读取用户通讯录的联系人信息

最近项目中用到上传用户通讯录的功能，做的过程中也遇到了一些问题，包括授权、中英文首字母排序、中英文输入字母搜索匹配等。
这里读取包括读取联系人的邮箱、公司、职位、备注、家乡。

中英文排序和搜索如何实现，我写了一个demo放在了github上。

1.iOS6之后读取用户通讯录是必须经过用户授权的，只会授权一次，不管你是允许还是不允许，以后想要在更改用户通讯录的权限，都只能在系统设置里修改。

2.做的过程中还发现其实如果你的读取通讯录的功能做在app内部的网页里，是可以不经用户授权直接跨过系统权限读取，也是可以成功的，H5页面跟app客户端进行交互，调用Native code(网页跟客户端的交互，如果有时间也是想单独总结出一篇，总之就是精力不够啊😂)

前面好像讲了一堆废话，好吧，还是直接上代码吧。

self.dataArrayDic = [NSMutableArray arrayWithCapacity:0];
ABAddressBookRef addressBook ;

addressBook = ABAddressBookCreateWithOptions(NULL, NULL);
dispatch_semaphore_t sema = dispatch_semaphore_create(0);
ABAddressBookRequestAccessWithCompletion(addressBook, ^(bool granted, CFErrorRef error)                                                     {
    dispatch_semaphore_signal(sema);
});
dispatch_semaphore_wait(sema, DISPATCH_TIME_FOREVER);
//取得本地所有联系人记录
CFArrayRef results = ABAddressBookCopyArrayOfAllPeople(addressBook);
for(int i = 0; i < CFArrayGetCount(results); i++)
{
    NSMutableDictionary *dicInfoLocal = [NSMutableDictionary dictionaryWithCapacity:0];
    ABRecordRef person = CFArrayGetValueAtIndex(results, i);
    ABMultiValueRef tmlphone =  ABRecordCopyValue(person, kABPersonPhoneProperty);
    NSArray *telphone = (__bridge NSArray*)ABMultiValueCopyArrayOfAllValues(tmlphone);

    }
    if ([first isEqualToString:@" "] && [last isEqualToString:@" "] ) {
        if (telphone.count > 0) {
            first = telphone[0];
        }
    }
    [dicInfoLocal setObject:first forKey:@"first"];

    NSString *nickname = (__bridge NSString *)ABRecordCopyValue(person, kABPersonNicknameProperty);

    [dicInfoLocal setObject:extra forKey:@"extra"];

    NSString *department = (__bridge NSString *)ABRecordCopyValue(person, kABPersonDepartmentProperty);

    NSString *personModifyDate = (__bridge NSString *)ABRecordCopyValue(person, kABPersonModificationDateProperty);
    if (personModifyDate == nil) {
        personModifyDate = @"";
    }

    }
    CFRelease(streetTmp);

    [extra setObject:street forKey:@"street"];

    if ([first isEqualToString:@" "] == NO || [last isEqualToString:@" "] || (telphone.count > 0)) {
        [self.dataArrayDic addObject:dicInfoLocal];
    }
}
CFRelease(results);//new
CFRelease(addressBook);//new

希望帮到你，Best wishes！
