[self.navigationController.navigationBar setBackgroundImage:imag forBarMetrics:UIBarMetricsDefault];
//button 定义你要的背景 文字 或 事件
UIBarButtonItem *leftBarButton = [[UIBarButtonItem alloc] initWithCustomView:button];
self.navigationItem.leftBarButtonItem = leftBarButton;
[leftBarButton release];
具体实现:
[self.navigationItem
setTitle:@"通知详情"];
//self.navigationController.navigationBarHidden = NO;
[self.navigationController.navigationBar
setBackgroundImage:[UIImage
imageNamed:@"root_top.png"]
forBarMetrics:UIBarMetricsDefault];
self.navigationItem.hidesBackButton =

UIButton *rightButton = [[UIButton
alloc]initWithFrame:CGRectMake(SCREEN_WIDTH -
70, 10,
70, rootTopHeight -
20)];
[rightButton addTarget:self
action:@selector(NoticeBackAction)
forControlEvents:UIControlEventTouchUpInside];
[rightButton setBackgroundImage:[UIImage
imageNamed:@"root_back.png"]
forState:UIControlStateNormal];
[rightButton setTitle:@"退出"
forState:UIControlStateNormal];
UIBarButtonItem *rightBarButton = [[UIBarButtonItem
alloc]initWithCustomView:rightButton];
self.navigationItem.rightBarButtonItem = rightBarButton;
