进入主题！！

全局变量：

{
  UISearchBar * _mySearchBar;//搜索框
  UITextField * _searchField;//输入框(搜索框的)
  NSMutableArray * _saerch_DataSource;//索引(A~Z)数组

  BOOL _isUsingSearchBar;//是否在使用搜索框
}

属性：

//负责进行数据分组的原生类
@property (nonatomic, strong)UILocalizedIndexedCollation * localizedCollation;

@property (nonatomic,strong) NSMutableArray * dataArray;//全部数据
@property (nonatomic, copy)NSArray * handleContactObjects;//真正数据源：存放处理过的数组

@property (nonatomic,strong) NSMutableArray *searchResultArr;//搜索的结果

获取 定义好的搜索框(_mySearchBar)的 输入框：_searchField

_searchField = [_mySearchBar valueForKey:@"_searchField"];

索引的使用：

/** 索引 */
self.matesTabV.sectionIndexColor = [UIColor colorWithRed:42.f/255.f green:170.f/255.f blue:255.f/255.f alpha:1.f];//改变索引的颜色：浅蓝色
self.matesTabV.sectionIndexBackgroundColor = [UIColor clearColor];//改变索引的背景颜色
self.matesTabV.sectionIndexTrackingBackgroundColor = [UIColor redColor];//改变索引选中时的背景颜色

//索引数组
_saerch_DataSource = [[NSMutableArray alloc] init] ;  //初始化索引数据
for(char c = 'A'; c <= 'Z'; c++ ) { //存放:`A`~`Z`
    [_saerch_DataSource addObject:[NSString stringWithFormat:@"%c",c]];
    if (c == 'Z') {
        [_saerch_DataSource addObject:[NSString stringWithFormat:@"#"] ];
    }
}


//实例化 分组的原生类
self.localizedCollation = [UILocalizedIndexedCollation currentCollation];

索引的代理设置：

//MARK:sectionIndex（UITableViewDataSource）
-(NSArray *)sectionIndexTitlesForTableView:(UITableView *)tableView { 
    return _saerch_DataSource;//返回索引数组：A~Z
}


-(NSInteger)tableView:(UITableView *)tableView sectionForSectionIndexTitle:(NSString *)title atIndex:(NSInteger)index { 
    //响应 点击索引时的委托方法（属于DataSource）

    if (_isUsingSearchBar == NO) { //非搜索状态
        NSInteger count = 0;
//    NSLog(@"点击的标题:%@---位置:%ld",title,(long)index);

        //MBProgressHUD 显示 标题的文字
        MBProgressHUD *hud = [MBProgressHUD showHUDAddedTo:self.view animated:YES];
        hud.mode = MBProgressHUDModeText;
        hud.label.font = [UIFont boldSystemFontOfSize:35.f];
        hud.label.text = [NSString stringWithFormat:@"%@ ",_saerch_DataSource[index]];
        hud.label.textAlignment = NSTextAlignmentCenter;
        hud.label.adjustsFontSizeToFitWidth = YES;
        hud.margin = 35.f;
        hud.offset = CGPointMake(0, 0.f);
        hud.removeFromSuperViewOnHide = YES;
        [hud hideAnimated:YES afterDelay:1.f];
        hud.userInteractionEnabled = NO; //可用户交互(self.view)
    
        for(NSString *character in _saerch_DataSource) {
            if([character isEqualToString:title]) {
                return count; //点击的位置
            }
            count ++;
        }
    }

     return 0;
}

效果：字体浅蓝色，选择时背景为红色！

对tableView的代理使用：

#pragma mark - UITableViewDataSource

//搜索框有文字时，只有 一个组(section)
-(NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
    if (_searchField.text.length > 0) { //搜索框有文字
        return 1;
    } else {
        return _saerch_DataSource.count;//self.handleContactObjects.count
    }
}

//搜索框有文字，返回 搜索到的数组
-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
    if (_searchField.text.length > 0) { //搜索框有文字
        return self.searchResultArr.count;
    } else {
        return ((NSArray *)self.handleContactObjects[section]).count;
    }
}


//在搜索框有文字时，使用搜索文字所产生的数组：self.searchResultArr
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {

