SYEmailHelper

Easily detect installed email clients and allow the user to choose one when sending an email.

I use it to quickly add a "Contact me" feature in my apps. This will detect a list of SYEmailService, representing:

native in-app composer
third party apps
last resort: copy email address to clipboard, to let your user send via an unsupported app

If there are no items in the list the completion block is called with an error: SYEmailHelperErrorDomain, code SYEmailHelperErrorCode_NoServiceAvailable.

If the use selected a third party app that couldn't be opened an error will be generated too: SYEmailHelperErrorCode_CouldntOpenApp.

If a single supported service is available it will automatically be launched.

If multiple supported services are available an action sheet will be displayed.

You can:

disable the "copy to pasteboard" option
change the text for "copy to pasteboard" option
change the text for "cancel" option

Example:

    PasteboardEmailService.name = "Copy email address to pasteboard"

    EmailHelper.shared.showCopyToPasteBoard = true
    EmailHelper.shared.actionSheetTitle = "Which app you wanna use?"
    EmailHelper.shared.actionSheetMessage = "We support some third party apps, native email client and copying to clipboard if your favorite app is not supported"
    EmailHelper.shared.actionSheetCancelButtonText = "Meh..."

    EmailHelper.shared.presentActionSheet(
        address: emailField.text,
        subject: subjectField.text,
        body: bodyField.text,
        presentingViewController: self,
        sender: sender)
    { (canceled, service, error) in
        if (canceled) {
            self.completionLabel.text = "User cancelled"
        }
        else if let service = service, let error = error {
            self.completionLabel.text = String(format: "Service %@ encountered error: %@", service.name, error.localizedDescription)
        }
        else if let error = error {
            self.completionLabel.text = String(format: "Encountered error: %@", error.localizedDescription)
        }
        else if let service = service {
            self.completionLabel.text = String(format: "No error, used service %@", service.name)
        }
    }
