我想用swift实现应用内邮件。当我单击该按钮时，会弹出电子邮件窗口。但是，我无法发送电子邮件。而且，点击取消-删除草稿后，我无法返回到原来的屏幕。
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, animated: true, 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)
}
}
最佳答案
因为你没有将当前 View Controller 设置为 myMail 的 mailComposeDelegate，所以 mailComposeController:didFinishWithResult 方法没有被调用.初始化 myMail 后，确保添加:
myMail.mailComposeDelegate = self
然后你就可以开始了
