Swift

使用MessageUI.framework框架除了可以发送短信，还能发送Email，步骤如下：

（1）首先判断设备是否有发送邮件功能

（2）如果设备允许发送邮件，创建一个MFMailComposeViewController视图控制器，并对其设置邮件标题，正文内容，收件人，附件等。

（3）邮件发送后，会执行回调代理方法，可以获取发送结果（成功，失败或取消）

 

效果图如下：

代码如下：

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62
