Answer 1

Here's how I implemented the UIButton inside of the UIBarButtonItem:

UIButton *logoButton = [UIButton buttonWithType:UIButtonTypeCustom];
[logoButton setImage: [UIImage imageNamed:@"icon.png"] forState:UIControlStateNormal];
logoButton.frame = CGRectMake(0, 0, 30, 30);
[logoButton addTarget:self action:@selector(showAbout:) forControlEvents:UIControlEventTouchUpInside];
UIBarButtonItem *barItem = [[UIBarButtonItem alloc] initWithCustomView:logoButton];
self.navigationItem.rightBarButtonItem = barItem;
[barItem release];