    MateListTableViewCell * cell = [tableView cellForRowAtIndexPath:indexPath];
    if (!cell) {
        cell = [[MateListTableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:@"cell"];
    }

    if (_searchField.text.length > 0) {
        //搜索框有文字
        if (self.searchResultArr.count > 0) {
            cell.model = self.searchResultArr[indexPath.row];
        }
    
    } else {
        if (self.handleContactObjects.count > 0 && ((NSArray *)self.handleContactObjects[indexPath.section]).count > 0) {
            cell.model = ((NSArray *)self.handleContactObjects[indexPath.section])[indexPath.row];
        }

    }

    cell.selectionStyle = UITableViewCellSelectionStyleNone; //无选中色
    return cell;
}


//在使用搜索框、最终的数组为空时，隐藏 header视图（返回高度为：0）
-(CGFloat)tableView:(UITableView *)tableView heightForHeaderInSection:(NSInteger)section {
    if (_searchField.text.length > 0 ) { //在使用搜索
        return 0.f; 
    }

    if (self.handleContactObjects.count > 0 && ((NSArray *)self.handleContactObjects[section]).count == 0) {
        return 0.f; //最终的数组为空时
    }
    return SCREEN_WIDTH*60.f/750.f;
}
//设置header视图的标题
- (NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section {
    return _saerch_DataSource[section];
}

点击Cell，跳转到详情界面：

• 搜索框有文字，使用搜索产生的数组：self.searchResultArr
• 搜索框无文字，使用分好组的数组：self.handleContactObjects

---

#pragma mark - UITableViewDelegate
-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
    MateDetailInfoViewController * mateDetailInfoVC = [[MateDetailInfoViewController alloc] init];
    [self.navigationController pushViewController:mateDetailInfoVC animated:YES];

    if (_searchField.text.length > 0) { //搜索框有文字
        mateDetailInfoVC.mateCellModel = self.searchResultArr[indexPath.row];
    } else {
        mateDetailInfoVC.mateCellModel = ((NSArray *)self.handleContactObjects[indexPath.section])[indexPath.row];
    }

}

分组的使用：

self.dataArray = @[model,model2,model3,model4,model5,model6,model7,model8,model9,model10].mutableCopy;

self.handleContactObjects = [self getTheHandleContactObjects];//真正数据源：获取分好的数组

self.searchResultArr = @[].mutableCopy;//搜索的数组


[self.matesTabV reloadData];

获取分组后的数组：（真正数据源） 按文字的字母顺序放置在相应的“A~Z”(section)区间！

#pragma mark - localizedCollation Setter
-(NSArray*)getTheHandleContactObjects {
    //初始化数组返回的数组
    NSMutableArray * contacts = [NSMutableArray arrayWithCapacity:0];

    /**** 根据UILocalizedIndexedCollation的27个Title放入27个存储数据的数组 ****/
    for (NSInteger i = 0; i < self.localizedCollation.sectionTitles.count; i++) {
        [contacts addObject:[NSMutableArray arrayWithCapacity:0]];
    }


    //开始遍历联系人对象，进行分组（name方法）
    for (MateCellModel * model in self.dataArray) {
        NSInteger section = [self.localizedCollation sectionForObject:model collationStringSelector:@selector(name)]; //获取名字对应section
    
        [contacts[section] addObject:model];//根据索引在相应的数组上添加数据
    }


    //对每个同组的联系人进行排序
    for (NSInteger i = 0; i < self.localizedCollation.sectionTitles.count; i++) {
        //获取 需要排序的数组
        NSMutableArray * tempMutableArray = contacts[i];
    
        //通过nameObject的name进行排序，排序器排序
        NSSortDescriptor * sortDescriptor = [NSSortDescriptor sortDescriptorWithKey:@"name" ascending:true];
        [tempMutableArray sortUsingDescriptors:@[sortDescriptor]];
        contacts[i] = tempMutableArray;
    }

    //返回
    return [NSArray arrayWithArray:contacts];
}

搜索的使用：

    _mySearchBar.showsCancelButton = YES; //取消按钮(显示)
    _isUsingSearchBar = YES; //搜索框使用状态：YES

- (BOOL)includeChinese//判断是否含有汉字
{
    for(int i=0; i< [self length];i++)
    {
        int a =[self characterAtIndex:i];
        if( a >0x4e00&& a <0x9fff){
            return YES;
        }
    }
    return NO;
