IOS开发代码分享之设置UISearchBar的背景颜色

今天用到UISearchBar，之前网上提供的方法已经不能有效的去除掉它的背景色了，修改背景色方法如下：

mySearchBar.backgroundColor = RGBACOLOR(249,249,249,1);
    mySearchBar.backgroundImage = [self imageWithColor:[UIColor clearColor] size:mySearchBar.bounds.size];

//取消searchbar背景色
- (UIImage *)imageWithColor:(UIColor *)color size:(CGSize)size
{
    CGRect rect = CGRectMake(0, 0, size.width, size.height);
    UIGraphicsBeginImageContext(rect.size);
    CGContextRef context = UIGraphicsGetCurrentContext();

    CGContextSetFillColorWithColor(context, [color CGColor]);
    CGContextFillRect(context, rect);

    UIImage *image = UIGraphicsGetImageFromCurrentImageContext();
    UIGraphicsEndImageContext();

    return image;
}
