Try using the hasPrefix method:
if([test hasPrefix:@"three"])
{
// Begins with three
}

For a more general approach, get a relevant substring, and compare it with the desired result.
if ([[test substringWithRange:NSMakeRange(0,5)] caseInsensitiveCompare:@"three"] == NSOrderedSame) {
// ....
}

It's done by
if([test hasPrefix:@"three"]){
...
}
General answer: whenever you want to check if NSString (or any Apple-provided class,) look up the official documentation! In this case, see here. You see, there's not only StackOverflow on the internet, there's the official documentation!

You need to use the following:
if ([test hasPrefix:@"three"])
{
// if YES
}
