Address book group sorting, search

Proxy Settings for indexes:

/ / MARK: sectionIndex (UITableViewDataSource) - (NSArray *) sectionIndexTitlesForTableView tableView: (UITableView *) {return _saerch_DataSource; // return the index array: A~Z } -(NSInteger)tableView:(UITableView *)tableView sectionForSectionIndexTitle:(NSString *)title If (_isUsingSearchBar == NO) {// Non-search state NSInteger count = 0; / / NSLog (@ "click on the title: % @ - location: % ld", the title, (long) index); 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; // Self.view for(NSString *character in _saerch_DataSource) {if([character isEqualToString:title]) {return count; } count ++; } } return 0; }Copy the code

Effect: Light blue font with red background when selected!

For tableView proxies:

#pragma mark - UITableViewDataSource // There is only one group (section) - (NSInteger) numberOfSectionsInTableView tableView: (UITableView *) {if (_searchField. Text. Length > 0) { // Search box has text return 1; } else { return _saerch_DataSource.count; / / self. HandleContactObjects. Count}} / / search box with words, -(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {if (_searchField. Text. Length > 0) {/ / search box have return self. SearchResultArr. Count; } else { return ((NSArray *)self.handleContactObjects[section]).count; }} // When the search box has text, use the array generated by the search text: self.searchResultArr -(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { MateListTableViewCell * cell = [tableView cellForRowAtIndexPath:indexPath]; if (! cell) { cell = [[MateListTableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:@"cell"]; } the if (_searchField. Text. Length > 0) {/ / text search box with the if (self. SearchResultArr. Count > 0) {cell. The 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; Return cell; } // Hide the header view when the search box is used and the final array is empty (return height: 0) - (CGFloat) tableView: (UITableView *) tableView heightForHeaderInSection: (NSInteger) section {the if (_searchfield.text.length > 0) {// Return 0. F; } if (self.handleContactObjects.count > 0 && ((NSArray *)self.handleContactObjects[section]).count == 0) { return 0.f; } return SCREEN_WIDTH*60.f/750.f; } // set the header view title - (NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section {return _saerch_DataSource[section]; }Copy the code

Click Cell to jump to the details interface:

• The search box has text, using the array produced by the search: self.searchResultarr
• Search box, with no text, use a good set of array: 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) {/ / search box have text mateDetailInfoVC mateCellModel = self. SearchResultArr [indexPath. Row]; } else { mateDetailInfoVC.mateCellModel = ((NSArray *)self.handleContactObjects[indexPath.section])[indexPath.row]; }}Copy the code

Use of groups:

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];
Copy the code

Get the grouped array :(real data source) alphabetically placed in the corresponding “A to Z” section!

# pragma mark - localizedCollation Setter - (NSArray *) getTheHandleContactObjects {/ / initializes the array of the returned array NSMutableArray * contacts = [NSMutableArray arrayWithCapacity:0]; / * * * * according to UILocalizedIndexedCollation 27 Title in 27 * * * * / store data array for (NSInteger I = 0; i < self.localizedCollation.sectionTitles.count; i++) { [contacts addObject:[NSMutableArray arrayWithCapacity:0]]; } // Start traversing the contact object, For (MateCellModel * model in self.dataarray) {NSInteger section = [self.localizedCollation sectionForObject:model collationStringSelector:@selector(name)]; // Get the name corresponding to section [contacts[section] addObject:model]; For (NSInteger I = 0; NSInteger I = 0; i < self.localizedCollation.sectionTitles.count; I ++) {// Get the array to sort NSMutableArray * tempMutableArray = contacts[I]; // Sort by nameObject name, SortDescriptor NSSortDescriptor * sortDescriptor = [NSSortDescriptor sortDescriptorWithKey:@"name" ascending:true]; [tempMutableArray sortUsingDescriptors:@[sortDescriptor]]; contacts[i] = tempMutableArray; } // return [NSArray arrayWithArray:contacts]; }Copy the code
