MFMailComposeViewController发送邮件的实例

本文转载至 http://blog.csdn.net/liufeng520/article/details/7585140

 

1. iPhone API已经提供了系统写邮件界面的接口,使用MFMailComposeViewController，用来显示界面.
2. 项目中需要添加MessageUi.framework。头文件加入MFMailComposeViewControllerDelegate。#import <MessageUI/MessageUI.h>
3. sendMailViewController.m文件的实现：
4. - (void)viewDidLoad
5. {
6. UIButton *button = [UIButton buttonWithType: UIButtonTypeRoundedRect];
7. button.frame = CGRectMake(0, 40, 320, 50);
