Re: Strings, URL and path manipulation

[Ivan Vučica]

Looks like it works correctly (although I'd swear it shouldn't be normalizing 
the path as described, and that I've used it on strings with URLs). 

Test code:
NSLog(@"%@", 
[@"http://cs13-api.salesforce.com/services/Soap/u/25.0/00DW00000012fxX"; 
stringByDeletingLastPathComponent]);

OS X output:
2012-08-09 11:32:55.066 test3[2832:707] 
http:/cs13-api.salesforce.com/services/Soap/u/25.0

Why not find last slash and simply "substringToIndex:"? The only trouble arises 
if there is a query string, in which case you'd look up the first question 
mark, strip everything after it (including it), and then find the last slash. 

Or look up first two slashes, and strip everything before them (including 
them), so you get the protocol prefix and everything-but-protocol-prefix. Then 
use stringByDeletingLastPathComponent on everything-but-protocol-prefix. 
Finally append the result to the protocol prefix and you're done.
