Sending Email on iOS

Introduction

We can use the email application on iOS devices to send emails.

Example Steps

1. Create a simple View based application.

2. Select the project file, then select the target, and add the MessageUI.framework.

3. Add a button in ViewController.xib and create an action for sending an email.

4. Update ViewController.h as follows:

   #import <UIKit/UIKit.h>
   #import <MessageUI/MessageUI.h>
   
   @interface ViewController : UIViewController<MFMailComposeViewControllerDelegate>
   {
       MFMailComposeViewController *mailComposer;
   }
   
   -(IBAction)sendMail:(id)sender;
   
   @end
   

5. Update ViewController.m as follows:

   #import "ViewController.h"
   
   @interface ViewController ()
   
   @end
   
   @implementation ViewController
   
   - (void)viewDidLoad
   {
       [super viewDidLoad];   
   }
   
   - (void)didReceiveMemoryWarning
   {
       [super didReceiveMemoryWarning];
       // Dispose of any resources that can be recreated.
   }
   
   -(void)sendMail:(id)sender{
       mailComposer = [[MFMailComposeViewController alloc]init];
       mailComposer.mailComposeDelegate = self;
       [mailComposer setSubject:@"Test mail"];
       [mailComposer setMessageBody:@"Testing message for the test mail" isHTML:NO];
       [self presentModalViewController:mailComposer animated:YES];
   }
   
   #pragma mark - mail compose delegate
   -(void)mailComposeController:(MFMailComposeViewController *)controller 
    didFinishWithResult:(MFMailComposeResult)result error:(NSError *)error{
      if (result) {
           NSLog(@"Result : %d",result);
       }
       if (error) {
           NSLog(@"Error : %@",error);
       }
       [self dismissModalViewControllerAnimated:YES];
   
   }
   
   @end
   

Output

When running the application, you will see the following output:

When you click the "send email" button, you will see the following result:
