I\'d like an image to take up all of a navigation bar. This is the navigation that comes with a navigation based app. It appears on the RootViewController with the accompa

Answer 1

Just add this line .

 [self.navigationController.navigationBar setBackgroundImage:[UIImage imageNamed:@"NavBar.png"] forBarMetrics:UIBarMetricsDefault];

Bam! One line and done.

Answer 2

I used cmp's solution and added some logic to remove it as I only wanted a custom background image on home screen within on view appear.

HomeViewController.m

UIImage *image = [UIImage imageNamed:@"HomeTitleBG.png"]; 
UIImageView *imageView = [[UIImageView alloc] initWithImage:image];
imageView.tag = 10;

UIImageView *testImgView = (UIImageView *)[self.navigationController.navigationBar viewWithTag:10];

if ( testImgView != nil )
{
    NSLog(@"%s yes there is a bg image so remove it then add it so it doesn't double it", __FUNCTION__);
    [testImgView removeFromSuperview];

} else {
    NSLog(@"%s no there isn't a bg image so add it ", __FUNCTION__);
}

[self.navigationController.navigationBar addSubview:imageView];


[imageView release];

I also tried to use the suggested clearBackgroundImage method but couldn't get it to work so I gave the image a tag and then removed it in the other viewcontrollers on view will appear.

OtherViewController.m

UIImageView *testImgView = (UIImageView *)[self.navigationController.navigationBar viewWithTag:10];

if ( testImgView != nil )
{
    NSLog(@"%s yes there is a bg image so remove it", __FUNCTION__);
    [testImgView removeFromSuperview];  
}

just go the view controller and paste in super viewdidload and replace your image in mainlogo and then set the navigation title in set your image logo

  - (void)viewDidLoad
{
   [super viewDidLoad];

   //set your image frame
    UIImageView *image=[[UIImageView alloc]initWithFrame:CGRectMake(0,0,70,45)] ;

  //set your image logo replace to the main-logo
   [image setImage:[UIImage imageNamed:@"main-logo"]];

   [self.navigationController.navigationBar.topItem setTitleView:image];

}
