Answer 1

In addition to Rijo answer. No need to create NSURL instance, you can use lastPathComponent method of NSString:

NSString *filename = [@"http://stackoverflow.com/questions/ask/abc.pdf" lastPathComponent];

Answer 2

Use the lastPathComponent method of NSURL.

NSURL *url = [NSURL URLWithString:@"http://stackoverflow.com/questions/ask/abc.pdf"];
NSString *filename = [url lastPathComponent];
