I have an idea to use a telegram bot for food ordering from a smartphone. So, you have a menu, prices, there is a payment gateway. This part seems clear to me.
I was wondering if there any way to get a geolocation information inside telegram? So smartphone owner location is sent automatically.
The alternative I see are:
writing address thru telegram (too much work and probably restaurant has to call back);
Install a small Android/iOS app just to send a location to the service. Kinda feels awkward, but a little better that first option.
Maybe you can see better ways, perhaps telegram already got some related functionality?
Thank you!
On some step (don't do it too early) you can send a button with the request_location field set to true.
When the user presses that button, Telegram asks the user if he wants to share his location with the bot.
The user then sends a location. Note that the user could also spoof the location.

I am developing an mobile app for iPhone. The app will primary used by people who are on holiday in a different country and will be offline most of the time, due to high costs for internet traffic.
However, the company for which I am developing the app wants to users to be able to use the "Facebook Share" functionality also when people are not connected to the internet.
It should work on a way that they click the SHARE link button in the app, but then get a message that they are offline and the link will get shared as soon as they are online again.
I am trying to figure out how to do this. Can I pass the link I want to share to the official FB App via fb:// protocol (or whatever) and the FB App handles the post/share as soon as it is online again?
Or do I have to do it on my own, put the links I want to share in a internal database and then post them to the wall when I am online again?
Or any other ways??
Any suggestions would be welcome, I would prefer a very quick solution and hope someone maybe has an idea how to do this. I was hoping I can pass the share-link to the official FB App and this one handles everything when it goes online again !?
Thanks for your ideas!
Your approach should be to make your link-sharing code automatically cache requests until they are sent. The app then doesn't need to concern itself with the details - it can just post the link and get a 'failed', 'success', or 'postponed' response from your API and notify the user accordingly.
Your link-sharing code can then internally check if it can currently post to FB and if not (either because the user is currently offline or perhaps the Facebook token is expired) it will store it for later. This class will then re-check periodically (for example when the app comes to the foreground or when the class is initialised the next time the app starts) for connectivity and then it will check if the token is still valid and perform FB login if required. Once it has a valid token it can then iterate through the pending requests and act upon them.
If you really want to make it nice and clean, you can separate out the code that accepts incoming requests to do something, checks if it can be performed now, does it or stores it for later, and periodically checks any requests in the pending queue. This class will not have any idea what the requests do or how they are performed, it will work with another class that implements a protocol to do the actual work and knows about facebook, etc. There may even be an existing design pattern for such a setup, but I don't know what it's called if there is.
Update: I did some research and found this is very similar to the "Fire-and-Forget Pattern".
After registration, our app prompts users to invite her friends (aka phone contacts) to use the app too. This allows us to send an email/sms to the useer's contacts with some sort of invitation key. Works fine for a web version app, just embed the key in the url you provide in the invitation.
I'm having trouble figuring out how to make this work smoothly with IOS only. It would be brilliant if I could send the invitee a link to appstore.apple.com/myapp?registrationKey=abcXYZ and have the key magically available to my app once it's installed, but I guess this is a lot to hope for?
The obvious way around this is to make the user manually enter their registration key on first launch, but this seems less reliable and (to my mind) adds friction to the UX.
Has anybody come up with something clever to get around this?
Here is what is flowing through my brain on how to solve this solution, please note, I have not vetted, psudeo-coded, coded, or applied this theory.
Since you will know who is being sent an invitation, save that data to your database with a relationship to the user sending and a unique id to the user being invited (email address if its in the contact's card). When new users sign up scan the database for invitations, if one is found present it to the user asking We're you referred by <existing user>? Once the new user selects their response continue through the registration process, updating the relationship table accordingly and applying any extra settings you need to for the referral.
This combines automatic referral tracking with referral codes for a basic, straight-forward, almost (but not quite) fool proof method to make sure referrals are linked to the right users.
As far as I can tell, the App Store provides an information firewall between an invitation and the installed app.
The closest workaround I've seen is the following:
email link sends you to your website
the website logs reference information in the URL and the IP address
the website instantly redirects you to the App Store (if iOS detected)
user installs the app
user loads the app
app contacts your website, IP addresses matched ... BINGO
Obviously not a secure method though.
There are many failure cases:
business networks commonly share IPs
home and mobile networks release and reuse IPs
The more is frequently used to resolve cases where its good enough to know that the user 'almost-certainly' was referred to download app by the email.
For example, it can be a good mechanism to prompt the user with a "who do you know" question in an app and limit the options based on the (IP+reference) data. If they pick the original poster, then maybe that's good enough, and then you can attach any other data that the inviter provided.
(Full disclosure, currently work at Branch)
The best solution to this is to fingerprint a user. This requires you to do the following steps:
For each user, using your own domain, generate a link for said user. So, right when they complete registration, generate their unique URL, that contains the invitation key.
For anyone clicking this link, they will redirect to Safari first. When they do, capture their IP address and iOS operating system version from the headers and user-agent.
Save this data on your server, and set window.location to your iTunes url.
If the user downloads and consequently opens, inside AppDelegate.m, send a message to your server with the IP address + major/minor/min version you collect upon app launch. If it matches with what you have on the server, you can now pass that invitation key back to the new user.
It's not perfect, and has the ability to misattribute. You could also use branch.io, where all of this is taken care of (link-generation, fingerprinting a user, attribution). Branch also drops a first party cookie and ties it with the device level ID, so attributions are much more accurate.
