For exemple we set a UK  subdomaine for : www.igomorocco.com

www.uk.igomorocco.com

Does having a subdomains UK affect SEO in UK google results?

How this should be set up correctly?

Only if it's marked up properly and has distinct, unique content. Even if you do it right, the difference is only slight (depending on industry of course). If you're just thinking of clone stamping a US site with exactly the same content to a UK sub-folder and then expecting to get loads of free rankings, think again
