Answer 1

You can also use

NSString *sub = [@"http://www.abc.com/news/read/welcome-new-gig/03276" lastPathComponent];

Answer 2

If you know how many characters you need, you can do something like this:

NSString *string = @"http://www.abc.com/news/read/welcome-new-gig/03276";
NSString *subString = [string substringFromIndex:[string length] - 5];

If you just know that it's the part after the last slash, you can do this:

NSString *string = @"http://www.abc.com/news/read/welcome-new-gig/03276";
NSString *subString = [[string componentsSeparatedByString:@"/"] lastObject];

Answer 3

Since *nix uses the same path separators as URL's this will be valid as well.

[@"http://www.abc.com/news/read/welcome-new-gig/03276" lastPathComponent]

Answer 4

If you know the length of the number, and it's not gonna change, it can be as easy as:

NSString *result = [string substringFromIndex:[string length] - 4];
