You can use the method [NSString stringWithFormat:@""] to format your URL string. For example,

NSURL *URL = [NSURL URLWithString:[NSString stringWithFormat:@"http://e.com/?var=%d", 2]];

If you look in the documentation for string format specifiers you can find out exactly what characters to use for each type of replacement (integer, double, object, etc).
