iOS：如何获取所有者电子邮件地址？

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,我想让用户选择他要与自定义服务关联的电子邮件地址.在 Android上,我可以让他选择他的GMail地址,但在iOS上,似乎没有选择获取apple id的电子邮件,对吧？那么有可能检索所有存储的电子邮件地址,并让用户选择其中的一个？我真的需要一个电子邮件地址.唯一的ID,设备ID或类似功能将无法与我想要实现的功能一起使用.

谢谢

解决方法

为什么不出示通讯录,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.
将它们导入到.h中并添加协议ABPeoplePickerNavigationControllerDelegate.

然后打电话给地址簿：

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

您实施几个必需的委托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做你所想要的：

- (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;
}
