On navigating to any view in an app which has navigation controller implemented, it shows a back button to go to the previous view. Is there a way I can use custom image instead

    It almost works like a back button. With the exception of the transition animation (after the button is tapped and current view is popped off the navigation to the right).

    The right way is to make a category.

    @interface UINavigationBar (MyNavigationBar)  
    -(void)drawRect:(CGRect)rect; 
    @end
    
    @implementation UINavigationBar (MyNavigationBar)
    -(void)drawRect:(CGRect)rect { 
    UIImage *image = [UIImage imageNamed:@"....."];  
    [image drawInRect:CGRectMake(0, 0, self.frame.size.width, self.frame.size.height)];
