How to fill email with To and Subject in iPhone? - objective-c

Question

I have a button in my app called contact Us! Is there a way to open up the Eamil client in iPhone filled with To and Subject that I provide?

Answer 1

You will want to use the MFMailComposeViewController class. Here's the relevant part from Apple's MailComposer example:
MFMailComposeViewController *picker = [[MFMailComposeViewController alloc] init];
picker.mailComposeDelegate = self;
[picker setSubject:#"Hello from California!"];
// Set up recipients
NSArray *toRecipients = [NSArray arrayWithObject:#"first#example.com"];
[picker setToRecipients:toRecipients];
[self presentModalViewController:picker animated:YES];
[picker release];
The MailComposer sample also shows you how to open the external mail app:
NSString *recipients = #"mailto:first#example.com&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]];

Answer 2

Check out MFMailComposeViewController. You can set the Subject, To Field, and even populate the body with HTML.

Answer 3

Sure you can.
- (void)emailExport:(NSString *)filePath
{
MFMailComposeViewController *picker = [[MFMailComposeViewController alloc] init];
picker.mailComposeDelegate = self;
// Set the subject of email
[picker setSubject:#"My desired subject"];
// Add email addresses
// Notice three sections: "to" "cc" and "bcc"
NSString *valueForEmail = #"myEmail#gmail.com";
NSString *valueForCCEmail = #"myCcEmail";
if( valueForEmail == nil || [valueForEmail isEqualToString:#""])
{
UIAlertView *alert=[[UIAlertView alloc] initWithTitle:#"Please set an email address before sending a time entry!" message:nil delegate:self cancelButtonTitle:#"OK" otherButtonTitles:nil];
[alert show];
[alert release];
return;
}
else {
[picker setToRecipients:[NSArray arrayWithObjects:valueForEmail, nil]];
}
if(valueForCCEmail != nil || ![valueForCCEmail isEqualToString:#""])
{
[picker setCcRecipients:[NSArray arrayWithObjects:valueForCCEmail, nil]];
}
// Fill out the email body text
NSString *emailBody = #"My email body text.";
// This is not an HTML formatted email
[picker setMessageBody:emailBody isHTML:NO];
// Show email view
[self presentModalViewController:picker animated:YES];
// Release picker
[picker release];
}
