I make youtube app for iphone. When my app state in background i want to get notification.
How to receive the notice on the come messages from youtube through ios push notification service? tnx!
Does Youtube provide push notifications? You'll have to figure out how they register devices, and use the same method in your own app. Alternatively, you'll want to set up your own push server that scrapes Youtube or uses an API to interface with Youtube, so that it knows when to send push messages.
well you would need to use the JSON feed they have to get the info (ping it every 10/30 minutes via cron then if it sees a new video get it to send the message, if you search "advance ios apns" you will get a site/script that will send the notifications for you (to the apple devices)

I want to develop an iOS app which can upload an image from the device to be processed in an HIT on Amazon Mechanical Turk and the text result can be relayed back to the iOS device.
I know there is no native iOS API for Mechanical Turk, but is there a way to go around that by using something else perhaps?
Thanks!
You shouldn't use the Amazon API directly from your app, because in that case you would need to distribute your AWS access key & secret with the app. (I'll let you figure out why this would be bad thing)
You need a backend for your app, from where you'd send work items to the Amazon service, and notify the iOS app instance upon completion.

I have to do two way walkie talkie iOS app.. I searched a lot got information about 'push to talk service'. But can't get clear idea. May anyone can help me? How it works by iPhone for a particular channel... I got a iTunes link
https://itunes.apple.com/us/app/two-way-walkie-talkie/id595560554?mt=8
Can anyone tell me how this app works? Is they recorded and send voices to other user or they are sending live audio ? Also they are not getting any information from user..
Most walkie talkie apps are done by sending recorded audio file instead of sending live audio stream.
If you want to implement a record-and-forward type walkie talkie, you need to have a backend file server for storing temporary audio files which can be downloaded by the receiver side.
If you choose the hard way, i.e, sending live audio stream, it's another level of complexity. You're look at implementing literally a VOIP app. You may use PJSIP for your VOIP core functionality. However, you might end up spending months on the project in this case.
Personally, I strongly recommend you to go with the first one.

I have read about what most people say that it is not possible to create iOS applications for the app store that is able to record calls as there are no public frameworks available that has this function. In this situation it means to record phone calls directly using the default phone app provided by Apple.
However, I have also came across several app store applications that records phone calls. While there are no public frameworks that that are able to record calls, I believe these applications in the app store uses VOIP (such as Viber). I know the difference between VOIP and direct call recording that VOIP delivers voice communications over Internet Protocol (IP) networks, such as the Internet.
My question is how VOIP is called from code in applications. Is VOIP called from some public frameworks since private frameworks are not allowed in the appstore?
Edited: Removed 2nd question
These apps are not recording Phone.app calls from the device. Think of it like Skype or a similar service for your computer. Although your computer cannot make calls, services can use VOIP (Voice Over IP) to send audio data to a server. The same thing is happening with these App Store apps.
A user downloads a call recording app on the App Store.
The user makes a phone call to someone from WITHIN THE APP THEY DOWNLOADED.
The app starts sending voice data to the server and THE SERVER proxies the call to the destination number. You will notice that the interface for the "end call" button and dial pad are different, this is because Phone.app is not being used.
Now that the app is just sending it's own audio data, it has access to and can record it.
The open source application, siphon, is a great example of how VOIP can be implemented using Objective-C in an iOS app.

I need to create a live event with specific dates and scheduled times on Youtube. The content itself is pre-recorded video, but I want to showcase it in a "live" manner so that users can't skip ahead. After each individual live event comes to a finish, I then want the video to be archived so users can freely watch it on our youtube channel.
Any help or info would be greatly appreciated!
Do you have to do it via youtube itself ? If yes, then you will have to enable "Live" streaming feature in your account. Looks like you will have to be eligible to have it enabled.
http://www.youtube.com/live/all
If its enables, you can push your pre-recorded video files to the google's publishing point. For that you can use any supported media encoders. More info can be read here on how to set it up.
https://support.google.com/youtube/answer/2907883?hl=en&ref_topic=2853713
Once thats setup, you can stream events as if its a real live event !

I want to connect to facebook chat from my delphi application , change the status message or post something on the wall? Do u know any way i can acomplish this ?
If you want to connect to Facebook Chat with Delphi, check out this XMPP library for Delphi. Facebook chat uses XMPP as its communication protocol.
If what you want is change your Facebook status or post some stuff to the wall, you need to use Facebook API through Delphi. Maybe taking a look al Delphibook might help.
Face book chat uses the XMPP or Jabber Protocol
