Do I need to release NSString generated using @“…”?

Question

If I make an NSString using the code below, do I need to need to release someString?

NSString *someString = @\"somestring\";

Answer 1

I checked this case is different from NSString *someThing = @"someThing"; they should release urlString because of

[[NSString alloc] initWithFormat:@"%@%@", baseURLString, queryTerm];

Anywhere you use alloc/init you release it no mater what.
