@property/@synthesize question

I'm going through all of my documentation regarding memory management and I'm a bit confused about something.

When you use @property, it creates getters/setters for the object:

.h: @property (retain, nonatomic) NSString *myString

.m: @synthesize myString

I understand that, but where I get confused is the use of self. I see different syntax in different blogs and books. I've seen:

myString = [NSString alloc] initWithString:@"Hi there"];

or

self.myString = [NSString alloc] initWithString:@"Hi there"];

Then in dealloc I see:

self.myString = nil;

or

[myString release];

or

self.myString = nil;
[myString release];

On this site, someone stated that using self adds another increment to the retain count? Is that true, I haven't seen that anywhere.

Do the automatic getters/setters that are provided autorelease?

Which is the correct way of doing all of this?

Thanks!
