Question

Answer 1

What I usually do is

1. Hide Navigation Bar
   [self.navigationController setNavigationBarHidden:YES animated:NO];

2. Use image of size 640 x 88 & 320 x 44
   UIImage *navigationImage = [UIImage imageNamed:@"navigationImage.png"];

3. Use this image in Imageview at frame CGRectMake(0,0,320,44)
   UIImageView *navImageView = [[UIImageView alloc] initWithFrame:CGRectMake(0,0,320,44)];
   navImageView.image = navigationImage;
   [self.view addSubview:navImageView];

Answer 2

I have tried and got the below solution,

func addIconToNavigationBar(){
    let logoContainer = UIView(frame: CGRect(x: 0, y: 0, width: 100, height: 30))

    let imageView = UIImageView(frame: CGRect(x: 0, y: 0, width: 100, height: 30))
    imageView.contentMode = .scaleAspectFit
    let image = UIImage(named: "FlashScreenTitle")
    imageView.image = image
    logoContainer.addSubview(imageView)
    navigationItem.leftBarButtonItem = UIBarButtonItem(customView: logoContainer)
}

In the above solution, I have Created a UIView and added ImageView inside that View. Then Created custom BarButtonItem, with my UIView and assigned it to the leftBarButtonItem.

Remember to call addIconToNavigationBar() in viewDidLoad() method

UIBarButtonItem *logoItem1 = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemAction target:self action:nil];
UIBarButtonItem *logoItem2 = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItem target:self action:nil];

NSArray *actionButtonItems = @[logoItem1, logoItem2];
self.navigationItem.rightBarButtonItems = actionButtonItems;

Answer 4

Try it like this:

self.navigationItem.titleView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"logo"]];

Also make sure UIImage is not nil and it does have a valid image.

Answer 5

Insert the Bar Button Item into your Viewcontroller on left Side, and insert the image in Bar item see the image

Answer 6

I think this is the problem with image rendering mode. Can you try the below code

    UIImage *logo = [[UIImage imageNamed:@"logo"]imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];

    UIBarButtonItem *item = [[UIBarButtonItem alloc]initWithImage:logo style:UIBarButtonItemStylePlain target:self action:nil];
    self.navigationItem.leftBarButtonItem = item;

You can even try with your current code by setting the UIImageRenderingModeAlwaysOriginal.
