可惡的UI非要搞一個和系統的UISearchBar的不一樣的效果，但是系統自帶的用實現不了效果，就自能自定義了。

把一個UISearchBar放到UINavigationBar上。並且還要有搜尋的結果在整個頁面上。。。

先看看效果圖

HZSearchBar

自定義searcher，完全模仿系統樣式

選擇遵循協議

1. CustomsearchResultsUpdater

   及時篩選代理同系統的searchResultsUpdater代理一樣的用法。

2. CustomSearchBarDataSouce
   設定資料來源

   // 設定顯示列的內容
   -(NSInteger)searchBarNumberOfRowInSection;\
   // 設定顯示沒行的內容
    
   
   -(NSString *)CustomSearchBar:(CustomSearchBar *)searchBar titleForRowAtIndexPath:(NSIndexPath *)indexPath;

   設定每行顯示的圖片

   // 每行圖片
   -(NSString *)CustomSearchBar:(CustomSearchBar *)searchBar imageNameForRowAtIndexPath:(NSIndexPath *)indexPath;

3. CustomSearchBarDelegate
   設定點選效果和監聽取消按鈕動作

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

新增HZSearchBar（以新增到導航欄為例）

    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

/**第一步根據輸入的字元檢索 必須實現*/
-(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];
    }
}
// 設定顯示列的內容
-(NSInteger)searchBarNumberOfRowInSection {
    return self.resultFileterArry.count;
}
// 設定顯示沒行的內容
-(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";
}
