iOS开发之邮件发送

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:@"[email protected]",     
        "@[email protected]", nil]; 
2、设置cc

[mc setCcRecipients:[NSArray arrayWithObject:@"[email protected]"]]; 
3、设置bcc

[mc setBccRecipients:[NSArray arrayWithObject:@"[email protected]"]];  
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,不论系统是否能够实现邮件发送,

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];  
 }
