iphone应用发送电子邮件 [英] iphone app send email

问题描述

我知道如何通过启动邮件应用程序然后返回到我的应用程序在我的应用程序中发送电子邮件，但我希望我的应用程序能够发送电子邮件，而不打开邮件应用程序。
例如，我的应用程序中有一个按钮，该按钮将发送一封电子邮件。我会通知用户电子邮件已发送...

I know how to send an email within my app by launching the Mail app then returning to my app... but I would like to my app to be able to send email without opening the mail app. For exemple i'd have a button in my app clicking that button would send out an email. I will then notify the user that the email has been sent...

有没有人这样做？

这是一个示例代码使用MFMailComposeViewController发送电子邮件。

Here is a sample code to send email using MFMailComposeViewController.

-(IBAction)showPicker:(id)sender {
// This sample can run on devices running iPhone OS 2.0 or later  
// The MFMailComposeViewController class is only available in iPhone OS 3.0 or later. 
// So, we must verify the existence of the above class and provide a workaround for devices running 
// earlier versions of the iPhone OS. 
// We display an email composition interface if MFMailComposeViewController exists and the device can send emails.
// We launch the Mail application on the device, otherwise.

Class mailClass = (NSClassFromString(@"MFMailComposeViewController"));
if (mailClass != nil)
{
    // We must always check whether the current device is configured for sending emails
    if ([mailClass canSendMail])
    {
        [self displayComposerSheet];
    }
    else
    {
        [self launchMailAppOnDevice];
    }
}
else
{
    [self launchMailAppOnDevice];
}
}

-(void)displayComposerSheet {
// Displays an email composition interface inside the application. Populates all the Mail fields. 

MFMailComposeViewController *picker = [[MFMailComposeViewController alloc] init];
picker.mailComposeDelegate = self;

[picker setSubject:@"Hello from California!"];


// Set up recipients
NSArray *toRecipients = [NSArray arrayWithObject:@"[e-mail]"]; 
NSArray *ccRecipients = [NSArray arrayWithObjects:@"[e-mail]", @"[e-mail]", nil]; 
NSArray *bccRecipients = [NSArray arrayWithObject:@"[e-mail]"]; 

[picker setToRecipients:toRecipients];
[picker setCcRecipients:ccRecipients];  
[picker setBccRecipients:bccRecipients];

// Attach an image to the email
NSString *path = [[NSBundle mainBundle] pathForResource:@"rainy" ofType:@"png"];
NSData *myData = [NSData dataWithContentsOfFile:path];
[picker addAttachmentData:myData mimeType:@"image/png" fileName:@"rainy"];

// Fill out the email body text
NSString *emailBody = @"It is raining in sunny California!";
[picker setMessageBody:emailBody isHTML:NO];

[self presentModalViewController:picker animated:YES];
[picker release];
}


- (void)mailComposeController:(MFMailComposeViewController*)controller didFinishWithResult:(MFMailComposeResult)result error:(NSError*)error {  
// Dismisses the email composition interface when users tap Cancel or Send. Proceeds to update the message field with the result of           the operation.
message.hidden = NO;
// Notifies users about errors associated with the interface
switch (result)
{
    case MFMailComposeResultCancelled:
        message.text = @"Result: canceled";
        break;
    case MFMailComposeResultSaved:
        message.text = @"Result: saved";
        break;
    case MFMailComposeResultSent:
        message.text = @"Result: sent";
        break;
    case MFMailComposeResultFailed:
        message.text = @"Result: failed";
        break;
    default:
        message.text = @"Result: not sent";
        break;
}
[self dismissModalViewControllerAnimated:YES];
 }

-(void)launchMailAppOnDevice {

// Launches the Mail application on the device.
NSString *recipients = @"mailto:[e-mail]?cc=[e-mail],[e-mail]&subject=Hello from California!";
NSString *body = @"&body=It is raining in sunny California!";

NSString *email = [NSString stringWithFormat:@"%@%@", recipients, body];
email = [email stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];

[[UIApplication sharedApplication] openURL:[NSURL URLWithString:email]];
}
