列出带有电话号码的联系人

Question

我只想获取（在 iOS 中使用 Objective-C）有电话号码的联系人，但我该怎么做呢？我试图在下面的代码中形成谓词，但显然这不起作用。

contacts = [contactStore unifiedContactsMatchingPredicate:[NSPredicate predicateWithFormat:@"phoneNumbers <> nil"] keysToFetch:KEYS error:nil];

那么，这样做的正确方法是什么？感谢您的帮助！

使用以下方法并导入

#import <AddressBook/AddressBook.h>
#import <Contacts/Contacts.h> 


-(void)contactsDetailsFromPhoneContactBook{
    CNContactStore *store = [[CNContactStore alloc] init];
    [store requestAccessForEntityType:CNEntityTypeContacts completionHandler:^(BOOL granted, NSError * _Nullable error) {
        if (granted == YES) {
            //keys with fetching properties
            NSArray *keys = @[CNContactFamilyNameKey,CNContactGivenNameKey];
            NSString *containerId = store.defaultContainerIdentifier;
            NSPredicate *predicate = [CNContact predicateForContactsInContainerWithIdentifier:containerId];
            NSError *error;
            NSArray *cnContacts = [store unifiedContactsMatchingPredicate:predicate keysToFetch:keys error:&error];
            if (error) {
                NSLog(@"error fetching contacts %@", error);
            } else {
                NSString *fullName;
                NSString *firstName;
                NSString *lastName;
                for (CNContact *contact in cnContacts) {
                    // copy data to my custom Contacts class.
                    firstName = contact.givenName;
                    lastName = contact.familyName;
                    if (lastName == nil) {
                        fullName=[NSString stringWithFormat:@"%@",firstName];
                    }else if (firstName == nil){
                        fullName=[NSString stringWithFormat:@"%@",lastName];
                    }
                    else{
                        fullName=[NSString stringWithFormat:@"%@ %@",firstName,lastName];
                    }
                    [self.contactsArray addObject:fullName];

                    NSLog(@"working or not %@",self.contactsArray);
                }

            }
        }
    }];
}

Answer 3

无法过滤掉没有电话号码（或其他属性）的联系人。在我们阅读的文档中：

CNContact 谓词

匹配联系人的谓词。 您只能使用这些谓词 使用 CNContactStore 和 CNContactFetchRequest。

• predicateForContactsMatchingName：返回谓词以查找与指定名称匹配的联系人。
• predicateForContactsWithIdentifiers：返回谓词以查找与指定标识符匹配的联系人。
• predicateForContactsInGroupWithIdentifier：返回谓词以查找属于指定组的成员的联系人。
• predicateForContactsInContainerWithIdentifier：返回谓词以查找指定容器中的联系人。

另外：

不支持复合谓词。

因此，进行过滤的唯一方法是省略将没有电话号码的联系人添加到结果数组中。例如，这可以在enumerateContactsWithFetchRequest 的块中完成。
