For change all UIBarButtonItems color in your app, set the tintColor property on the application's window in the AppDelegate. such like,

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    self.window.tintColor = [UIColor blueColor]; // or set color as you want.
    return YES;
}

Answer 3

You cannot change a backBarButtonItem 's colour but you can change its tint. Try adding the following to your App Delegate: [[UIBarButtonItem appearance] setTintColour:pinkColour]

Be careful, this will tint ALL of your bar buttons pink.

Try this for customized back button

UIView *backBtnView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 70, 40)];
backBtnView.backgroundColor = [UIColor clearColor];
UIButton *backBtn=[UIButton buttonWithType:UIButtonTypeCustom];
[backBtn setBackgroundColor:[UIColor clearColor]];
[backBtn setImage:[UIImage imageNamed:@"back.png"] forState:UIControlStateNormal];
[backBtn addTarget:self action:@selector(backBtnClicked) forControlEvents:UIControlEventTouchUpInside];
[backBtn setFrame:CGRectMake(5, 5, 57, 30)];
[backBtnView addSubview:backBtn];
self.navigationItem.leftBarButtonItem=[[UIBarButtonItem alloc]initWithCustomView:backBtnView];
