为UITabelViewController 加入 UINavigationController

1. 

UIBarButtonItem *barBuItem = [ [ UIBarButtonItem alloc ] initWithTitle:@"left" 

style:UIBarButtonItemStyleDone target: self action:nil ];

 

UIBarButtonItem *barRightItem = [ [ UIBarButtonItem alloc ] initWithTitle:@"right" 

style:UIBarButtonItemStyleDone target: self action:nil ];

   

navCtr = [ [ UINavigationController alloc ] initWithRootViewController:self ];

        

navCtr.navigationBar.topItem.leftBarButtonItem = barBuItem;

navCtr.navigationBar.topItem.rightBarButtonItem = barRightItem;

 

 

 

2. 

 

  UINavigationBar *navigationBar = [ [ UINavigationBar alloc ] initWithFrame:CGRectMake(0, 0, 320, 44) ];

  [ navigationBar setBarStyle:UIBarStyleBlackOpaque ];

 

  UINavigationItem *navItem = [ [ UINavigationItem alloc ] initWithTitle:@"FireWall" ];

 

UIBarButtonItem *barBuItem = [ [ UIBarButtonItem alloc ] initWithTitle:@"left" 

style:UIBarButtonItemStyleDone target: self action:nil ];

 

UIBarButtonItem *barRightItem = [ [ UIBarButtonItem alloc ] initWithTitle:@"right" 

style:UIBarButtonItemStyleDone target: self action:nil ];

   

 

  navItem.leftBarButtonItem = barBuItem;

  navItem.rightBarButtonItem = barRightItem;

  [ navigationBar setItems:[ [ NSArray alloc ] initWithObjects:navItem, nil ]];

 

  [ self.view addSubview:navigationBar ];
