iOS自定义UISearchBar，简单、方便、好用

可恶的UI非要搞一个和系统的UISearchBar的不一样的效果，但是系统自带的用实现不了效果，就自能自定义了。

把一个UISearchBar放到UINavigationBar上。并且还要有搜索的结果在整个页面上。。。

先看看效果图

HZSearchBar

自定义searcher，完全模仿系统样式

选择遵循协议

1. CustomsearchResultsUpdater

   及时筛选代理同系统的searchResultsUpdater代理一样的用法。

2. CustomSearchBarDataSouce
   设置数据源

   // 设置显示列的内容-(NSInteger)searchBarNumberOfRowInSection;\// 设置显示没行的内容-(NSString *)CustomSearchBar:(CustomSearchBar *)searchBar titleForRowAtIndexPath:(NSIndexPath *)indexPath;

   设置每行显示的图片

   // 每行图片-(NSString *)CustomSearchBar:(CustomSearchBar *)searchBar imageNameForRowAtIndexPath:(NSIndexPath *)indexPath;

3. CustomSearchBarDelegate
   设置点击效果和监听取消按钮动作

   // 点击每一行的效果- (void)CustomSearchBar:(CustomSearchBar *)searchBar didSelectRowAtIndexPath:(NSIndexPath *)indexPath;-(void)CustomSearchBar:(CustomSearchBar *)searchBar cancleButton:(UIButton *)sender;

添加HZSearchBar（以添加到导航栏为例）

    self.customSearchBar = [CustomSearchBar show:CGPointMake(0, 0) andHeight:SEMHEIGHT];    self.customSearchBar.searchResultsUpdater = self;    self.customSearchBar.DataSource = self;    self.customSearchBar.delegate = self;    [self.navigationController.view insertSubview:self.customSearchBar aboveSubview:self.navigationController.navigationBar];

代理的使用

/**第一步根据输入的字符检索 必须实现*/-(void)CustomSearch:(CustomSearchBar *)searchBar inputText:(NSString *)inputText {    [self.resultFileterArry removeAllObjects];    NSPredicate * predicate = [NSPredicate predicateWithFormat:@"SELF CONTAINS %@",inputText];    NSArray * arry = [self.myData filteredArrayUsingPredicate:predicate];    for (NSString * taxChat in arry) {        [self.resultFileterArry addObject:taxChat];    }}// 设置显示列的内容-(NSInteger)searchBarNumberOfRowInSection {    return self.resultFileterArry.count;}// 设置显示没行的内容-(NSString *)CustomSearchBar:(CustomSearchBar *)menu titleForRowAtIndexPath:(NSIndexPath *)indexPath {    return self.resultFileterArry[indexPath.row];}- (void)CustomSearchBar:(CustomSearchBar *)segment didSelectRowAtIndexPath:(NSIndexPath *)indexPath {    NSLog(@"---->>>>>>>>>%ld",indexPath.row);}-(void)CustomSearchBar:(CustomSearchBar *)segment cancleButton:(UIButton *)sender {}-(NSString *)CustomSearchBar:(CustomSearchBar *)searchBar imageNameForRowAtIndexPath:(NSIndexPath *)indexPath {    return @"Search_noraml";}
