iOS8,遍历seachBar 得不到textfield了就意味着之前的方法通通不能用了.

  mySearchBar = [[UISearchBar alloc]initWithFrame:CGRectMake(5, 28, self.navView.width - 70, 30)];
    mySearchBar.delegate = self;
    mySearchBar.showsCancelButton = NO;
    mySearchBar.backgroundImage =  [ComponentFactory getCreateImageWithColor:[UIColor clearColor]];//    这个方法可以替换背景图
    mySearchBar.barStyle = UIBarStyleDefault;
    mySearchBar.backgroundColor = [UIColor getColor:@"#ededed"];
    [mySearchBar setSearchFieldBackgroundImage:[ComponentFactory getSearchBarBackgroundImageWithColor:[UIColor getColor:@"#ededed"]] forState:UIControlStateNormal];
    mySearchBar.layer.borderWidth = 0;
    mySearchBar.layer.cornerRadius =2;
    mySearchBar.layer.borderColor = [UIColor clearColor].CGColor;
    mySearchBar.autocorrectionType = UITextAutocorrectionTypeNo;
    mySearchBar.autocapitalizationType = UITextAutocapitalizationTypeNone;

+ (UIImage *)getSearchBarBackgroundImageWithColor:(UIColor *)color
{
    CGRect rect = CGRectMake(0.0f, 0.0f, 320.0f, 44.0f);
    UIGraphicsBeginImageContext(rect.size);
    CGContextRef context = UIGraphicsGetCurrentContext();
    CGContextSetFillColorWithColor(context, [color CGColor]);
    CGContextFillRect(context, rect);
    UIImage *theImage = UIGraphicsGetImageFromCurrentImageContext();
    UIGraphicsEndImageContext();
    
    return theImage;
}
