objective c - MFMailComposeViewController in Swift -

this sample code:

import uikit import messageui class viewcontroller: uiviewcontroller, mfmailcomposeviewcontrollerdelegate { @ibaction func showemail(sender : anyobject) { var emailtitle = "test email" var messagebody = "this test email body" var torecipents = ["a.nakhimov@gmail.com"] var mc: mfmailcomposeviewcontroller = mfmailcomposeviewcontroller() mc.mailcomposedelegate = self mc.setsubject(emailtitle) mc.setmessagebody(messagebody, ishtml: false) mc.settorecipients(torecipents) self.presentviewcontroller(mc, animated: true, completion: nil) } override func viewdidload() { super.viewdidload() // additional setup after loading view, typically nib. } override func didreceivememorywarning() { super.didreceivememorywarning() // dispose of resources can recreated. } func mailcomposecontroller(controller:mfmailcomposeviewcontroller, didfinishwithresult result:mfmailcomposeresult, error:nserror) { switch result { case mfmailcomposeresultcancelled: nslog("mail cancelled") case mfmailcomposeresultsaved: nslog("mail saved") case mfmailcomposeresultsent: nslog("mail sent") case mfmailcomposeresultfailed: nslog("mail sent failure: %@", [error.localizeddescription]) default: break } self.dismissviewcontrolleranimated(false, completion: nil) }

}

in function mailcomposecontroller error on every case expression:

could not find overload '~=' accepts supplied arguments.

what doing wrong?

i compared mfmailcomposeresult documentation on both xcode 5 , xcode 6. in swift, mfmailcomposeresult struct

struct mfmailcomposeresult { init(_ value: cunsignedint) // available in iphone 3.0 var value: cunsignedint }

with mfmailcomposeresultcancelled constant of type mfmailcomposeresult:

var mfmailcomposeresultcancelled: mfmailcomposeresult { }

while it's enum in objective-c:

enum mfmailcomposeresult { mfmailcomposeresultcancelled, mfmailcomposeresultsaved, mfmailcomposeresultsent, mfmailcomposeresultfailed }; typedef enum mfmailcomposeresult mfmailcomposeresult; // available in iphone 3.0

in order create code work, have compare values cunsignedint.

so have type next 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) }
