otherwise you will need to know/tell us what type database you are using.
Store the phone numbers on the device
Use SQLite to store the numbers on the device (See iPhone SQLite Resources)
Check for internet connectivity
Periodically check for internet connectivity, and if a specific time has elapsed since you last polled the server, retry. (See Checking iPhone internet connectivity)
Although you’re probably looking for a native app solution, you can also do this with a web app.

I am a new developer iPhone developer, "learning" to be precise. I came across the useful NSUserDefaults (a dictionary in which you can store/restore state even after your application relaunches). Problem with this dictionary will be memory in your case. NSUserDefaults is sort of global to all applications and yours may spoil the show for other innocent applications (like Weather :D ).
To work around this, you can have your application declare a property list file where you store a few numbers (best practise would be the most recent but you can use any selector of choice). Look for an appropriate time in your run loop to store these numbers into your property file and load them when the application starts.
How do I send a push notification to a device at regular intervals, e.g. every x minutes?
[Tapping this out on my phone - hopefully the formatting is all right - I'll fix it later if necessary. Apologies in advance if it's messy...]
As others have pointed out, you'll want to look at Apple's docs for how to do this (it's not the most straightforward process in the world)..
What I wanted to contribute is the suggestion that you check this out: http://urbanairship.com/push/
Urban Airship takes care of a ton of the hassle you'd otherwise have to deal with yourself. You still need to be registered with Apple for sending push-notifications, but if you use Urban Airship's bits, they'll provide you hosting for your notification service, reporting, a management console, and a REST API for interacting with the system. They even have a scheduling component, and I'd bet that it would solve your problem here with just a few simple calls.
These guys are local to me (I live in Portland, Oregon), and I've seen a few of their demos - it's slick.
There are other features, but I think the ones listed are compelling enough to at least give it a look :)
It's obviously not required - you could do all this on your own, but the service they're offering is insanely good and affordable.
At the time of this writing, they have an "indie" account that will let you send 100,000 notifications through them a month for free. After that it's $.001 per notification (again, this appears to be per month - so, if I understand the terms right, you get 100,000 notifications for free each month, which is just awesome).
You can see the different pricing options here: http://urbanairship.com/plans-and-pricing/
I'm not affiliated with these guys in any way beyond having chatted with them at local geek events and having been offered, along with other attendees, free alcoholic beverages. But, as I don't drink, I'd like to think my judgment hasn't been affected by the psychology of gifting (fascinating subject).
So... it's worth it to at least take a look at what they're offering. And if anybody else has links to similar services, post 'em in the comments. Apple has given devs an amazing platform to play with, but they haven't made it very easy in places - it's cool to see shops like this making it more accessible.
In my opinion, of course :)
There is no "built in" way to do this just using APNS. You would have to have your push provider code do this for you.
In my case my push provider pulls rows from a DB table and sends them at the time specified. I would just insert another row back into the DB after I sent a message.
As for limit, everyone I have talked to says that there is in effect no limit.
