NSString to Image

I need some help converting a NSString which represents an Image file sent from an iOS device.

The image is the signature for a credit card transaction.

I am receiving all of the data as a CFString on the Mac side.

How can I convert it to an image that I can use in FB?

This is how the data is formatted when sent with other data about the transaction.

  NSData *sigData = UIImageJPEGRepresentation(delegate.signature, 1.0);

	NSString *sigDataString = [NSString stringWithFormat:@"%@", sigData];

	myString = [myString stringByAppendingString:@" Signature :"];

	myString = [myString stringByAppendingString:sigDataString];

	myString = [myString stringByAppendingString:lineFeed];

    NSLog(@"%@", myString);

	NSString *cardDataSend = [NSString stringWithFormat:@"%@rn", myString];

	NSData *cardData = [cardDataSend dataUsingEncoding:NSUTF8StringEncoding];

	[asyncSocket writeData:cardData withTimeout:-1 tag:0]; //write data to server

thanks
