I'm building a app that allows users to text in there photos to a twilio phone number which stores the photo on an AWS server.
However it appears the end photo is modified both in resolution and redacted exif data.
Does anyone know is this something Twilio is doing and can hopefully be switched off or is this happening during transit somehow?
I've tested from multiple phone models / os's and the results always seem the same which makes me think it twilio.
Maybe there is a better way to extract GPS data from a texted photo???

I am working on an app that needs to figure out someone's location in order to say buy a coffee from the Starbucks closest to them.
The app currently uses the Twilio API to receive a text from someone's phone and act on it. The app can get the number and possibly the zip code if available from the text message; however, is there a more reliable way to get someone's location to accurately determine the closest Starbucks to them?
No, and the zip code is not reliable. It is an approximation based on area code.
Possible look at WhatsApp but not heavily used in some countries.
Can I share my location or receive location information on WhatsApp?
I am trying to make an app where it tracks the usage of other apps. I already know that this is impossible to do by directly getting usage data from apps that do not belong to you. I am wondering if there is any way to access the battery page in the settings app by using the code in swift.
All I want is to be able to read the data for hours used and use that data in my app. I know this is probably a stretch, but is there any possible way of doing this?
There is no API to read this data directly.
There is an app on the App Store which has a hacky workaround. It requires users to take a screenshot of the battery usage settings page. The app grabs this photo from the user's photo library and uploads it to their servers where it is processed (using image analysis and OCR). They use this information to estimate how much each app is used.
I am trying to make a series of applications which require the user to make an account and login, therefore they could use the application on multiple devices and have the same data (e.g.. amount of virtual money and player score is about it), however, I have no idea how to go about this, I have decided it would be best for my app not use the apple GameKit (game centre) as it has a lot of limitations (e.g not showing usernames). What methods could I use to do this? Do I need to learn another language
Thank you
You can try Firebase, which serves as a backend especially for mobile applications. Basically, send a kind of a POST request to Firebase when the values you want to store have been changed in your game and send a kind of a GET request to fetch the said values to your mobile app(s). By this way, you can store data on Firebase and fetch it via multiple devices when the same user logs in from different devices.

I want to develop an iPhone application which can track the contents (such as location information, device hardware/sw information, contacts …etc) being collected from your device by all the applications and give a report to the end user at end of each week.
Because, I believe that end user should be notified about what information being collected by his device and sent to which servers to store them.
I Googled it and read few articles as well, but all pointed to the conclusion that a given application cannot (or restricted by Apple) peak into operations of other apps and collect any information about what those applications are doing.
But I've seen this Onovo Count app http://www.onavo.com/apps/iphone_count is collecting the data usage of all the other apps in your device, so can we just go few steps beyond that get this done ?
From the looks of it Onovo Count redirects all device traffic through a VPN. I presume their servers look at the host names of the traffic and record it against the device. When looking at the app, you're just looking at a dump of the data for your device.
For the rest of what you want to do, it is not possible on a standard device, you'd need to have it jail broken or something.
We switched over to YouTube from a previously developed internal video system, and right now I've got it going on public upload feeds for users. The problem comes when we first got only about a dozen out of 150 or so videos available from the primary user's account. Over time of the day that number rose to about 50, and its stayed there. I found one post on the YouTube API forums about delay, but no word on how long I can expect that.
Anyone have experience about this to tell me what to expect?
Expected latencies can vary, and are documented here (http://code.google.com/apis/youtube/2.0/reference.html) - ways you can minimize it:
1) Upload the video as public. If you upload the video as private first, this will leave the video out of the fast-track indexing
2) Make an authenticated request to the user feed, this will guarantee the freshest data that the API has.
ie. http://gdata.youtube.com/api/feeds/users/username/uploads (with a dev key and auth token for 'username') instead of http://gdata.youtube.com/api/feeds/videos?author=username
