My question is simple, at least that is what i think :)
I need to extract something like this: 01816560 from something like
this: http://www.xxxx.com/diario/2008/12/05/um/m-01816560.htm My
first idea was to use - (NSArray
*)componentsSeparatedByString:(NSString *)separator with - first (to
get the 01816560.htm and then - (NSArray
*)componentsSeparatedByString:(NSString *)separator again with '.'
But i am quite sure it should be a better way to do just that. Any
idea?
It entirely depends on how the URL can change.
If the URL is always the same format, then you could just use
substringWithRange with an appropriate range.
If the URL can change somewhat, and it is just the last component,
then you could use lastPathComponent to get the last piece, and
stringByDeletingPathExtension to remove the extension.
After that, how you get rid of the m- depends on how that part changes.
Ultimately, you could use a regex library, but while I find that
indispensable, its probably overkill for this task.
Enjoy,
Peter.
