Using @property and weak properties in Objective-C

I have a specific question, and I could not find an answer to it.

I have a storyboard that has some looks. Some of the species have exits. I understand that I should declare my access points weak parameters, but I do not know if I should declare recipients and setters (using @property and synhesize).

1 - __weak IBOutlet UITableView *table;
2 - @property(nonatomic, weak) UITableView *table;

If I just declare (1), I can just make a “table” on the view controller.

If I declare (1) and (2), I can do self.table.

Who cares? What is the best approach?

As a rule, there is no reason to declare withdrawal as a strong property, implying a right of ownership. Most of the views belong to their observations.

@property (weak) IBOutlet UITableView *table;

Then you process like any other property

@synthesize table = _table;
- (void)someMethod
{
     [self.table doSomething ....]
}
