Answer 1

It may helpful for you
UIBarButtonItem *backBarButton = [[UIBarButtonItem alloc] initWithTitle:#"Back" style:UIBarButtonItemStyleDone target:self action:#selector(backAction:)];
self.navigationItem.leftBarButtonItem = backBarButton;

Answer 2

From the view controller (ViewController1) that is pushing the next view controller (ViewController2), you need to set the backBarButtonItem.
#implementation ViewController1
- (void)viewDidLoad
{
[super viewDidLoad];
self.navigationItem.backBarButtonItem = [[UIBarButtonItem alloc] initWithTitle:#"New Title" style:UIBarButtonItemStylePlain target:nil action:nil];
}

Answer 3

It's totally normal that you don't see any arrow in your back button. That's because you're creating a new bar button that you set its title and its style. But the style you've set for your bar button item won't give you what you wanted.
I suppose that you're using UINavigationController to navigate. If it's the case, you need to get a reference to navigationBar that UINavigationController displays on the screen. Then, you'll be able to change its color via tint color property. So,
[self.navigationController.navigationBar setTintColor:[UIColor redColor]];
would do what you want to achieve. Here is the image i obtained using the code i mentioned above.
If you're not using UINavigationController, the simplest solution is to provide an image for your back button which has already an arrow.

Answer 4

You should set backBarButtonItem instead of leftBarButtonItem. And remember to set it not in current view controller (where you wish it to be displayed) but in parent one (to which this button will return you).

Answer 5

Use this Code and
UIButton *backBtn = [UIButton buttonWithType:UIButtonTypeCustom];
UIImage *backBtnImage = [UIImage imageNamed:#"BackBtn.png"] ;
[backBtn setBackgroundImage:backBtnImage forState:UIControlStateNormal];
[backBtn addTarget:self action:#selector(goback) forControlEvents:UIControlEventTouchUpInside];
backBtn.frame = CGRectMake(0, 0, 54, 30);
UIBarButtonItem *backButton = [[UIBarButtonItem alloc] initWithCustomView:backBtn] ;
self.navigationItem.leftBarButtonItem = backButton;
and for going to back use this method .
-(void)goback
{
[self.navigationController popViewControllerAnimated:YES];
}

Answer 6

This worked for me
UIImage *image = [[UIImage imageNamed:#"btn_back.png"] imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];
UIBarButtonItem *button = [[UIBarButtonItem alloc] initWithImage:image style:UIBarButtonItemStylePlain target:self action:#selector(backAction:)];
self.navigationItem.leftBarButtonItem = button;
- (IBAction)backAction:(id)sender
{
MainMenuViewController *mainMenuViewController = [[MainMenuViewController alloc] init];
[self.navigationController pushViewController:mainMenuViewController animated:YES];
}
