自定义UISearchBar：试图摆脱搜索栏下方的1px黑线 [英] Customize UISearchBar: Trying to get rid of the 1px black line underneath the search bar

问题描述

我的问题已在标题中指明：我想摆脱 UISearchBar 底部绘制的黑线。有什么想法？

My question is already specified in the title: I would like to get rid of the black line drawn on the bottom of the UISearchBar. Any ideas?

这是我的意思的图像：

更新：

我认为该行是 UITableView 的 tableHeaderView 。我仍然不知道如何删除它。

I think that the line is part of the UITableView's tableHeaderView. I still don't know how to remove it.

推荐答案

我通过添加子视图修复此问题到 searchBar 的视图堆栈如下：

I fixed this by adding a subview to the searchBar's view stack like so:

CGRect rect = self.searchBar.frame;
UIView *lineView = [[UIView alloc]initWithFrame:CGRectMake(0, rect.size.height-2,rect.size.width, 2)];
lineView.backgroundColor = [UIColor whiteColor];
[self.searchBar addSubview:lineView];

此处， self.searchBar 是 UISearchBar 我的控制器类的指针。

Here, self.searchBar is an UISearchBar pointer of my controller class.
