最近开发一个关于社交的App需要获取通讯录的信息,由于项目由iOS9开始兼容，所以使用的时候iOS9以后苹果新推出的框架<Contacts/Contacts.h>
获取通讯录信息列表
1.获取权限
CNAuthorizationStatus status = [CNContactStore authorizationStatusForEntityType:CNEntityTypeContacts];
if (status == CNAuthorizationStatusNotDetermined) {
CNContactStore *contactStore = [[CNContactStore alloc]init];
[contactStore requestAccessForEntityType:CNEntityTypeContacts completionHandler:^(BOOL granted, NSError * _Nullable error) {
if (!granted) {
NSLog(@"授权失败");
}else{
NSLog(@"成功授权");
[self getContactInfo]; //读取数据
}
}];
}else if (status == CNAuthorizationStatusRestricted){
NSLog(@"用户拒绝授权");
}else if (status == CNAuthorizationStatusAuthorized){//已经授权
[self getContactInfo];//读取数据
}
2.读取数据
NSArray *keysToFetch = @[CNContactGivenNameKey,CNContactFamilyNameKey,CNContactPhoneNumbersKey];
//一个联系人可能存在多个电话和昵称
CNContactFetchRequest *fetchRequest = [[CNContactFetchRequest alloc]initWithKeysToFetch:keysToFetch];
CNContactStore *store = [CNContactStore new];
[store enumerateContactsWithFetchRequest:fetchRequest error:nil usingBlock:^(CNContact * _Nonnull contact, BOOL * _Nonnull stop) {
ContacterModel *model = [ContacterModel new];
NSString *giveName = contact.givenName;
NSString *familyName = contact.familyName;
//拼接姓名
NSString *nameStr = [NSString stringWithFormat:@"%@%@",familyName,giveName];
model.name = nameStr;
NSArray *phoneNumbers = contact.phoneNumbers;
for (CNLabeledValue *labelValue in phoneNumbers) {
//遍历一个人名下的多个电话号码
CNPhoneNumber *phoneNumber = labelValue.value;
NSString *string = phoneNumber.stringValue;
//去除特殊字符
string = [string stringByReplacingOccurrencesOfString:@"+86" withString:@""];
string = [string stringByReplacingOccurrencesOfString:@"-" withString:@""];
string = [string stringByReplacingOccurrencesOfString:@"(" withString:@""];
string = [string stringByReplacingOccurrencesOfString:@")" withString:@""];
string = [string stringByReplacingOccurrencesOfString:@" " withString:@""];
[model.numberArray addObject:string];
}
if (![model.name isEqualToString:@""] && model.numberArray.count >0
) {
[self.dataArray addObject:model];
}
}];
3.数据排序分组
self.sortedDic = [NSMutableDictionary dictionary];
[self.dataArray enumerateObjectsUsingBlock:^(id _Nonnull obj, NSUInteger idx, BOOL * _Nonnull stop) {
ContacterModel* model = (ContacterModel *)obj;
NSString *nameIndex = model.nameIndex;
if (!self.sortedDic[nameIndex]) {
//如果不存在这个字段,则创建
[self.sortedDic setValue:[NSMutableArray array] forKey:nameIndex];
}
[self.sortedDic[nameIndex] addObject:model];
}];
//将字典中的key排序:A-Z
self.keyArray = [[_sortedDic allKeys] sortedArrayUsingSelector:@selector(compare:)];
关于联系人我使用了一个模型来定义 其中有一个属性是：@property(nonatomic,copy)NSString *nameIndex;
这个属性定义的是联系人名称拼音的首字母
获取姓名拼音的首字母
+(NSString*)getFistLetterFromString:(NSString*)aString{
if (!aString || [aString isEqualToString:@""]) {
return @"#";
}
NSMutableString *mutableString = [NSMutableString stringWithString:aString];
CFStringTransform((CFMutableStringRef)mutableString, NULL, kCFStringTransformMandarinLatin, false);//转换为拼音
CFStringTransform((CFMutableStringRef)mutableString, NULL, kCFStringTransformStripDiacritics, false);//去除音标
NSString *pinyinString = [mutableString uppercaseString];
//这里可以考虑多音字的处理(暂未实现)
NSString *firstStr = [pinyinString substringToIndex:1];
//判断姓名首位是否为大写字母
NSString *regxA = @"^[A-Z]$";
NSPredicate *preA = [NSPredicate predicateWithFormat:@"SELF MATCHES %@",regxA];
return [preA evaluateWithObject:firstStr] ? firstStr : @"#";//如果首位不是大写字母开头就设置为#
}
备注
其中获取名字的首字母和数据的分组排序是知识点，部分Api使用较少，想要深入理解的请自行百度
