iOS:如何获取所有者的电子邮件地址？

Question

在iOS中,如何阅读存储在iPhone中的所有者电子邮件地址？在我的应用中,我想让用户选择他想要与自定义服务关联的电子邮件地址.在Android上,我会让他选择他的GMail地址,但在iOS上,似乎没有选择获取apple id电子邮件,对吧？那么是否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.唯一的ID,设备ID或类似内容将无法满足我的目标.

谢谢

为什么不出示通讯录并让用户选择和发送电子邮件地址？

将AddressBook和AddressBookUI框架添加到项目中.在.h中导入它们并添加协议ABPeoplePickerNavigationControllerDelegate.

然后拨打地址簿:

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

您实现了几个必需的委托方法来获取电子邮件地址并关闭通讯簿:

// 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;
}
