如何将viewcontroller的屏幕截图附加到邮件中？我已经有了发送邮件的代码......

@IBAction func SendMail(sender: AnyObject) {
    let picker = MFMailComposeViewController()
    picker.mailComposeDelegate = self
    picker.setCcRecipients(["xx@xx"])
    picker.setSubject("xxx" + " " + itemName.text! + "-" + itemEtage.text! + "-" + itemRaum.text!)
    picker.setMessageBody("xx" + " " + itemNow.text! + " " + "xxx", isHTML: true)

    presentViewController(picker, animated: true, completion: nil)
}

亲爱的请参考以下代码

您可以将MFMailComposer与文件附件一起使用

使用MFMailComposeViewController在电子邮件正文中添加图像

 import MessageUI

func composeMail() {

    let mailComposeVC = MFMailComposeViewController()

    mailComposeVC.addAttachmentData(UIImageJPEGRepresentation(UIImage(named: "emailImage")!, CGFloat(1.0))!, mimeType: "image/jpeg", fileName:  "test.jpeg")

    mailComposeVC.setSubject("Email Subject")

    mailComposeVC.setMessageBody("<html><body><p>This is your message</p></body></html>", isHTML: true)

    self.presentViewController(mailComposeVC, animated: true, completion: nil)

}

作为附件提交

@IBAction func sendEmail(sender: UIButton) {
    //Check to see the device can send email.
    if( MFMailComposeViewController.canSendMail() ) {
        println("Can send email.")

        let mailComposer = MFMailComposeViewController()
        mailComposer.mailComposeDelegate = self

        //Set the subject and message of the email
        mailComposer.setSubject("Have you heard a swift?")
        mailComposer.setMessageBody("This is what they sound like.", isHTML: false)

        if let filePath = NSBundle.mainBundle().pathForResource("swifts", ofType: "wav") {
            println("File path loaded.")

            if let fileData = NSData(contentsOfFile: filePath) {
                println("File data loaded.")
                mailComposer.addAttachmentData(fileData, mimeType: "audio/wav", fileName: "swifts")
            }
        }
        self.presentViewController(mailComposer, animated: true, completion: nil)
    }
}

在UIView上创建一个可以截取屏幕截图的扩展程序：

extension UIView {
    func screenShot() -> UIImage {
        UIGraphicsBeginImageContextWithOptions(bounds.size, opaque, UIScreen.mainScreen().scale)
        let contextRef = UIGraphicsGetCurrentContext()
        CGContextTranslateCTM(contextRef, 0, 0)
        layer.renderInContext(contextRef!)
        let image = UIGraphicsGetImageFromCurrentImageContext()
        UIGraphicsEndImageContext()
        return image
    }
}

您可以在任何视图上使用此功能来创建屏幕截图。然后按照提供的其他答案发送电子邮件。

@Slevin你只需要将你拥有的图像（截图）附加到MFMailComposer对象

//imageObject is image object
var myData: NSData = UIImagePNGRepresentation(imageObject)
picker.addAttachmentData(myData, mimeType: "image/png", fileName: "image.png")

您可以使用以下代码将图像作为数据附加到MFMailComposer对象

Answer 4

迅速5： 超级简单。

首先创建UIImage变量：

var image1 = UIImage?

第二个创建简单的功能来保存屏幕截图：

func saveScreenShot() {
  let renderer = UIGraphicsImageRenderer(size: view.bounds.size)
  let pieImage = renderer.image { ctx in
     view.drawHierarchy(in: view.bounds, afterScreenUpdates: true)
    }
 }

现在更新您的邮件功能：

@IBAction func SendMail(sender: AnyObject) {
    saveScreenShot()
    let picker = MFMailComposeViewController()
    picker.mailComposeDelegate = self
    picker.setCcRecipients(["xx@xx"])
    picker.setSubject("xxx" + " " + itemName.text! + "-" + itemEtage.text! + "-" + itemRaum.text!)
    picker.setMessageBody("xx" + " " + itemNow.text! + " " + "xxx", isHTML: true)
    mailComposer.addAttachmentData(image1!.jpegData(compressionQuality: CGFloat(0.7))!, mimeType: "image/jpeg", fileName:  "test.jpeg")

    presentViewController(picker, animated: true, completion: nil)
}

Xcode swift发送带有屏幕截图的邮件？
