ios - 通过 Xcode 从 iPhone/iPad 设置区域获取邮件地址

Question

我正在尝试使用目标 c 从 iPhone/iPad 设置区域获取电子邮件 ID 和其他详细信息到我的代码。任何建议将不胜感激。提前致谢。

Answer 1

您无法在设置中获取默认电子邮件，它将仅由 mfmailcomposeviewcontroller 处理

Answer 2

据我了解您的问题，您希望从用户那里获取个人数据。为此，您需要调用 AdressBook API：

地址簿 API 文档

Answer 3

这是工作示例。它将所有电子邮件和全名加载到传递的数组中。以您需要的方式定制此代码，例如，您可以找到一些特定的联系人并从中获取所有信息。

- (NSMutableArray *)loadContactsFromAB:(NSMutableArray *)contacts
{
        ABAddressBookRef addressBook = ABAddressBookCreate();
        CFArrayRef allPeople = ABAddressBookCopyArrayOfAllPeople(addressBook);
        CFIndex nPeople = ABAddressBookGetPersonCount(addressBook);

        for (int i = 0 ; i < nPeople ; i++ ) {
                ABRecordRef person = CFArrayGetValueAtIndex(allPeople, i);
                NSString *firstName = ABRecordCopyValue(person, kABPersonFirstNameProperty);
                NSString *lastName = ABRecordCopyValue(person, kABPersonLastNameProperty);

                NSString *fullName;

                if (firstName && lastName) {
                        fullName = [NSString stringWithFormat:@"%@ %@", firstName, lastName];
                } else {
                        if (firstName) {
                                fullName = [NSString stringWithString:firstName];
                        } else if (lastName) {
                                fullName = [NSString stringWithString:lastName];
                        } else {
                                continue;
                        }
                }

                NSString *email = nil;
                ABMultiValueRef emails = ABRecordCopyValue(person, kABPersonEmailProperty);

                if (emails) {
                        NSArray *emailAddresses = [(NSArray *)ABMultiValueCopyArrayOfAllValues(emails) autorelease];
                        if (emailAddresses && [emailAddresses count] > 0)
                                email = [emailAddresses objectAtIndex:0];
                        CFRelease(emails);
                }
                if (email) {
                        NSDictionary *contact = [NSDictionary
                                                 dictionaryWithObjectsAndKeys:fullName, @"name",
                                                 email, @"email", nil];
                        [self addContact:contacts contact:contact];
                }
                if (firstName)
                        CFRelease(firstName);
                if (lastName)
                        CFRelease(lastName);
        }

        CFRelease(allPeople);
        CFRelease(addressBook);
        return contacts;
}
