问题描述

我正在尝试设置它，以便人们可以从我的应用程序中发送电子邮件。我引用这个帖子来做这个，但是我在构建中收到这些警告：

然后当我运行它，它的错误：

and then when I run it, it bugs:

我想知道如果我把代码放在错误的地方。只要你知道我已经把

I'm wondering if I've simply placed the code in the wrong area. Just so you know I have placed

#import <MessageUI/MessageUI.h>

在头文件中。

谢谢帮助！

似乎问题在于如何设置ViewController。实际上，我的所有UI代码都在一个单独的对象中，如下所示。这使我很难理解哪个代码在哪里。任何建议？

It seems as if the problem lies within how my ViewController is setup. In fact all my UI code is in a separate object as shown below. This is making it difficult for me to understand which code goes where. Any advice?

推荐答案

看起来你的SpeakHereController不是一个UIViewController。

Well it looks like your SpeakHereController isn't a UIViewController.

因此，它找不到用于呈现和关闭modalViewController的方法。
您还需要实现 MFMailComposeViewControllerDelegate ，将其添加到您的viewcontroller。

Therefore it can't find the methods for presenting and dismissing the modalViewController. Also you need to implement the MFMailComposeViewControllerDelegate, add it to your viewcontroller.
