I’m have small app that simulate physics (box2d) and sending network data using pub nub.(Realtime sockets framework)
The issue is, when pubnub send the data, the sprite object (which get simulated by box2d) is stopped for a little and then continue.
This happen every time data is send.
I tried to it in another thread, but it continue to happen.
Any advice?
xCode 5, cocos2d 2.1
Update: FIXED.
Disable all logging
https://github.com/pubnub/objective-c/blob/master/iOS/README.md#logging
Disabling all logging fixes the issue! https://github.com/pubnub/objective-c/tree/master/iOS#logging to see how its done. Ping us again if any issues arise!

You probably want to check out the following guide.

this should give you some hints about how to communicate with bluetooth devices.

I would like to replicate the default clock app in my app. Is there any way i can use the default app in my application or i should create a new one inside my app.I would be needing the world clock function in my app , What is the best method to implement it? Thanks in advance.
No, you cannot re-use the current 'World Clock' app within your own. You are going to have to replicate this functionality yourself.
CocoaControls does have a number of open source 'clock' controls that you might find useful.

How do I send an array through the internet from an OSX computer to an IOS device, Sorry I don't know to much about Objective C I am planning on creation an application and I haven't yet started creating it.

What you basically want to do is use your OS X as a server. and then download information from there. If you are new to Objective-C I would recommend you read some tutorials before you get started.
Here you can find some general iOS tutorials: http://www.raywenderlich.com/tutorials
Here you can find one on NSURLSession (connecting to servers): http://www.raywenderlich.com/51127/nsurlsession-tutorial
Do some research before starting, or else it will probably result in a bad architected code. There also are several Stack Overflow questions with good references.

Thanks.
The only interprocess communication allowed by Apple on the AppStore is using URL handlers.
For more information, read here.
Using x-callback-url’s source apps can launch other apps passing data
and context information, and also provide parameters instructing the
target app to return data and control back to the source app after
executing an action.

How do you clear a Core Animation cache programmatically if any. With time, my app's performance gets very slow and the profile instrument tells me it's because of Core Animation. I was hoping if it will be possible to refresh core animation in my app from time to time.
I believe it is not a cache issue, even its if you mess up within this area you will have another issue, I suggest to run the profiler and check if you have a leak somewhere, make sure you are releasing all your ivars porperly, use
CGImageRelease(cgImage), CGPathRelease(path), ..etc
plus take a look here and here also
