//searchBar
- (UISearchBar *)searchBarInit
{if (!_searchBar) {_searchBar = [[UISearchBar alloc]initWithFrame:CGRectMake(0, 64, SCREEN_WIDTH, 40)];_searchBar.backgroundColor = [UIColor clearColor];_searchBar.delegate = self;_searchBar.placeholder = @"请输入目的地";_searchBar.showsCancelButton = NO;[self.view addSubview:_searchBar];}return _searchBar;
}

3、调用代理方法

#pragma mark - searchBar代理
- (BOOL)searchBarShouldBeginEditing:(UISearchBar *)searchBar
{searchBar.showsCancelButton = YES;if (!searchView) {searchView = [[FJSearchView alloc]init];[self.view addSubview:searchView];[searchView mas_makeConstraints:^(MASConstraintMaker *make) {make.left.right.bottom.mas_equalTo(self.view);make.top.mas_equalTo(searchBar.mas_bottom).offset(0);}];}else{searchView.hidden = NO;}return YES;
}- (BOOL)searchBarShouldEndEditing:(UISearchBar *)searchBar
{return YES;
}- (void)searchBarCancelButtonClicked:(UISearchBar *)searchBar __TVOS_PROHIBITED
{searchBar.showsCancelButton = NO;if (!searchView.isHidden) {
//        [searchView removeFromSuperview];searchView.hidden = YES;}[searchBar resignFirstResponder];[searchResultArray removeAllObjects];[searchView.resultTableView reloadData];
}- (void)searchBar:(UISearchBar *)searchBar textDidChange:(NSString *)searchText
{
    //option是百度搜索类的BMKSuggestionSearchOption，searcher是BMKSuggestionSearch
    option = [[BMKSuggestionSearchOption alloc] init];option.cityname = @"重庆市";option.keyword = searchText;[_searcher suggestionSearch:option];
}- (void)searchBarSearchButtonClicked:(UISearchBar *)searchBar
{option = [[BMKSuggestionSearchOption alloc] init];option.cityname = @"重庆市";option.keyword = searchBar.text;[_searcher suggestionSearch:option];[searchBar resignFirstResponder];
}

三、创建tableview展示结果

//tableview
- (UITableView *)resultTableViewInit
{if (!_resultTableView) {_resultTableView = [[UITableView alloc]initWithFrame:CGRectMake(0, 0, SCREEN_WIDTH, SCREEN_HEIGHT)];_resultTableView.delegate = self;_resultTableView.dataSource = self;[self addSubview:_resultTableView];[_resultTableView mas_makeConstraints:^(MASConstraintMaker *make) {make.left.right.bottom.top.mas_equalTo(self);}];}return _resultTableView;
}#pragma mark - tableView代理#pragma mark - tableView datasource
-(NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{return 1;
}-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{return _dataArray.count;
}-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{UITableViewCell *cell = [[UITableViewCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:@"resultCell"];
    //自定义的model存储搜索结果的地址名和坐标字段
    FJSearchResultModel *model = [[FJSearchResultModel alloc]init];for (int i = 0; i < _dataArray.count; i++) {if (i == indexPath.row) {model = _dataArray[i];cell.textLabel.text = model.name;}}return cell;
}

四、调用百度地图的搜索接口-最关键部分

//初始化搜索
- (void)setupSearcher
{//初始化检索对象_searcher =[[BMKSuggestionSearch alloc]init];_searcher.delegate = self;option = [[BMKSuggestionSearchOption alloc] init];option.cityname = @"重庆市";option.keyword  = @"";BOOL flag = [_searcher suggestionSearch:option];if(flag){NSLog(@"建议检索发送成功");}else{NSLog(@"建议检索发送失败");}
}

#pragma mark - 在线建议查询代理
//实现Delegate处理回调结果
- (void)onGetSuggestionResult:(BMKSuggestionSearch*)searcher result:(BMKSuggestionResult*)result errorCode:(BMKSearchErrorCode)error{if (error == BMK_SEARCH_NO_ERROR) {if (searchResultArray.count != 0) {[searchResultArray removeAllObjects];}//在此处理正常结果for (int i = 0; i < result.keyList.count; i++) {FJSearchResultModel *model = [[FJSearchResultModel alloc]init];model.name = result.keyList[i];CLLocationCoordinate2D coor;[result.ptList[i] getValue:&coor];model.kCoordinate = coor;[searchResultArray addObject:model];}searchView.dataArray = searchResultArray;[searchView.resultTableView reloadData];}else {NSLog(@"抱歉，未找到结果");}
}

-(void)viewWillDisappear:(BOOL)animated
{_searcher.delegate = nil;
}
