Get all characters after the last '/' (slash) from url string

Question

How to get all characters after the last '/' (slash) from url string?

I receive a json string from my URL scheme when making webview request for certain site. For example:

app://ga/ecommerce/%7B%22product%22:%22playstation4%22...}]

I would like to grab the substring after the last '/'(slash).

How can I achieve it? May I know what is the format of Regex?

Avoid to use

NSRange lastDotRange = [sURL rangeOfString:@"/" options:NSBackwardsSearch];

because I might have escaped '/' in my json.

Thank you.

For Swift 3 try this.

let fileName = "your/file/name/here"
let fileArray = fileName?.components(separatedBy: "/")
let finalFileName = fileArray?.last

Output : "Here"

try this:

    NSURL *url = [NSURL URLWithString:@"app://ga/ecommerce/%7B%22product%22:%22playstation4%22..."];
    NSString *last = [url lastPathComponent];
