@implementation UINavigationBar (UINavigationBarCategory)

- (void)drawRect:(CGRect)rect {
    //颜色填充
    //UIColor *color = [UIColor greenColor];
    //CGContextRef context = UIGraphicsGetCurrentContext();
    //CGContextSetFillColor(context, CGColorGetComponents( [color CGColor]));
    //CGContextFillRect(context, rect);
    //self.tintColor = color;
    //图片填充
    UIColor *color = [UIColor colorWithRed:46.0f/255.0f green:87.0f/255.0f blue:29.0f/255.0f alpha:1.0f];
    UIImage *img    = [UIImage imageNamed: @"button.png"];
    [img drawInRect:CGRectMake(0, 0, self.frame.size.width, self.frame.size.height)];
    self.tintColor = color;
