(原)iOS 用recursiveDescription打印View

今天要做一个搜索功能，用到UISearchBar 无奈背景太丑，就自定义了一个，首先用View私有方法打印一下searchBar的层次，

具体修改代码如下

        for (UIView *view in _topSerachBar.subviews)
        {    if ([view isKindOfClass:NSClassFromString(@"UIView")] && view.subviews.count > 0) {
            [[view.subviews objectAtIndex:0] removeFromSuperview];
            [[view.subviews objectAtIndex:0] setBackgroundColor:[UIColor redColor]];
            [[view.subviews objectAtIndex:1] setTitle:@"自定义"];
            break;
        }        }
    }
