ios 在 iPhone 应用程序中撰写邮件

Compose mail in the iPhone app

提问by K.Honda

In my app, I have an abouts page. I would like to place a round rect button which when I press it, I would be able to send an email to the company with an embedded email address.

在我的应用程序中，我有一个关于页面。我想放置一个圆形矩形按钮，当我按下它时，我可以向公司发送一封带有嵌入式电子邮件地址的电子邮件。

Are there any tutorials to do this?

是否有任何教程可以做到这一点？

Thanks in advance.

提前致谢。

You have to link against the MessageUIframework and use the class MFMailComposeViewController. Don't forget to import the framework (#import <MessageUI/MessageUI.h>).

您必须链接到MessageUI框架并使用类MFMailComposeViewController。不要忘记导入框架 ( #import <MessageUI/MessageUI.h>)。

The documentation with sample code: http://developer.apple.com/library/ios/#documentation/MessageUI/Reference/MFMailComposeViewController_class/Reference/Reference.html

带有示例代码的文档：http: //developer.apple.com/library/ios/#documentation/MessageUI/Reference/MFMailComposeViewController_class/Reference/Reference.html

Here's the code:

这是代码：

Obj-C:

对象-C：

(Don't forget to add the messageUI framework to your project!!!)

（不要忘记将 messageUI 框架添加到您的项目中！！！）

First import the message library:

首先导入消息库：

#import <MessageUI/MessageUI.h>

Then mark your self as a delegate like this:

然后像这样将自己标记为委托：

@interface MYViewController () <MFMailComposeViewControllerDelegate>

Then to pull up the composer (if user has email set up on their device):

然后拉起作曲家（如果用户在他们的设备上设置了电子邮件）：

- (IBAction)emailButtonPressed:(id)sender
{
    if ([MFMailComposeViewController canSendMail]) {
        MFMailComposeViewController *composeViewController = [[MFMailComposeViewController alloc] initWithNibName:nil bundle:nil];
        [composeViewController setMailComposeDelegate:self];
        [composeViewController setToRecipients:@[@"[email protected]"]];
        [composeViewController setSubject:@"example subject"];
        [self presentViewController:composeViewController animated:YES completion:nil];
    }
}

Then to handle the delegate callback and dismiss the composer:

然后处理委托回调并关闭作曲家：

- (void)mailComposeController:(MFMailComposeViewController*)controller didFinishWithResult:(MFMailComposeResult)result error:(NSError*)error
{
    //Add an alert in case of failure
    [self dismissViewControllerAnimated:YES completion:nil];
}

SWIFT 3:

快速 3：

Import the relevant library:

导入相关库：

import MessageUI

Mark your view controller as a delegate like so:

将您的视图控制器标记为委托，如下所示：

class MyViewController: UIViewController, MFMailComposeViewControllerDelegate {

Pull up composer (if user has email set up on their device):

拉起作曲家（如果用户在他们的设备上设置了电子邮件）：

@IBAction func emailButtonAction(_ sender: UIButton) {

        if MFMailComposeViewController.canSendMail() {
            let mail = MFMailComposeViewController()
            mail.mailComposeDelegate = self
            mail.setToRecipients(["[email protected]"])
            mail.setSubject("Example Subject")
            mail.setMessageBody("<p>Test</p>", isHTML: true)
            present(mail, animated: true)
        }
    }

Handle delegate callback and dismiss the composer:

处理委托回调并关闭作曲家：

func mailComposeController(_ controller: MFMailComposeViewController, didFinishWith result: MFMailComposeResult, error: Error?) {
    controller.dismiss(animated: true)
}
