邮件发送功能是由MessageUI Framework提供的,这个框架是iPhone sdk中最简单的框。由一个类、一个视图控制器,一个protocol组成。
一、创建视图控制器:
?
MFMailComposeViewController *mc = [[MFMailComposeViewController alloc] init]; mc.mailComposeDelegate = self ; |
二、设置邮件主题:
[mc setSubject:@"Hello, World!"];
三、设置收件人,收件人有三种:
1、设置主收件人
?
[mc setToRecipients:[ NSArray arrayWithObjects:@ "zhuqi0@126.com" , "@dave@iphonedevbook.com" , nil ]; |
2、设置cc
[mc setCcRecipients:[NSArray arrayWithObject:@"zhuqil@163.com"]];
3、设置bcc
[mc setBccRecipients:[NSArray arrayWithObject:@"secret@gmail.com"]];
四、设置邮件主体,有两种格式。
一种是纯文本
[mc setMessageBody:@"Watson!!!\n\nCome here, I need you!" isHTML:NO];
一个是html格式
?
[mc setMessageBody:@ "<HTML><B>Hello, Joe!</B><BR/>What do you know?</HTML>" isHTML: YES ]; |
五、添加附件
添加附件需要三个参数,一个是NSData类型的附件,一个是mime type,一个附件的名称。
NSString *path = [[NSBundle mainBundle] pathForResource:@"blood_orange" ofType:@"png"]; NSData *data = [NSData dataWithContentsOfFile:path]; [mc addAttachmentData:data mimeType:@"image/png" fileName:@"blood_orange"];
六、视图呈现
[self presentModalViewController:mc animated:YES]; [mc release];
七、视图控制器的委托方法
邮件视图控制器的委托方法包含在MFMailComposeViewControllerDelegate中,无论用户是否发送或取消发送,不论系统是否能够发送邮件,
方法 mailComposeController:didFinishWithResult:error: gets called都会被调用。
- (void)mailComposeController:(MFMailComposeViewController*)controller didFinishWithResult:(MFMailComposeResult)result error:(NSError*)error { switch (result) { case MFMailComposeResultCancelled: NSLog(@"Mail send canceled..."); break; case MFMailComposeResultSaved: NSLog(@"Mail saved..."); break; case MFMailComposeResultSent: NSLog(@"Mail sent..."); break; case MFMailComposeResultFailed: NSLog(@"Mail send errored: %@...", [error localizedDescription]); break; default: break; } [self dismissModalViewControllerAnimated:YES]; }
