I've been developing an iOS app and have been having issues with using an image as the left bar button item in the navigation bar. I have attempted this in the following ways: 

UIImage *backButtonImage = [UIImage imageNamed:@"backbuttonCB"];
CGRect buttonFrame = CGRectMake(0, 0, backButtonImage.size.width, backButtonImage.size.height);
UIButton *backButton = [[UIButton alloc] initWithFrame:buttonFrame];
[backButton setImage:backButtonImage forState:UIControlStateNormal];
UIBarButtonItem *backBarButtonItem= [[UIBarButtonItem alloc] initWithCustomView: backButton];
self.navigationItem.leftBarButtonItem = backBarButtonItem;

The bar button never seems to display while running the app.

I then proceeded to try this other method as follows.

self.navigationItem.leftBarButtonItem = [[UIBarButtonItem alloc] initWithImage:[UIImage imageNamed:@"backbuttonCB"] style:UIBarButtonItemStylePlain target:nil action:@selector(methodname)];

This method actually worked. However, the image displayed was tinted blue and did not look like it was meant to. Changing the tint colour of this image did not help.

Any idea how I can solve this problem?

EDIT: More information, if it helps. This is the first view in the navigation stack. The navigation stack is displayed modally i.e. there is a previous view controller and there is a modal segue between the previous view controller and the navigation controller. This is the first view in the navigation stack.

EDIT: THE PROBLEM IS FIXED. I think it was a bug in xcode because when I restarted xcode and tested it with an actual device instead of the emulator, it worked fine. However, still doesn't seem to work on an emulator.

Try setting your leftBarButtonItem this way. While presenting modally it doesn't shows up.

self.navigationController?.navigationBar.topItem.leftBarButtonItem =
