- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex
{
if(buttonIndex==1)

Cocktails*c=[[Cocktails alloc]init];
_arrTextField=[NSArray arrayWithObjects:_txtName,_txtIngredients,_txtPreper,_txtServe,_txtFrom ,nil];
NSLog(#"send email");
if ([MFMailComposeViewController canSendMail])
{
NSMutableArray*recipients=[[NSMutableArray alloc]init];
[recipients addObject:#"maya1580#gmail.com"];
MFMailComposeViewController *controller= [[MFMailComposeViewController alloc]init];
controller.mailComposeDelegate= self;
[controller addAttachmentData:_imgDrink mimeType:#"image/png" fileName:#"Myimage"];
[controller setSubject:#"my cocktail"];
[controller setMessageBody: _arrTextField isHTML:NO];
[controller setToRecipients:recipients];
}
else
{
UIAlertView* alert=[[UIAlertView alloc]initWithTitle:#"Alert" message:#"Your devise is not set up for Email" delegate:self cancelButtonTitle:#"OK" otherButtonTitles:Nil, nil];
[alert show];
// [alert release];
}

Answer 1

You never present the mail controller. It needs to be presented like any other modal view controller.

Answer 2

Here that should help:
-(void)mailComposeController:(MFMailComposeViewController *)controller didFinishWithResult:(MFMailComposeResult)result error:(NSError *)error
{
switch (result)
{
case MFMailComposeResultCancelled:
NSLog(#"Mail cancelled: you cancelled the operation and no email message was queued.");
break;
case MFMailComposeResultSaved:
NSLog(#"Mail saved: you saved the email message in the drafts folder.");
break;
case MFMailComposeResultSent:
NSLog(#"Mail send: the email message is queued in the outbox. It is ready to send.");
break;
case MFMailComposeResultFailed:
NSLog(#"Mail failed: the email message was not saved or queued, possibly due to an error.");
break;
default:
NSLog(#"Mail not sent.");
break;
}
// Remove the mail view
[self dismissModalViewControllerAnimated:YES];
}
-(IBAction)sendCode:(id)sender {
if ([MFMailComposeViewController canSendMail])
{
MFMailComposeViewController *mailer = [[MFMailComposeViewController alloc] init];
mailer.mailComposeDelegate = self;
[mailer setSubject:#"Your subject"];
NSArray *toRecipients = [NSArray arrayWithObjects:#"maya1580#gmail.com", nil];
[mailer setToRecipients:toRecipients];
UIImage *myImage = [UIImage imageNamed:#"MyImage.png"];
NSData *imageData = UIImagePNGRepresentation(myImage);
[mailer addAttachmentData:imageData mimeType:#"image/png" fileName:#"myimag
e"];
NSString *emailBody =
#"your body";
[mailer setMessageBody:emailBody isHTML:NO];
[mailer setModalTransitionStyle:UIModalTransitionStyleCrossDissolve];
[self presentModalViewController:mailer animated:YES];
}
else {
{
UIAlertView *alert2 = [[UIAlertView alloc] initWithTitle:#"Error"
message:#"Your device doesnt support that action."
delegate:nil
cancelButtonTitle:#"Okay"
otherButtonTitles:nil];
[alert2 show];
}
}
}
and in the .h file add:
#import <UIKit/UIKit.h>
#import <MessageUI/MessageUI.h>
#interface Controller : UIViewController <MFMailComposeViewControllerDelegate> {
}
-(IBAction)send:(id)sender;
#end

You cant send automaticaly email because apple wont let you do this kind of things without user knowledge. You must present presentModalView!
