How does ARC deal with local variable within the method?

For example,

- (void) method
{
    NSString *string = @"This is a string.";

}

Do I need to add

string = nil;

at the end of the method in order to let ARC release it?

Situation may be different in non-literal object such as

- (void) method
{
    NSData *data = [[NSData alloc] init];

}

Do I need to add at the end

data = nil;

to release it?

You don't need to nil it, but ARC doesn't release it either. Since it's a literal, it's statically allocated in the app's binary. It's never released.

- (void)method {

    NSString *string = @"I'm never released because I'm statically allocated";
    NSString *arcReleasesMeAfterMyLastSourceRef = [NSString stringWithString:string];
}
