UINavigationItem（你想在这里使用的）有一个rightBarButtonItem，你可以设置。

做这样的事情：

UIBarButtonItem *rightCornerButton = [[UIBarButtonItem alloc] 
                initWithImage:[UIImage imageNamed:@"myAwesomeImage.png"] 
                style:UIBarButtonItemStylePlain target:self 
                action:@selector(functionYouWantToRunWhenBarButtonIsPressed)];
[self.navigationItem setRightBarButtonItem:rightCornerButton];
// If you do it this way, the button will disappear when you call -pushViewController on your navigationController.
[rightCornerButton release];

甚至更好（移除框架）：

UIButton *barButton = [UIButton buttonWithType:UIButtonTypeCustom];
[barButton setImage:[UIImage imageNamed:@"reload1.png"] forState:UIControlStateNormal];
UIBarButtonItem *rightCornerButton = [[UIBarButtonItem alloc] initWithCustomView:barButton];
[rightCornerButton setTarget:self];
[rightCornerButton setAction:@selector(functionYouWantToRunWhenBarButtonIsPressed)];
[self.navigationItem setRightBarButtonItem:rightCornerButton];
// If you do it this way, the button will disappear when you call -pushViewController on your navigationController.
[rightCornerButton release];
