ios - Transfer Multiple Images via NSInputStream/NSOutputStream -

i have 2 nsinputstream , nsoutputstream connected each other via network. want transfer core info objects , associated images 1 device other device. have converted core info objects json , transferred other side of stream , populated core info json. there images associated each recorded. images on disc, there path stored in core info objects. now, have have finish info @ hand when writing output stream. have xml (that contains json) ready. 1. how transfer images (nsdata *) along xml (also nsdata *) ? how differentiate @ reading end (nsinputstream) between xml , images? 2. also, have transfer multiple images, how tell @ nsinputstream end bytes of image have finished , the bytes of next image have started ? 3. how know image (name) has been transferred ? thanks

convert nsdata (of each uiimage) nsstring representation, set nsstring objects nsdictionary , serialize dictionary. in way when transfer info on can reverse process extract images knowing key points image. way should able transfer multiple images.

hope helps.

cheers
