Adding back button to navigation bar

Question

I\'ve added a navigation bar to a UIViewController. It is displayed from another UIViewController only. I\'d like to have a left side back button that is shaped similar to

Answer 1

I have done it the following way

In viewDidLoad Method I have this code:

UINavigationBar *navBar = [[UINavigationBar alloc] initWithFrame:CGRectMake(0, 0, [UIScreen mainScreen].bounds.size.width, 41)];
    navBar.delegate = self;

    UINavigationItem *backItem = [[UINavigationItem alloc] initWithTitle:@"Back"];
    [navBar pushNavigationItem:backItem animated:NO];
    [backItem release];

    UINavigationItem *topItem = [[UINavigationItem alloc] initWithTitle:@"Your Title"];
    [navBar pushNavigationItem:topItem animated:NO];
    topItem.leftBarButtonItem = nil;
    [topItem release];

    [self.view addSubview:navBar];
    [navBar release];

Then add conformity to UINavigationBarDelegate protocol in the header and implement the delegate method this way:

- (BOOL)navigationBar:(UINavigationBar *)navigationBar shouldPopItem:(UINavigationItem *)item
{
    //if you want to dismiss the controller presented, you can do that here or the method btnBackClicked

    return NO;
}
