How to set a picture programmatically in a NavBar?

Question

I have a detailview with a navigation bar with a back button and a name for the view. The navigation bar is set programmatically. The name presented is set like this.

self.title = NSLocalizedString(name, @"");

The name depends on the presented view.

Now I would like to also present a small icon on the navigation bar which also is depends on the view.

How do I do that?

Answer 1

You can set backGround image to navigationBar Using this

Put in didFinishLaunchingWithOptions

[[UINavigationBar appearance] setBackgroundImage:[UIImage imageNamed:@"title_bar.png"] forBarMetrics:UIBarMetricsDefault];  

Or you can set navigation bar image in any view using

UINavigationBar *navBar = [[self navigationController] navigationBar];
    UIImage *image = [UIImage imageNamed:@"TopBar.png"];
    [navBar setBackgroundImage:image forBarMetrics:UIBarMetricsDefault];

Or you can set a view on your NavigationBar Link

[[UINavigationBar appearance] addSubview:yourView]; 

or

self.navigationItem.titleView = YourView;  

And set title using h

self.navigationItem.title = @"Your Title"; 

And you can get navigationBarButton using this

-(void)getRightBarBtn
{
    UIButton *Btn =[UIButton buttonWithType:UIButtonTypeCustom];

    [Btn setFrame:CGRectMake(0.0f,0.0f,68.0f,30.0f)];
    [Btn setBackgroundImage:[UIImage imageNamed:[NSString stringWithFormat:@"yourImage.png"]]  forState:UIControlStateNormal];
    //[Btn setTitle:@"OK" forState:UIControlStateNormal];
    //Btn.titleLabel.font = [UIFont fontWithName:@"Georgia" size:14];
    [Btn addTarget:self action:@selector(yourBtnPress:) forControlEvents:UIControlEventTouchUpInside];
    UIBarButtonItem *addButton = [[UIBarButtonItem alloc] initWithCustomView:Btn];
    [self.navigationItem setRightBarButtonItem:addButton];
}

And set simple imageView on navigation Bar

UIImageView *image = [[UIImageView alloc]initWithImage:[UIImage imageNamed:@"star.png"]];
UIBarButtonItem *backBarButton = [[UIBarButtonItem alloc] initWithCustomView:image];
self.navigationItem.rightBarButtonItem = backBarButton;
