iOS:如何获取所有者的电子邮件地址？

Question

在 iOS 中，如何读取存储在 iPhone 中的所有者电子邮件地址？在我的应用程序中，我想让用户选择他希望将哪个电子邮件地址与自定义服务相关联。在Android上，我会让他选择他的GMail地址，但在iOS上，似乎没有获取apple id电子邮件的选项，对吗？那么有没有可能检索所有存储的电子邮件地址并让用户选择其中一个？我真的需要一个电子邮件地址。唯一 ID、设备 ID 或类似内容不适用于我想要实现的目标。

谢谢

为什么不显示地址簿让用户选择和电子邮件地址？

将 AddressBook 和 AddressBookUI 框架添加到您的项目中。 将它们导入您的 .h 并添加协议(protocol) ABPeoplePickerNavigationControllerDelegate。

然后调用地址簿:

- (void) chooseContact:(id)sender {
    ABPeoplePickerNavigationController *picker = [[ABPeoplePickerNavigationController alloc] init];
    picker.peoplePickerDelegate = self;
    [self presentModalViewController:picker animated:YES];
    [picker release];
}

您实现几个必需的委托(delegate)方法来获取电子邮件地址并关闭地址簿:

// call when the user cancel
 - (void) peoplePickerNavigationControllerDidCancel:(ABPeoplePickerNavigationController *)peoplePicker {
    [self dismissModalViewControllerAnimated:YES];
}

让用户输入联系方式:

- (BOOL)peoplePickerNavigationController:(ABPeoplePickerNavigationController *)peoplePicker shouldContinueAfterSelectingPerson:(ABRecordRef)person {
    return YES;
}

然后使用所选的电子邮件地址执行您的操作:

- (BOOL)peoplePickerNavigationController:(ABPeoplePickerNavigationController *)peoplePicker shouldContinueAfterSelectingPerson:(ABRecordRef)person property:(ABPropertyID)property identifier:(ABMultiValueIdentifier)identifier {
    if (property == kABPersonEmailProperty) {
         //assumed you have a property email in your class
         self.email = (NSString *)ABRecordCopyValue(person, kABPersonEmailProperty);
         [self dismissModalViewControllerAnimated:YES];
    }
    return NO;
}
