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

try this:

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

For Swift 3 try this.

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

Output : "Here"
