如何通过iOS模拟器发送电子邮件？ [英] How to send an email through iOS simulator?

问题描述

我想知道是否可以通过iPhone模拟器发送电子邮件。我看到
教程通过iphone发送电子邮件如下：

I want to know if it's possible to send email through iPhone simulator. I have seen the tutorial for sending an email through iphone as below:

http://www.edumobile.org/iphone/iphone-programming-tutorials/compose-mail-application-in-iphone /

现在要测试，是否有必要拥有真实的设备？如果我想通过iPhone模拟器发送电子邮件
是什么方式？

Now to test it is it necessary to have real device? What is the way if I want to send email through iPhone simulator?

推荐答案

你必须依靠iOS在 mailComposeController：didFinishWithResult：error：中传回的 MFMailComposeResult 是正确的。模拟器假冒结果;没有实际的邮件发送，虽然它说 MFMailComposeResultSent 。

You have to rely on the iOS that the MFMailComposeResult that is handed back in mailComposeController:didFinishWithResult:error: is correct. The simulator fakes that result; no actual mail is sent although it says MFMailComposeResultSent.

提及的教程错过了一个重要的一点strong>：在使用 MFMailComposeViewController 之前，首先要检查 [MFMailComposeViewController canSendMail] 。如果用户尚未在其设备上配置邮件，则将返回 NO 。如果您必须在3.0之前支持iOS版本，则正确的方法是检查课程 MFMailComposeViewController 是否存在：

The tutorial mentioned misses an important point: The first thing you should do before using MFMailComposeViewController is to check [MFMailComposeViewController canSendMail]. That will return NO, if the user hasn't configured mail on their device. If you must support an iOS version prior to 3.0 the correct way is to check if the class MFMailComposeViewController exists:

Class mailClass = (NSClassFromString(@"MFMailComposeViewController"));
if (mailClass != nil)
{
    if ([mailClass canSendMail])
    {
        [self displayComposerSheet];
    }
    else
    {
        [self launchMailAppOnDevice];
    }
}
else
{
    [self launchMailAppOnDevice];
}

canSendMail问题只能在真实的设备上进行测试。如果您不检查canSendMail并且用户没有配置邮件帐户，它将崩溃。

The canSendMail-issue can only be tested on a real device though. It will crash if you don't check canSendMail and the user has no mail account configured.
