Navigation bar back button color
<p>I am unable to change the color of navigation bar back button. Any help? I customized the UINavigationBar class but I'm unable to change the back button color.</p>

<pre>UINavigationBar class code

#import 
#import "UINavigationBar.h"

@interface UINavigationBar ( Category )
{

}

.m file code

- (void) drawRect:(CGRect)rect 
{

    [[UIImage imageNamed:@"top.png"] drawInRect:rect];
    self.tintColor = [UIColor colorWithRed:38 green:65 blue:82 alpha:1];    
}</pre>

<p>I'm not able to change the color of the back button.</p>
