This is sample code:
import UIKit
import MessageUI
class ViewController: UIViewController, MFMailComposeViewControllerDelegate {
@IBAction func showEmail(s
In addition to using .value
, don't forget to add to break
to each case
statement, see Apple's official version: https://developer.apple.com/library/iOS/samplecode/MessageComposer/Introduction/Intro.html#//apple_ref/doc/uid/DTS40010161
In swift 3, you can use this clear code:
@IBAction func sendMail(_ sender: Any) {
print(MFMailComposeViewController.canSendMail())
if MFMailComposeViewController.canSendMail() {
let mail = MFMailComposeViewController()
mail.mailComposeDelegate = self
mail.setToRecipients(["test@test.com"])
mail.setMessageBody("<p>This is test Mail!</p>", isHTML: true)
present(mail, animated: true)
} else {
let email = "test@test.com"
if let url = URL(string: "mailto:\(email)") {
UIApplication.shared.open(url)
}
}
}
func mailComposeController(_ controller: MFMailComposeViewController, didFinishWith result: MFMailComposeResult, error: Error?) {
controller.dismiss(animated: true)
switch result {
case .cancelled:
print("Mail cancelled")
case .saved:
print("Mail saved")
case .sent:
self.allertInfo(_title: "Mail Info", _message: "Mail is sent successfuly", _actionTitle: "OK")
print("Mail sent")
case .failed:
self.allertInfo(_title: "Mail Info", _message: "Mail isn't sent.",
_actionTitle: "OK")
print("Mail sent failure: \(error?.localizedDescription)")
default:
break
}
}
func allertInfo(_title:String, _message:String, _actionTitle:String) {
let alert = UIAlertController(title: _title, message: _message, preferredStyle: UIAlertControllerStyle.alert)
alert.addAction(UIAlertAction(title: _actionTitle, style: UIAlertActionStyle.default, handler: nil))
self.present(alert, animated: true, completion: nil)
}
I compared MFMailComposeResult
documentation on both Xcode 5 and Xcode 6.
In Swift, MFMailComposeResult
is a struct
struct MFMailComposeResult {
init(_ value: CUnsignedInt) // available in iPhone 3.0
var value: CUnsignedInt
}
with MFMailComposeResultCancelled
as a constant of type MFMailComposeResult
:
var MFMailComposeResultCancelled: MFMailComposeResult { get }
while it's an enum in Objective-C:
enum MFMailComposeResult {
MFMailComposeResultCancelled,
MFMailComposeResultSaved,
MFMailComposeResultSent,
MFMailComposeResultFailed
};
typedef enum MFMailComposeResult MFMailComposeResult; // available in iPhone 3.0
In order to make your code work, you will have to compare their values which are CUnsignedInt
.
So you will have to type the following code:
func mailComposeController(controller:MFMailComposeViewController, didFinishWithResult result:MFMailComposeResult, error:NSError) {
switch result.value {
case MFMailComposeResultCancelled.value:
println("Mail cancelled")
case MFMailComposeResultSaved.value:
println("Mail saved")
case MFMailComposeResultSent.value:
println("Mail sent")
case MFMailComposeResultFailed.value:
println("Mail sent failure: \(error.localizedDescription)")
default:
break
}
self.dismissViewControllerAnimated(false, completion: nil)
}
in Swift 2.0 do this:
func mailComposeController(controller: MFMailComposeViewController, didFinishWithResult result: MFMailComposeResult, error: NSError?) {
switch result.rawValue {
case MFMailComposeResultCancelled.rawValue:
print("Mail cancelled")
case MFMailComposeResultSaved.rawValue:
print("Mail saved")
case MFMailComposeResultSent.rawValue:
print("Mail sent")
case MFMailComposeResultFailed.rawValue:
print("Mail sent failure: \(error!.localizedDescription)")
default:
break
}
controller.dismissViewControllerAnimated(true, completion: nil)
}
In swift 3.0 -> Syntax Change
func mailComposeController(controller: MFMailComposeViewController,
didFinishWithResult result: MFMailComposeResult, error: NSError?) {
switch result.rawValue {
case MFMailComposeResult.Cancelled.rawValue:
print("Mail cancelled")
case MFMailComposeResult.Saved.rawValue:
print("Mail saved")
case MFMailComposeResult.Sent.rawValue:
print("Mail sent")
case MFMailComposeResult.Failed.rawValue:
print("Mail sent failure: %@", [error!.localizedDescription])
default:
break
}
// Dismiss the mail compose view controller.
controller.dismissViewControllerAnimated(true, completion: nil)
}
