iOS remove all characters after the last period in a string

Question

I have a string, something like "www.vanityURL.myWebsitesURL.com" and I want to strip off the extension, wether it is ".com", ".net", ".ru", etc... so how can I strip everything AFTER the LAST period?

Answer 1

Try this way:-

NSString* sURL = @"www.vanityURL.myWebsitesURL.com";
NSRange lastDotRange = [sURL rangeOfString:@"." options:NSBackwardsSearch];
if (lastDotRange.location != NSNotFound) {
    return [sURL substringToIndex:lastDotRange.location];
} else {
    return sURL;
}
