It's in the eye of the beholder. From where I'm standing, it's deeply consistent -- NSData is my go-to class for writing N bytes of arbitrary data to a file. Why is N==0 an abuse?
Also, if I create a mutable data object:
NSMutableData* dataBuffer = [NSMutableData data];
then I can use it to create the file and then re-use it as the data buffer I need to pass to [NSFileHandle writeData:].
With this technique, I've reduced the number of lines of boring housekeeping code needed to create the file and set up a data buffer I wanted anyway. Concision is good.
With this technique, I've abstracted my task -- writing data bytes to a file in one or more pieces -- away from a series of lower level tasks (interacting with a file system) that have no particular interest. Abstraction is good.
Finally, you don't have to guess that it works. It's a line of code I've used many times. When posting code here to save you a little time and effort, I wouldn't waste your time suggesting doubtful code.
