I am connected to the networked...
I have a fairly large NSData (or NSMutableData if necessary) object which I want to take a small chunk out of and leave the rest. Since I'm working with large amounts of NSData bytes, I don't want to make a big copy, but instead just truncate the existing bytes. Basically: NSData *source: < a few bytes I want to discard > + < big chunk...

Hey all! I'm using ASyncSocket to move some UIImages from one device over to another. Essentially, on one device I have: NSMutableData *data = UIImageJPEGRepresentation(image, 0.1); if(isRunning){ [sock writeData:data withTimeout:-1 tag:0]; } So a new image will be added to the socket every so often (like a webcam). Then, on ...
Hi I am working on a e-banking iphone application. I am using WSS with XML-Signature to sign the requests to the customer's SOAP server. Since the iPhone device can not be trusted (due to jail-breaking), the customer requirement is to manually encrypt the RSA key pair (using AES128) before storing the keys into keychain. From what I ...
