initwitharray VS arrayWithObjects

InitWith Object Syntax:
NSArray *bar = [[NSArray alloc] initWithObjects:@"hai",@"how",@"are",@"you",nil];

Array With Objects Syntax:

NSArray *tempArray = [NSArray arrayWithObjects:@"hai",@"how",@"are",@"you",nil];

Result= return [[[NSArray alloc] initWithObjects:@"hai",@"how",@"are",@"you",nil] autorelease]

So here the array returned is auto-released. Thats the only difference.
