1、首先获取本地通讯录

2、根据姓名和手机号实现搜索功能,当然拼音搜索也是支持的

1.1、今天在实现项目功能上需要获取本地的通讯录，然后在去自定义tableview显示通讯录信息，再然后就是实现搜索功能，在网上找了一圈都没合适的就自己动手开始写了。
1.2、获取到手机的通讯录相信大家都知道怎么搞，我这里是直接使用的前辈封装好的PPGetAddressBook再次感谢这些开源作者
1.3、额，逼逼两分钟让大家看看效果图吧

2.1、下面咱们还是直接看代码吧
创建tableview的搜索头。
_headView = [[UIView alloc]initWithFrame:CGRectMake(15, 0, SCREEN_WIDTH, 54)];
_headView.backgroundColor = [UIColor whiteColor];
_searchBar = [[UISearchBar alloc] init];
_searchBar.placeholder = @"搜索联系人";
_searchBar.delegate = self;
_searchBar.frame = CGRectMake(15,7,SCREEN_WIDTH - 30,40);
_searchBar.backgroundColor = BackGroundColcor;
_searchBar.backgroundImage = [UIImage new];
_searchBar.layer.cornerRadius = 3;
_searchBar.layer.masksToBounds = YES;
[_searchBar.layer setBorderColor:[UIColor whiteColor].CGColor];
[_headView addSubview:self.searchBar];

2.2、实现UISearchBar的代理方法
-(void)searchBar:(UISearchBar *)searchBar textDidChange:(NSString *)searchText{

if (searchText.length > 0) {
    self.isSearch = YES;

}else{
    
    self.isSearch = NO;
    [searchBar resignFirstResponder];

}


[self.searchArr removeAllObjects];

for (int i = 0; i<self.allPeopleArr.count; i++) {
    PPPersonModel *model = self.allPeopleArr[i];
    NSString *lowStr = [ChineseToPinyin pinyinFromChineseString:searchText withSpace:NO ];
    NSString *allStr =[ChineseToPinyin pinyinFromChineseString:model.name withSpace:NO ];
    //**********手机号模糊搜索*************//
    if (model.mobileArray.count == 1) {
        
        if ([model.mobileArray[0] rangeOfString:searchText].location != NSNotFound) {
            
            [self.searchArr addObject:model];

        }
        
    }else{
        
        for (int i= 0; i<model.mobileArray.count; i++) {
            if ([model.mobileArray[i] rangeOfString:searchText].location != NSNotFound) {
                [self.searchArr addObject:model];

            }

        }
    
    
    }
    
    //**********姓模糊搜索*************//
    self.searchKeyText = [NSString stringWithFormat:@"%c",[ChineseToPinyin sortSectionTitle:searchText]];
    BOOL isHas = [allStr isEqualToString:lowStr];
    BOOL isPY = false;
    if ( lowStr || lowStr.length != 0) {
        
        isPY = [allStr hasPrefix:lowStr];

    }
    if (isHas) {
        //这种情况是精确查找。
        LLAppLog(@"%@",model.name);
        [self.searchArr addObject:model];//讲搜索后的数据添加到数组中
        
    }else{

        if (isPY && !isHas) {
            //迷糊查找
            LLAppLog(@"----%@",model.name);
            [self.searchArr addObject:model];

        }
        
    }
    
}
[self.tableView reloadData];

}

写的不好，或者有问题的地方欢迎大家评论指出呀。。小弟是彩笔
虽然不够好，但是demo还是有的(https://github.com/HeQianLong/AddressSearch/tree/master)
