How to send an E-Mail inside of an app in Xcode? - ios

Question

I am new to xcode, and am wondering how to send email in an app! My code is below, but I keep getting the error "No visible #interface for 'jakem' declares the selector 'presentViewControllerAnimated:'". Is my code completely wrong? Or did I just forget to declare the selector, and how do I declare the selector? I have researched all over the internet for at least an hour, and nothing is working. Someone please help me!
-(IBAction)sendEmail{
MFMailComposeViewController *composer = [[MFMailComposeViewController alloc] init];
[composer setMailComposeDelegate:self];
if ([MFMailComposeViewController canSendMail]) {
[composer setToRecipients:[NSArray arrayWithObjects:#"FrankMurphy.CEO#RomansXIII.com", nil]];
[composer setModalTransitionStyle:UIModalTransitionStyleCrossDissolve];
[self presentViewController:composer animated:YES];
}
}
-(void)mailComposeController:(MFMailComposeViewController *)controller didFinishWithResult:(MFMailComposeResult)result error:(NSError *)error {
if(error) {
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"error" message:[NSString stringWithFormat:#"error %#", [error description]] delegate:nil cancelButtonTitle:#"dismiss" otherButtonTitles:nil, nil];
[alert show];
[self dismissViewControllerAnimated:YES];
}
else {
[self dismissViewControllerAnimated:YES];
}
}

in .h header file....
#import <UIKit/UIKit.h>
#import <MessageUI/MessageUI.h>
#interface SimpleEmailViewController : UIViewController <MFMailComposeViewControllerDelegate> // Add the delegate
- (IBAction)showEmail:(id)sender;
#end
in .m implementation file.....
- (IBAction)showEmail:(id)sender {
// Email Subject
NSString *emailTitle = #"Test Email";
// Email Content
NSString *messageBody = #"iOS programming is so fun!";
// To address
NSArray *toRecipents = [NSArray arrayWithObject:#"info#finetechnosoft.in"];
MFMailComposeViewController *mc = [[MFMailComposeViewController alloc] init];
mc.mailComposeDelegate = self;
[mc setSubject:emailTitle];
[mc setMessageBody:messageBody isHTML:NO];
[mc setToRecipients:toRecipents];
// Present mail view controller on screen
[self presentViewController:mc animated:YES completion:NULL];
}
- (void) mailComposeController:(MFMailComposeViewController *)controller didFinishWithResult:(MFMailComposeResult)result error:(NSError *)error
{
switch (result)
{
case MFMailComposeResultCancelled:
NSLog(#"Mail cancelled");
break;
case MFMailComposeResultSaved:
NSLog(#"Mail saved");
break;
case MFMailComposeResultSent:
NSLog(#"Mail sent");
break;
case MFMailComposeResultFailed:
NSLog(#"Mail sent failure: %#", [error localizedDescription]);
break;
default:
break;
}
// Close the Mail Interface
[self dismissViewControllerAnimated:YES completion:NULL];
}

Check if you are MFMailComposeViewControllerDelegate.
You do this like
#interface YouClassName : UIViewController <MFMailComposeViewControllerDelegate>
#end

Answer 3

I think you're using the wrong method. Try
[self presentViewController:(UIViewController *) animated:(BOOL) completion:(void)completion];
instead of:
[self presentViewController:composer animated:YES];

I work for Sendgrid. We have an Objective-c library that lets you quickly send email from inside your app, https://github.com/sendgrid/sendgrid-objc. You can use cocoapods to quickly install the library in your project.
Then sending the email from your (IBAction) would look like this:
-(IBAction)sendEmail{
sendgrid *msg = [sendgrid user:#"username" andPass:#"password"];
msg.to = #"FrankMurphy.CEO#RomansXIII.com";
msg.from = #"me#bar.com";
msg.text = #"hello world";
msg.html = #"<h1>hello world!</h1>";
[msg sendWithWeb];
}
