i'm developing a mac app that requires email access
here's the code i've tried on ios
-(IBAction)Contact us:(id)sender {
//Email Subject
NSString *emailTitle = #"";
//Email Content
NSString *messageBody = #"";
//Email Address
NSArray *toRecipients =[NSArray arrayWithObject:#"info#mandarin-espeak.com"];
MFMailComposeViewController *mc = [[MFMailComposeViewController alloc] init];
mc.mailComposeDelegate = self;
[mc setSubject:emailTitle];
[mc setMessageBody:messageBody isHTML:YES];
[mc setToRecipients:toRecipients];
}
how can i do it on a mac app to open default email client

Answer 1

In MacOS you can easily send e-mails like this:
class SendEmail: NSObject {
static func send() {
let service = NSSharingService(named: NSSharingServiceNameComposeEmail)!
service.recipients = ["abc#dom.com"]
service.subject = "Vea software"
service.performWithItems(["This is an email for auto testing through code."])
}
}
Usage:
SendEmail.send()

I ended up going with an AppleScript solution. This is a one off app, not for the store, so I turned sandboxing off. I also added Privacy - AppleEvents Sending Usage Description to the info.plist and in the Hardened Runtime under Signing and Capabilities checked Apple Events
My email code, shouldn't be too hard to pan out my unique stuff:
func emailUser(_ thisUser:NSManagedObject) {
let dictSIPResponse = checkSIPforAppIdentifier("com.microsoft.Outlook")
if let bIsSIPEnabled = dictSIPResponse["isSIPEnabled"] as? Bool, let strSIPMessage = dictSIPResponse["sipMessage"] as? String{
if bIsSIPEnabled {
if let thisWriter = thisUser as? Writer, let strEmailAddress = thisWriter.email {
let outlookScript = """
if application "Outlook" is running then
tell application "Outlook"
set newMessage to make new outgoing message with properties {subject:"Hooray for automation"}
make new recipient at newMessage with properties {email address:{name:"Steve Suranie", address:"steven.suranie#xandr.com"}}
send newMessage
end tell
end if
"""
var out: NSAppleEventDescriptor?
if let scriptObject = NSAppleScript(source: outlookScript) {
var errorDict: NSDictionary? = nil
out = scriptObject.executeAndReturnError(&errorDict)
if let error = errorDict {
print(error)
}
}
}
} else {
print(strSIPMessage)
}
}
}
Before trying to email with the AppleScript I check to ensure the permissions have been set:
func checkSIPforAppIdentifier(_ sipIdentifier:String) -> Dictionary<String, Any> {
var dictSIPResponse = [String:Any]()
var targetAppEventDescriptor = NSAppleEventDescriptor(bundleIdentifier: sipIdentifier)
var status = AEDeterminePermissionToAutomateTarget(targetAppEventDescriptor.aeDesc, typeWildCard, typeWildCard, true);
switch (status) {
case -600: //procNotFound
dictSIPResponse["isSIPEnabled"] = false
dictSIPResponse["sipMessage"] = "Not running app with id \(sipIdentifier)"
break;
case 0: // noErr
dictSIPResponse["isSIPEnabled"] = true
dictSIPResponse["sipMessage"] = "SIP check successfull for app with id \(sipIdentifier)"
break;
case -1744: // errAEEventWouldRequireUserConsent
// This only appears if you send false for askUserIfNeeded
dictSIPResponse["isSIPEnabled"] = false
dictSIPResponse["sipMessage"] = "User consent required for app with id \(sipIdentifier)"
break;
case -1743: //errAEEventNotPermitted
dictSIPResponse["isSIPEnabled"] = false
dictSIPResponse["sipMessage"] = "User didn't allow usage for app with id \(sipIdentifier)"
// Here you should present a dialog with a tutorial on how to activate it manually
// This can be something like
// Go to system preferences > security > privacy
// Choose automation and active [APPNAME] for [APPNAME]
default:
break;
}
return dictSIPResponse
}
