Question

我想（仅在使用Objective-C的iOS中）获取具有电话号码的联系人，但我该怎么做？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？谢谢你的帮助！

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 Predicates

谓词匹配联系人。 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：返回谓词以查找指定组中成员的联系人。

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向结果数组添加没有电话号码的联系人。例如，可以在enumerateContactsWithFetchRequest。

的块中完成

列出带有电话号码的联系人
