Question

I have implemented a navigationController from ViewController1 to ViewController2. I am getting the tittle of the ViewController1 in Back BarButton of the NavigationBar at ViewController2.

When i change the tittle of the Back BarButton in the ViewController2 the Tittle in the ViewController1 Changes.?

self.navigationController.navigationBar.topItem.title = @"";
self.navigationController.navigationBar.backItem.title = @"";

How Can i do that without Changing the Tittle of the ViewController1

Answer 1

您应该创建自定义UIBarButtonItem。

self.navigationItem.backBarButtonItem = [[[UIBarButtonItem alloc] initWithTitle:@"Your Title" style:UIBarButtonItemStylePlain target:self action:YOUR_SELECTOR] autorelease];

Answer 2

In ViewController1

-(void)viewWillAppear:(BOOL)animated {
       [super viewWillAppear:animated];
       self.navigationItem.title = @"someTitle1";
}

and in ViewController2

-(void)viewWillAppear:(BOOL)animated {
       [super viewWillAppear:animated];
       self.navigationItem.title = @"someTitle2";
       self.navigationItem.leftBarButtonItem = [[UIBarButtonItem alloc]
       initWithImage:[UIImage imageNamed:@"BACK_BUTTON_IMG.png"] style:UIBarButtonItemStylePlain 
       target:self action:@selector(YOUR_SELECTOR_METHOD)];
    }
