Any idea why the custom nav bar back button image isn't displaying with this code?

Any idea why the custom nav bar back button image isn't displaying with this code?

instead of showing the uiimage it's showing the "< Back" default iOS button in text only

    [self.navigationController setNavigationBarHidden:NO animated:NO];

self.navigationItem.backBarButtonItem = [[UIBarButtonItem alloc] initWithImage:[UIImage imageNamed:@"freccia.png"] landscapeImagePhone:nil style:UIBarButtonItemStylePlain target:nil action:@selector(backBtnPress)];

could it be this parameter? UIBarButtonItemStylePlain

thanks

use this code: 

UIImage *imageBack = [UIImage imageNamed:@"yourImage.png"];
UIButton *btnBack = [UIButton buttonWithType:UIButtonTypeCustom];
btnBack.bounds = CGRectMake(0, 0, imageBack.size.width, imageBack.size.height);
[btnBack setBackgroundImage:imageBack forState:UIControlStateNormal];
[btnBack addTarget:self action:@selector(back) forControlEvents:UIControlEventTouchUpInside];
UIBarButtonItem *barButtonBack = [[UIBarButtonItem alloc] initWithCustomView:btnBack];

self.navigationItem.hidesBackButton = YES;
self.navigationItem.leftBarButtonItem = barButtonBack;

-(void)back {
[self.navigationController popViewControllerAnimated:YES];

}

you can solve this problem by two ways 1. use leftBarButtonItem instead of backBarButtonItem 2. try the below code

  self.navigationItem.backBarButtonItem =[[UIBarButtonItem alloc] initWithTitle:@" " style:UIBarButtonItemStylePlain target:nil action:nil];

You usually set the back button in the parent view controller. However, it might just be easier to use leftBarButtonItem instead of backBarButtonItem.
