Question

I have a navigation view controller with root view controller where I set the look of the navigation bar. It looks like this:

UIImage *navBarImage = [UIImage imageNamed:@"GreyUp.png"];
[[UINavigationBar appearance] setBackgroundImage:navBarImage
                                       forBarMetrics:UIBarMetricsDefault];

This thing though, changes the navBar appearance for all the following view controllers, which I would not like. I would like one navBar for root view and another one – for a different view. How can this be achieved?

Answer 1

Yes it can be achived use this in view will appear

[self.navigationController.navigationBar setBackgroundImage:[UIImage imageNamed:@"navBar.png"] forBarMetrics:UIBarMetricsDefault];

// for cutom back button

UIButton*    btnBack= [Utils createButtonWithTarget:self selector:@selector(btnBackClicked) frame:CGRectMake(0,5, 100, 40) bgimageName:@"tab_back.png" tag:0];//My method use yours
        self.navigationItem.leftBarButtonItem=[[UIBarButtonItem alloc] initWithCustomView:btnBack];
      //use btnBack ref to change font title title color etc

My Utils class code to create button

+ (UIButton *)createButtonWithTarget:(id)target
                            selector:(SEL)selector
                               frame:(CGRect)frame
                         bgimageName:(NSString *)imageName
                                 tag:(NSInteger)aTag{
    UIButton *button = [[UIButton buttonWithType:UIButtonTypeCustom] retain];
    button.frame = frame;
    [button setBackgroundImage:[UIImage imageNamed:imageName] forState:UIControlStateNormal];   
    [button addTarget:target action:selector forControlEvents:UIControlEventTouchUpInside];
    // in case the parent view draws with a custom color or gradient, use a transparent color
    button.backgroundColor = [UIColor clearColor];
    button.showsTouchWhenHighlighted = YES;
    button.tag = aTag;
    return [button autorelease];
}
