ios调用系统邮件

1.引入MessageUI.framework框架

2.实例化类MFMailComposeViewController，判断用户的设备是否设置邮箱 if ([mailClass canSendMail])

3.具体代码：

MFMailComposeViewController *mailPicker = [[MFMailComposeViewController alloc] init];     //创建邮件controller

mailPicker.mailComposeDelegate = self;  //设置邮件代理

[mailPicker setSubject:@"Send WebView ScreenShot"]; //邮件主题

[mailPicker setToRecipients:[NSArray arrayWithObjects:@"[email protected]",

@"[email protected]", nil]]; //设置发送给谁，参数是NSarray

//cc

//   [mailPicker setCcRecipients:[NSArray arrayWithObject:@"[email protected]"]]; //可以添加抄送

//bcc

// [mailPicker setBccRecipients:[NSArray arrayWithObject:@"[email protected]"]];

[mailPicker setMessageBody:@"WebShotScreen n in Attachment!" isHTML:NO];     //邮件主题

NSData *imageData = UIImagePNGRepresentation(viewImage);//这里获取截图存入NSData，用于发送附件

[mailPicker addAttachmentData:imageData mimeType:@"image/png" fileName:@"WebScreenShot"];//发送附件的NSData，类型，附件名

[self presentModalViewController:mailPicker animated:YES];   //把当前controller变为邮件controller

4.实现代理方法

- (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];

}
