Q:

iOs: How to change color of "more" back button when having more than 5 tabs

I have an application with 6 tabs, so the system automatically generates the first 4 tabs and a fifth tab called "Altro" ("More" in italian) that contains the previous fifth and sixth tab content.
This is ok. The problem is that i don't know how to change the color of the back button when going through the "altro" tab. Any advice?
Some screenshot for a better explanation of the problem:

A:

UIImage *buttonImage = [UIImage imageNamed:@"back_btn.png"];
UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
[button setImage:buttonImage forState:UIControlStateNormal];
button.frame = CGRectMake(0, 0, buttonImage.size.width/2, buttonImage.size.height/2);
[button addTarget:self action:@selector(backPressed) forControlEvents:UIControlEventTouchUpInside];
UIBarButtonItem *customBarItem = [[UIBarButtonItem alloc] initWithCustomView:button];
self.navigationItem.leftBarButtonItem = customBarItem;

Try this.......once
