UISearchBar:改变输入字段的背景颜色

Question

我正在尝试更改UISearchBar输入字段的背景颜色.这是您输入要搜索的文本的圆角视图,默认颜色为白色.我想把它改成灰色

我试过了:

for (UIView *subView in searchBar.subviews) {
    if ([subView isKindOfClass:NSClassFromString(@"UITextField")]) {
        UITextField *textField = (UITextField *)subView;
        [textField setBackgroundColor:[UIColor grayColor]];
    }

但它不起作用:(

我还尝试将图像视图插入TextField,但似乎圆角视图与TextField分开.那么,有什么线索吗？

    for(id field in subView.subviews){
        if ([field isKindOfClass:[UITextField class]]) {
            UITextField *textField = (UITextField *)field;
            [textField setBackgroundColor:[UIColor grayColor]];
        }
    }
}
