iOS 10开始，读取通讯录需要添加隐私设置，不然会造成程序崩溃。
<key>NSContactsUsageDescription</key>
<string>客户端需要访问您的通讯录</string>
写两个读取通信录得工具类，一个是判断是否拥有读取通讯录权限的，一个是用来获取通讯录的

更新 获取通讯录的一个坑
获取通讯录中用户全名的时候, 出现一个问题, 部分手机获取通讯录不全. 有一部分用户的手机号获取不到. 而且测试提出问题, 开发这里也无法复现.
现在分析问题发现, 任何客服端无法复现的bug, 都是因为没有找到问题根本的原因. 当然了, 如果找到了问题的根本原因, 可以完美复现bug了, 问题也就解决百分之八十了.
然后事实是测试人员发现bug就兴奋的提到bugfree, 根本不会给你总结bug复现规律的. 所以一切还得靠自己.
问题描述: 客户端读取本地通讯录, 读取后填充到页面显示. 发现部分测试机总有几个手机号读取不到. 比如王小明的手机号读取不到. 然后我尝试添加王小明到我的手机通讯录上, 可以读取到.
误区: 开始一直以为是代码中某些逻辑过滤掉了 某些手机号码. 所以查了好久也没有查到问题, 而且如上所说, 如果是过滤掉的, 那应该在其他手机可以复现, 结果并没有复现.
问题原因: 代码使用了 CNContactStore 方法获取通讯录(ios9+), 代码如下:
[store enumerateContactsWithFetchRequest:request error:nil usingBlock:^(CNContact * _Nonnull contact,BOOL * _Nonnull stop) {
// 获取联系人全名
NSString *name = [CNContactFormatter stringFromContact:contact style:CNContactFormatterStyleFullName];
// 获取一个人的所有电话号码
NSArray *phones = contact.phoneNumbers;
for (CNLabeledValue *labelValue in phones) {
CNPhoneNumber *phoneNumber = labelValue.value;
NSString *mobile = [self removeSpecialSubString:phoneNumber.stringValue];
NSDictionary *addressDic = [NSDictionary dictionary];
addressDic = @{@"num":mobile,@"name":name};
[addressBookArr addObject:addressDic];
}
}];
注意代码中, 获取用户全名, 我使用了NSString *name = [CNContactFormatter stringFromContact:contact style:CNContactFormatterStyleFullName];方法, 而该方法有一个问题是, 当通讯录中存在一个用户名为空的记录时, 全名会变成nil, 使得遍历过程中断(但是不会使程序崩溃). 中断后, 未遍历到的用户便成了"丢失人口".
发现这个原因后, 复现了bug, 更加坚信这是问题的原因. 我在自己手机通讯录中添加一条用户名为空的记录(通讯录中添加一个手机号, 然后不添加名字就保存). 然后再在通讯录中添加几个正常的记录, 再读取通讯录的过程中发现, 在用户名为空的记录后边添加的所有记录都读取不到. 很有规律, 猜测ios遍历通讯录是按照通讯录的添加时间的顺序, 而非人名的首字母.
解决方法: 更改获取通讯录全名的方法:
// 获取联系人全名
//NSString *name = [CNContactFormatter stringFromContact:contact style:CNContactFormatterStyleFullName];
//20180515说明:不再使用CNContactFormatterStyleFullName获取全名,这种情况下, 如果通讯录中存在只有号码没有名字的情况,会被(null)错误终止遍历, 导致通讯录读取不全.
NSString * givenName = contact.givenName;
NSString * familyName = contact.familyName;
NSLog(@"%@--%@", givenName, familyName);
NSString *name = [NSString stringWithFormat:@"%@%@",familyName, givenName];
完美!!
