Can't set titleView in the center of navigation bar because back button

UINavigationBar automatically centers its titleView as long as there is enough room. If the title isn't centered that means that the title view is too wide to be centered, and if you set the backgroundColor if your UIImageView you'll see that's exactly what is happening.

The title view is too wide because that navigation bar will automatically resize the title to hold its content, using -sizeThatFits:. This means that your title view will always be resized to the size of your image.

Two possible fixes:

1. The image you're using is way too big. Use a properly sized 44x44 pt image with 2x and 3x versions.

2. Wrap UIImageView inside of a regular UIView to avoid resizing.

Example:

UIImageView* imageView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"test.jpeg"]];
imageView.contentMode = UIViewContentModeScaleAspectFit;

UIView* titleView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 44, 44)];
imageView.frame = titleView.bounds;
[titleView addSubview:imageView];

self.navigationItem.titleView = titleView;

An example in Swift 3 version of Darren's second way:

let imageView = UIImageView(image: UIImage(named: "test"))
    imageView.contentMode = UIViewContentMode.scaleAspectFit
let titleView = UIView(frame: CGRect(x: 0, y: 0, width: 44, height: 44))
    imageView.frame = titleView.bounds
    titleView.addSubview(imageView)

self.navigationItem.titleView = titleView

I suggest you Override the function - (void)setFrame:(CGRect)fram like this:

- (void)setFrame:(CGRect)frame  { 

    [super setFrame:frame]; //systom function

    self.center = CGPointMake(self.superview.center.x, self.center.y);   //rewrite function 

}

so that the titleView.center always the right location

Don't use titleView.

Just add your image to navigationController.navigationBar

CGRect myImageS = CGRectMake(0, 0, 44, 44);
UIImageView *logo = [[UIImageView alloc] initWithFrame:myImageS];
[logo setImage:[UIImage imageNamed:@"color.png"]];
logo.contentMode = UIViewContentModeScaleAspectFit;
logo.center = CGPointMake(self.navigationController.navigationBar.width / 2.0, self.navigationController.navigationBar.height / 2.0);
logo.autoresizingMask = UIViewAutoresizingFlexibleLeftMargin | UIViewAutoresizingFlexibleRightMargin | UIViewAutoresizingFlexibleTopMargin | UIViewAutoresizingFlexibleBottomMargin;
[self.navigationController.navigationBar addSubview:logo];

Qun Li's worked perfectly for me. Here's the swift 2.3 code:

override var frame: CGRect {
    set(newValue) {
        super.frame = newValue

        if let superview = self.superview {
            self.center = CGPoint(x: superview.center.x, y: self.center.y)
        }
    }

    get {
        return super.frame
    }
}
