Every once in a while, there’s a feature in Objective-C that I really appreciate — the kind of method that makes you think, “Yes! Of course that should be in there!”, but yet at the same time it is surprising, because because in the past I would pretty much always have to roll my own algorithm for dealing with the particular problem.
The instance of this that I had in mind is with regard to the lastPathComponent method of NSString.
It is so convenient to be able to just get the name of a file from a path just by doing the following:
NSString* fileName = [myPath lastPathComponent];
In the past, on other platforms and languages, I typically had to write a routine that would loop through and find the last path delimiter and grab the final part of the string based on that location.
Now?
One method. Awesome.
