How to Populate an email recipient depending on which button is pressed? - ios

Question

I have an app that is for 3 different offices and I would like to be able to choose which office the resulting collated data will be sent to via an email. I would like to use a different button for each of the offices that will automatically populate an email recipient and then a final button at the end will collate all the information and attach it all to an email. Is there any way of doing this? I have the send button figured out, its the populating the recipient that I can't work out.
Here is the email part that I have but is populated by 1 email address rather than depending on a button press at the moment.

Answer 1

Why not implement the method that's called when your button is pressed, parse out the id of the button from the info that was passed in, and then set the "to" field of the email accordingly?

Answer 2

-(IBAction)buttonPressed:(id)sender{
UIButton *button = (UIButton *)sender;
NSLog(#"%d", [button tag]);
switch(button.tag) {
case 1 :
// set label.text = example1#example.com
break;
case 2 :
// set label.text = example2#example.com
break;
}
}

Answer 3

Try this
- (IBAction)sendEmail:(id)sender {
NSMutableString *report = [NSMutableString stringWithFormat: #"<br><br> <b>Name:</b> %# <br> <b>Email Address:</b> %# <br><br> <b>Date & Time of Near Miss:</b> %# <br><br> <b>Location of Near Miss:</b> %# <br> <b>GPS Location:</b> %# <br><br> <b>Observers Team:</b> %# <br> <b>Affected Team:</b> %# <br><br> <b>Rating Classification:</b> %# <br><br> %# <br><br> <b>Category:</b> %# <br><b>Observation Description:</b> %# <br><br> <b>Type of Work Activity:</b> %# <br><br><b>Image:</b><br>", name, emailaddress, date, location, gps, observers, affected, rating, thirdparty, category, message, activity];
NSLog(#"Near Miss Report: %#", report);
NSMutableString *testoMail = [NSMutableString stringWithFormat:report];
NSLog(#"%#", testoMail);
MFMailComposeViewController *picker = [[MFMailComposeViewController alloc] init];
picker.mailComposeDelegate = self;
[picker setSubject: rating];
// Set up the recipients.
NSArray *toRecipients;
NSArray *ccRecipients;
NSArray *bccRecipients;
switch([sender tag]) {
case 0 : {
// set label.text = example1#example.com
toRecipients = [NSArray arrayWithObjects:#"example#example.com",nil];
ccRecipients = [NSArray arrayWithObjects:#"second#example.com",#"third#example.com", nil];
bccRecipients = [NSArray arrayWithObjects:#"four#example.com",nil];
break;
}
case 1 : {
// set label.text = example2#example.com
toRecipients = [NSArray arrayWithObjects:#"example#example.com",nil];
ccRecipients = [NSArray arrayWithObjects:#"second#example.com",#"third#example.com", nil];
bccRecipients = [NSArray arrayWithObjects:#"four#example.com",nil];
break;
}
case 2 : {
// set label.text = example2#example.com
toRecipients = [NSArray arrayWithObjects:#"example#example.com",nil];
ccRecipients = [NSArray arrayWithObjects:#"second#example.com",#"third#example.com", nil];
bccRecipients = [NSArray arrayWithObjects:#"four#example.com",nil];
break;
}
}
if(toRecipients.length >0) {
[picker setToRecipients:toRecipients];
}
if(ccRecipients.length >0) {
[picker setCcRecipients:ccRecipients];
}
if(bccRecipients.length >0) {
[picker setBccRecipients:bccRecipients];
}
// Attach an image to the email.
NSData *imageData = UIImagePNGRepresentation([imageView image]);
[picker addAttachmentData:imageData mimeType:#"image/png" fileName:#"NearMiss"];
// Fill out the email body text.
//NSMutableString *emailBody;

// Present the mail composition interface.
[self presentViewController:picker animated:YES completion:nil];
