用这个代码：

   UITextField *searchField = [self.searchBar valueForKey:@"_searchField"];
    [searchField setBackground:[UIImage imageNamed:@"searchfield_bg"]];

    [self.searchBar setTintColor:[UIColor blackColor]];
    UIImage *searchimg = [UIImage imageNamed:@"search_panel.png"];

    for (UIView *subview in self.searchBar.subviews) {
        if ([subview isKindOfClass:NSClassFromString(@"UISearchBarBackground")]) {
            UIView *bg = [[UIView alloc] initWithFrame:subview.frame];
            bg.backgroundColor = [UIColor colorWithPatternImage:searchimg];
            [self.searchBar insertSubview:bg aboveSubview:subview];
            [subview removeFromSuperview];
            [bg release];
            break;
        }
    }

我是用这个代码实现了这样的效果：你只要改一下颜色就行了。

最终效果是这样的
