Question

我添加了UISearchBar作为我的表格标题，其中包含以下代码。

searchBar = [[UISearchBar alloc] initWithFrame:self.tableView.bounds];
searchBar.tintColor = [UIColor colorWithWhite:185.0/255 alpha:1.0];
[searchBar sizeToFit];
self.tableView.tableHeaderView = searchBar;

然后我将UISearchDisplayController设置如下。

searchDisplayController = [[UISearchDisplayController alloc] initWithSearchBar:searchBar contentsController:self];
[searchDisplayController setDelegate:self];
[searchDisplayController setSearchResultsDataSource:self];

除了UISearchDisplayController在搜索栏上方添加了蓝色（ish）边框外，所有功能都按照我的意愿运行 - 此栏无法识别我在搜索栏上设置的tintColor。< / p>

是否可以更改此栏的颜色？这显然不是绝对至关重要的，但如果它像那样保持蓝色，那条线将永远让我感到烦恼！

边框似乎没有很好地改变Tint颜色，所以我的设计师坚持要求我们改变它。就像在搜索栏的底部添加1px视图一样简单：

现在在viewDidLoad中，我创建一个1px视图并将其放置在搜索栏的最底部。

#define SEARCHBAR_BORDER_TAG 1337
- (void) viewDidLoad{
    // Set a custom border on the bottom of the search bar, so it's not so harsh
    UISearchBar *searchBar = self.searchDisplayController.searchBar;
    UIView *bottomBorder = [[UIView alloc] initWithFrame:CGRectMake(0,searchBar.frame.size.height-1,searchBar.frame.size.width, 1)];
    [bottomBorder setBackgroundColor:[UIColor colorWithWhite:200.0f/255.f alpha:1.0f]];
    [bottomBorder setOpaque:YES];
    [bottomBorder setTag:SEARCHBAR_BORDER_TAG];
    [searchBar addSubview:bottomBorder];
    [bottomBorder release];
}

现在，当用户实际搜索时，我也将色调颜色转换回默认值，因为着色搜索栏也会将取消按钮颜色染成难看的颜色。如果你做类似的事情，下面的代码将隐藏/显示每个州的边框：

- (void)searchDisplayControllerWillBeginSearch:(UISearchDisplayController *)controller{
    [controller.searchBar setTintColor:nil];

    // Hide our custom border
    [[controller.searchBar viewWithTag:SEARCHBAR_BORDER_TAG] setHidden:YES];
}

- (void)searchDisplayControllerWillEndSearch:(UISearchDisplayController *)controller{
    [controller.searchBar setTintColor:[UIColor colorWithRed:238.0f/255.0f green:245.0f/255.0f blue:248.0f/255.0f alpha:1.0f]];
    //Show our custom border again
    [[controller.searchBar viewWithTag:SEARCHBAR_BORDER_TAG] setHidden:NO];
}

Answer 2

searchBar.searchBarStyle = UISearchBarStyleMinimal;

Answer 3

试试这个：

searchBar.clipsToBounds = YES;