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.
I'm developing my first iOS app and I'm facing a challenge.
I'd like to present new users a personalized screen when the app starts at the first time. Let me explain more.
The flow should be more or less like this:
My app isn't installed on the user's device.
Then the user gets an SMS on his iPhone with a short message and a link to install my app. The message is part of a conversation. Another user of this app had sent this message (through my backend) in order to join this user to the conversation.
This install URL doesn't necesarrily link directly to the itunes store, it can link to a conversations specific link such as myapp.com/conv/12345
The page at myapp.com/conv/* will detect the device and if it's an iPhone would redirect the user to the appstore to install myapp.
The user then installs myapp and launches it.
Now I'd like to present the same conversation 12345 to the user, before he even needs to login, register or what have you. That's the difficult part... I don't want the user to start an a blank page, I'd like to take it right to the conversation 12345 page.
I assume steps 1-5 are easy, but I can't think of a way to implement 6. I admit that I'm not familiar enough with the intrinsic of the appstore but as far as my understanding goes, "all apps are made equal", I mean the app itself when it gets installed it has no context, it doesn't know what "caused" it to be installed, it isn't aware of the click on myapp.com/conv/12345. Is this correct?
If there was a way for an app to know something like a referrer URL for the instllation or something along these lines that would be awesome.
If there was a way for app to query the device for its phone number
then I could make this work (b/c the SMS was sent to a specific phone
number, so I can track the most recent conversation sent to this
number on my backend). But since apps are sandboxed, accessing the phone
number is off limit.
Well, I suppose I could ask the user to type a unique code from the SMS when the
app starts, say 12345 and then I'd be able to display the
conversation to him. But that's problematic in two ways, first,
security - the user can join a conversation not meant
for him, and second, that's less than optimal
user experience, I want this to work like magic, I don't want to make
users memorize and type strings into my app the first time they
install, I'm sure they won't appreciate it... (they could
copy-paste, but still...)
Another option is asking the user to type his phone number. But that
again has a few drawbacks, one is that again it's less than optimal
UX, I'm asking a user to type his phone number to an app he doesn't
yet know or trust, second I'll need to verify (authenticate) the
phone number, I mean what prevents that user from typing a phone
number that doesn't belong to him?
If I had access to the SMSs then I could dig up that code, but I find
it hard to believe that apps get access to SMSs, it's just sounds
like another reasonable sandbox restriction. Of course I'm not
speaking of jailbroken devices.
BTW, if the user just went over to the appstore to install my app (and didn't go through a conversation SMS) that's fine, in this case I'll just present a normal register/login page. The interesting case is where the user was already part of the conversation when receiving the SMS and now I want him to (effortlessly) become part of the same conversation through my app.
To sum up - is there a trick to present "personalized" pages the first time an app is installed and launched that would get that user right into the context of the conversation sent to him over SMS without having to request additional input?
Thanks!
It's impossible to do. Your application is installed without the knowledge you need whatsoever. As you pointed out, it's a reasonable sandboxing restriction.
What you could do is a challenge-response based system, but it would be about as intrusive to the user as is registering/login in.
Ran, you can keep a flag in NSUserDefaults (equivalent to Android's SharedPreferences)

I need a script that will add my phone with Twitter for All latest notification.
I found this page Twitter but i need to create script for my own application.
I goggled but i didn't get any solution For this.Please Help me to find this answer.
Thanks a lot in advance.
First Edit
This is a twitter's new feature Send notification to Phone. Actually I want to create an app that will allow users to register there phone with twitter via my application. Ie I need a script to implement send notification to phone.
The question that others are asking you Pankaj is what platform is your application being written for. You keep saying you want a "script" to do this, but what kind of script?
Giving us more insight to what your application is (a console application written in C#, or an ASP.NET web application) would lend more detail and raise the chances of someone being able to help you. :)
Regardless of your app's platform though, you're probably going to need to look into the Twitter API for setting this up. This is the normal method to interact with Twitter from 3rd party applications. So all the suggestions above, specifically the list of API's available, is probably what you're looking for.
Hey, can you give some more information? What kind of Phone are you developing for?
Maybe that helps solving your Problem.
If you are just searching for a way connecting your Phone to Twitter, here is the Twitter FAQ for Phone connecting:
http://support.twitter.com/articles/14014-twitter-phone-faqs
Maybe it helps, or give you more keywords for your search.
I don't believe there's a way to get or set the notification phone number using the API, however if a phone is already setup on the profile you want to configure, you can do the following to get notification from all user friends.
The user will need to authorize your application to access her account. This flow uses OAuth, and begins here:
http://api.twitter.com/oauth/request_token
Once the user has granted your app access, and your application has all the required OAuth credentials, turn on notifications using account/update_delivery_device:
http://api.twitter.com/1/account/update_delivery_device.json?device=sms
Next, fetch all the IDs for your user's friends using the friends/ids API call. Be sure to study the documentation; this call uses cursors, so you will have to manage those if the user has over 5,000 friends. Store these IDs for use in the next step. Here's an example call:
http://api.twitter.com/1/friends/ids.json?cursor=-1
Once you have all of the friend IDs, you can call notifications/follow repeatedly to enable notifications on your mobile device whenever your friend makes an update:
http://api.twitter.com/1/notifications/follow.xml?user_id=12345
This approach will burn one API call for each user that you enable notifications for; there's no way currently to manage notifications en masse.
