In this tutorial i will be showing you how to directly email from your app Features:

1 Round Rect Button

In app emailing is a great feature for any developer and can be used to gather instant feedback from the customer or even a way to share your apps content improving the app and reaching a higher audience

The Code

Play the video to get a step by step walkthrough and all code can be copy and pasted

1.新建立一个项目,view based application(with storyboard.ARC)

2.需要引入UIMessage Library (Build Phases => Link Binary With Libraries => +(添加) => MessageUI.framework(可以搜索查找))

3.编辑ViewController.h文件

#import <UIKit/UIKit.h>
#import <MessageUI/MessageUI.h>
@interface ViewController : UIViewController <MFMailComposeViewControllerDelegate>

-(IBAction)sendMail:(id)sender;
@end

4.在MainStoryboard.storyboard文件中添加一个Round Rect Button ，关联到sendMail 函数。

5.在ViewController.m文件中添加如下方法

-(IBAction)sendMail:(id)sender
{
    if ([MFMailComposeViewController canSendMail]) 
    {
        MFMailComposeViewController *mail = [[MFMailComposeViewController alloc] init];
        mail.mailComposeDelegate = self;
        [mail setSubject:@"Hi here is Subject!"];
        NSArray *toRecipients = [NSArray arrayWithObjects:@"justcoding@gmail.com", nil];
        [mail setToRecipients:toRecipients];
        [mail setCcRecipients:toRecipients];
        
        NSString *emailBody = @"This is a test email !";
        
        [mail setMessageBody:emailBody isHTML:NO];
        mail.modalPresentationStyle = UIModalPresentationFormSheet;
        [self presentModalViewController:mail animated:YES];
    } 
    else 
    {
        UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"ERROR" message:@"Email is not supported on your device" delegate:self cancelButtonTitle:@"Cancel" otherButtonTitles: nil];
        [alert show];
    }
}
-(void)mailComposeController:(MFMailComposeViewController *)controller didFinishWithResult:(MFMailComposeResult)result error:(NSError *)error
{
    switch (result) 
    {
        case MFMailComposeResultCancelled:
            NSLog(@"Cancelled");
            break;
        case MFMailComposeResultSaved:
            NSLog(@"Message saved in drafts folder");
            break;
            
        case MFMailComposeResultSent:
            NSLog(@"Message is sent");
            break;
            
        case MFMailComposeResultFailed:
            NSLog(@"Message not sent due to error");
            break;
        default:
            NSLog(@"Mail not sent");
            break;
    }
    [self dismissModalViewControllerAnimated:YES];
}
