Answer 1

Try this.

UIBarButtonItem *leftItem = [[UIBarButtonItem alloc]
                                initWithTitle:@"Left"
                                style:UIBarButtonItemStyleBordered
                                target:self
                                action:@selector(leftItemAction)];
UIBarButtonItem *rightItem = [[UIBarButtonItem alloc]
                               initWithTitle:@"Right"
                               style:UIBarButtonItemStyleBordered
                               target:self
                               action:@selector(rightItemAction)];
self.navigationItem.rightBarButtonItem = rightItem;
self.navigationItem.leftBarButtonItem = leftItem;

- (void)leftItemAction
{
...
}

- (void)rightItemAction
{
...
}
