Below code will work even if you have not configured email in your device.
Here is the code:
- (IBAction) sendEmail:(id)sender
{
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
{
MFMailComposeViewController *picker = [[MFMailComposeViewController alloc] init];
picker.mailComposeDelegate = self;
[picker setSubject:#"Hello from DShah!"];
NSArray *toRecipients = [NSArray arrayWithObject:#"first#example.com"];
NSArray *ccRecipients = [NSArray arrayWithObjects:#"second#example.com", #"third#example.com", nil];
NSArray *bccRecipients = [NSArray arrayWithObject:#"fourth#example.com"];
[picker setToRecipients:toRecipients];
[picker setCcRecipients:ccRecipients];
[picker setBccRecipients:bccRecipients];
NSString *path = [[NSBundle mainBundle] pathForResource:#"userdata" ofType:#"abc"];
NSFileManager *fileManager = [NSFileManager defaultManager];
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *fullPath = [documentsDirectory stringByAppendingPathComponent:[NSString stringWithFormat:#"%#.abc", #"userdata"]];
NSData *myData = [NSData dataWithContentsOfFile:fullPath];
[picker addAttachmentData:myData mimeType:#"csv" fileName:#"userdata.abc"];
NSString *emailBody = #"It is raining in sunny California!";
[picker setMessageBody:emailBody isHTML:NO];
[self presentModalViewController:picker animated:YES];
[picker release];
}
-(void)launchMailAppOnDevice
{
NSString *recipients = #"mailto:first#example.com&subject=Hello from DShah!";
NSString *body = #"&body=It is cold in Winter!";
NSString *email = [NSString stringWithFormat:#"%#%#", recipients, body];
email = [email stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:email]];
}
Then implement the Delegate method as below....
- (void)mailComposeController:(MFMailComposeViewController*)controller didFinishWithResult:(MFMailComposeResult)result error:(NSError*)error
{
switch (result)
{
case MFMailComposeResultCancelled:
message = #"Result: canceled";
break;
case MFMailComposeResultSaved:
message = #"Result: saved";
break;
case MFMailComposeResultSent:
message = #"Result: sent";
break;
case MFMailComposeResultFailed:
message = #"Result: failed";
break;
default:
message = #"Result: not sent";
break;
}
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Email Demo" message:message delegate:nil cancelButtonTitle:#"OK" otherButtonTitles:nil, nil];
[alert show];
[alert release];
[self dismissModalViewControllerAnimated:YES];
}
