You can achieve what you want by setting the <code>navigationItem.leftBarButtonItem</code> of the view controller that's being pushed to the custom bar button item with the look you want. Good Luck!

You can add a <code>UIImage</code> to the <code>UIButton</code>. And, then use it as a custom back button. Here's a quick example:

<pre><code>// Custom image
UIImage *backButtonImage = [UIImage imageNamed:@"button-background-image.png"];
UIButton *backButton = [UIButton buttonWithType:UIButtonTypeCustom];
[backButton setFrame:CGRectMake(0, 0, 100, 30)];
[backButton setBackgroundImage:backButtonImage forState:UIControlStateNormal];

// Custom title
[backButton setTitle:@"Back" forState:UIControlStateNormal];
[backButton setTitleColor:[UIColor redColor] forState:UIControlStateNormal];
[backButton addTarget:self action:@selector(barPayButtonPressed:) forControlEvents:UIControlEventTouchUpInside];
[backButton setShowsTouchWhenHighlighted:NO];

UIBarButtonItem *buttonOnBar =[[UIBarButtonItem alloc] initWithCustomView:backButton];
self.navigationItem.leftBarButtonItem = buttonOnBar;
</code></pre>

Note: You will loose the chevron (system-provided back arrow) which was introduced in iOS7. It goes as a title and chevron together presenting your previous view controller. 

Update:

You can also use <code>UIEdgeInsets</code> to resize your image intelligently. 

<pre><code>UIEdgeInsets edgeInsets = UIEdgeInsetsMake(0, 0, 15, 10); 
UIImage *backButtonImage = [[UIImage imageNamed:@"button-background-image.png"] resizableImageWithCapInsets:edgeInsets];
</code></pre>

Is it possible to change the back button on a UINavigationBar and change the title?

When I try to set the customView property, I get an image right next to the default button.

I use this code

<pre><code>self.navigationItem.backBarButtonItem = [[UIBarButtonItem alloc] initWithImage:backButtonImage landscapeImagePhone:nil style:UIBarButtonItemStylePlain target:nil action:nil];
</code></pre>

I want the title to be "Back" which is easy enough to do in Storyboard. But the problem is that no matter if I use code above or use customView property, the default back button remains.
