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.
项目中需要添加MessageUi.framework。头文件加入MFMailComposeViewControllerDelegate。#import <MessageUI/MessageUI.h>
sendMailViewController.m文件的实现：
- (void)viewDidLoad
{
UIButton *button = [UIButton buttonWithType: UIButtonTypeRoundedRect];
button.frame = CGRectMake(0, 40, 320, 50);
