UIBarButtonItem *yourButton = [[UIBarButtonItem alloc]
initWithTitle:@"Your Button"
style:UIBarButtonItemStyleBordered
target:self
action:@selector(methodName:)];
self.navigationItem.rightBarButtonItem = yourButton;
[yourButton release];
And then method
然后方法
-(IBAction)methodName {
// your code here
}

You should add UIBarButtonItem to Nav bar instead of UIButton. T do that you can call this:
您应该将 UIBarButtonItem 添加到导航栏而不是 UIButton。这样做你可以称之为：
UIBarButtonItem *button = [[UIBarButtonItem alloc]
initWithTitle:@"Title"
style:UIBarButtonItemStyleBordered
target:nil
action:nil];
self.navigationItem.rightBarButtonItem = button;

UIBarButtonItem *customBtn=[[UIBarButtonItem alloc] initWithTitle:@"Custom" style:UIBarButtonItemStylePlain target:self action:@selector(customBtnPressed)];
[self.navigationItem setRightBarButtonItem:customBtn];
///// called event
///// 调用事件
-(IBAction)customBtnPressed:(id)sender
{
//Your code here
}

if UIButton is you really want, try this.
如果你真的想要 UIButton，试试这个。
UIButton *btnSample = [[UIButton alloc] initWithFrame:btnFrame];
btnSample.backgroundColor = [UIColor blueColor];
UIBarButtonItem *barBtn_cart = [[UIBarButtonItem alloc] initWithCustomView:btnSample];
self.navigationItem.rightBarButtonItem = btnSample;
