iOS 通讯录二级列表实现

因为公司的需求，要完成一个全新的通讯录列表。参考了网上一些demo，自己修改也先写了一个demo。

效果图：

插入以及删除数据代码

#pragma mark - 展开（收起）子节点

- (void)deleteData:(NSMutableArray *)array {
    for (int i = 0; i<array.count; i++) {
        contact *model = [array objectAtIndex:i];
        if (model.parents) {
            [self deleteData:model.parents];
        }
        [searchResults removeObject:model];
    }
}


- (void)insertData:(NSMutableArray *)array {
    for (int i = 0; i<array.count; i++) {
        contact *model = [array objectAtIndex:i];
        self.rowCount++;
        [searchResults insertObject:model atIndex:self.rowCount];
        if (model.parents && model.open) {
            [self insertData:model.parents];
        }
    }
}


- (void)deleteData:(NSMutableArray *)array didSelect:(NSInteger)section{
    NSMutableArray * delete = [NSMutableArray new];
    [delete addObjectsFromArray:self.countArray[section]];
    for (int i = 0; i<array.count; i++) {
        
        contact *model = [array objectAtIndex:i];
        if (model.parents) {
            [self deleteData:model.parents didSelect:section];
        }
        [delete removeObject:model];
    }
    [self.countArray replaceObjectAtIndex:section withObject:delete];
}


- (void)insertData:(NSMutableArray *)array didSelect:(NSInteger)section{
    NSMutableArray * insert = [NSMutableArray new];
    [insert addObjectsFromArray:self.countArray[section]];
    for (int i = 0; i<array.count; i++) {
        contact *model = [array objectAtIndex:i];
        self.rowCount++;
        [insert insertObject:model atIndex:self.rowCount];
        if (model.parents && model.open) {
            [self insertData:model.parents didSelect:section];
        }
    }
    [self.countArray replaceObjectAtIndex:section withObject:insert];
}

实现模糊搜索

// 联系人搜索，可实现汉字搜索，汉语拼音搜索和拼音首字母搜索，
// 输入联系人名称，进行搜索， 返回搜索结果searchResults
- (void)searchBar:(UISearchBar *)searchBar textDidChange:(NSString *)searchText
{
    searchResults = [[NSMutableArray alloc]init];
    if (contactsSearchBar.text.length>0&&![ChineseInclude isIncludeChineseInString:contactsSearchBar.text]) {
        for (NSArray *section in self.countArray) {
            for (contact *contact in section)
            {
                if ([ChineseInclude isIncludeChineseInString:contact.stuName]) {
                    NSString *tempPinYinStr = [PinYinForObjc chineseConvertToPinYin:contact.stuName];
                    NSRange titleResult=[tempPinYinStr rangeOfString:contactsSearchBar.text options:NSCaseInsensitiveSearch];
                    
                    if (titleResult.length>0) {
                        [searchResults addObject:contact];
                    }
                    else {
                        NSString *tempPinYinHeadStr = [PinYinForObjc chineseConvertToPinYinHead:contact.stuName];
                        NSRange titleHeadResult=[tempPinYinHeadStr rangeOfString:contactsSearchBar.text options:NSCaseInsensitiveSearch];
                        if (titleHeadResult.length>0) {
                            [searchResults  addObject:contact];
                        }
                    }
                    NSString *tempPinYinHeadStr = [PinYinForObjc chineseConvertToPinYinHead:contact.stuName];
                    NSRange titleHeadResult=[tempPinYinHeadStr rangeOfString:contactsSearchBar.text options:NSCaseInsensitiveSearch];
                }
                else {
                    NSRange titleResult=[contact.stuName rangeOfString:contactsSearchBar.text options:NSCaseInsensitiveSearch];
                    if (titleResult.length>0) {
                        [searchResults  addObject:contact];
                    }
                }
            }
        }
    } else if (contactsSearchBar.text.length>0&&[ChineseInclude isIncludeChineseInString:contactsSearchBar.text]) {
        
        for (NSArray *section in self.countArray) {
            for (contact *contact in section)
            {
                NSString *tempStr = contact.stuName;
                NSRange titleResult=[tempStr rangeOfString:contactsSearchBar.text options:NSCaseInsensitiveSearch];
                if (titleResult.length>0) {
                    [searchResults addObject:contact];
                }
                
            }
        }
    }
}
