iPhone/iPad利用系统MFMailComposeViewController调用系统邮件,比如:在程序中点击按钮后,调出发送邮件的界面(MFMailComposeViewController实现).
MFMailComposeViewController: 类提供了一个标准接口,它管理的编辑和发送电子邮件。您可以使用此视图控制器显示在您的应用程序标准的电子邮件意见,并填充与初始值,如主题,电子邮件收件人,正文和附件,查看字段。用户可以编辑您所指定的初始内容,并选择发送电子邮件或取消操作。
1、添加类库{Frameworks}:MessageUI.framework;
2、实现代码:
/*
* @DO 发送邮件
* @param sender
*/
- (void) sendEmail:(id)sender
{
         MFMailComposeViewController *mailCompose = [[MFMailComposeViewController alloc] init];
         if(mailCompose)
         {
              //设置代理
              [mailCompose setMailComposeDelegate:self];
              NSArray *toAddress = [NSArray arrayWithObject:@"****@***.com"];
              NSArray *ccAddress = [NSArray arrayWithObject:@"XXXX@XXX.com"];
              NSString *emailBody = @"<H1>邮件内容!</H1>";
              //设置收件人
              [mailCompose setToRecipients:toAddress];
              //设置抄送人
              [mailCompose setCcRecipients:ccAddress];
              //设置邮件内容          
              [mailCompose setMessageBody:emailBody isHTML:YES];
              //设置邮件主题
              [mailCompose setSubject:@"这里是主题"];
              //设置邮件附件{mimeType:文件格式|fileName:文件名}
              [mailCompose addAttachmentData:imageData mimeType:@"image/jpg" fileName:@"1.png"];
              //设置邮件视图在当前视图上显示方式
              [self presentModalViewController:mailCompose animated:YES];
         }
         [mailCompose release];
}
 
/*
* @DO 代理对邮件发送失败的处理
* @param controller
* @param result
* @param error
*/
-  (void)mailComposeController:(MFMailComposeViewController*)controller
                didFinishWithResult:(MFMailComposeResult)result
                                          error:(NSError*)error
{      
 
         switch (result)
         {
              case MFMailComposeResultCancelled:
              {
                     UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Send e-mail Cancel"
                                                                                                         message:@""
                                                                                                     delegate:self
                                                                                      cancelButtonTitle:@"OK"
                                                                                      otherButtonTitles:nil];
                     [alert show];
                     [alert release];
              }
                     break;
              case *********:
              {
                     UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"E-mail have been saved"
                                                                                                         message:@""
                                                                                                     delegate:self
                                                                                      cancelButtonTitle:@"OK"
                                                                                      otherButtonTitles:nil];
                     [alert show];
                     [alert release];
              }
                     break;
              default:
              {
                     UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"E-mail Not Sent"
                                                                                                         message:@""
                                                                                                     delegate:self
                                                                                      cancelButtonTitle:@"OK"
                                                                                      otherButtonTitles:nil];
                     [alert show];
                     [alert release];
              }
                     break;
         }
    //邮件视图消失
         [self dismissModalViewControllerAnimated:YES];
}


方式一、可以在项目的list属性文件中设置Localization native development region的属性值;
方式二、可以在调用MFMailComposeViewController的xib中设置Localization(方法如下:找到对应xib文件,右击该文件选择Get Infoà [General选项卡下单击{add Localization}])如台湾繁体{zh_TW}
总结:如果是调用MFMailComposeViewController为非xib形式,那就只能用方式一来支持国际化.
