我想使用
swift来实现应用内电子邮件.当我点击按钮时,会弹出电子邮件窗口.但是,我无法发送电子邮件.此外,点击取消删除草稿后,我无法返回到原始屏幕.
import UIkit import MessageUI class Information : UIViewController,MFMailComposeViewControllerDelegate{ var myMail: MFMailComposeViewController! @IBAction func sendReport(sender : AnyObject) { if(MFMailComposeViewController.canSendMail()){ myMail = MFMailComposeViewController() //myMail.mailComposeDelegate // set the subject myMail.setSubject("My report") //To recipients var toRecipients = ["lipeilin@gatech.edu"] myMail.setToRecipients(toRecipients) //CC recipients var ccRecipients = ["tzhang85@gatech.edu"] myMail.setCcRecipients(ccRecipients) //CC recipients var bccRecipients = ["tzhang85@gatech.edu"] myMail.setBccRecipients(ccRecipients) //Add some text to the message body var sentfrom = "Email sent from my app" myMail.setMessageBody(sentfrom,isHTML: true) //Include an attachment var image = UIImage(named: "Gimme.png") var imageData = UIImageJPEGRepresentation(image,1.0) myMail.addAttachmentData(imageData,mimeType: "image/jped",fileName: "image") //Display the view controller self.presentViewController(myMail,animated: true,completion: nil) } else{ var alert = UIAlertController(title: "Alert",message: "Your device cannot send emails",preferredStyle: UIAlertControllerStyle.Alert) alert.addAction(UIAlertAction(title: "OK",style: UIAlertActionStyle.Default,handler: nil)) self.presentViewController(alert,completion: nil) } } func mailComposeController(controller: MFMailComposeViewController!,didFinishWithResult result: MFMailComposeResult,error: NSError!){ switch(result.value){ case MFMailComposeResultSent.value: println("Email sent") default: println("Whoops") } self.dismissViewControllerAnimated(true,completion: nil) } }
