Question

这是一个Swift 2.0项目。我有一个MFMailComposeViewController按预期显示，但没有填充内容，并且不响应用户交互，但取消按钮除外。

发送按钮显示为灰色。没有文本字段响应用户触摸。

在iPhone 6+ iOS 8.4.1，Xcode 7.0b6上运行

我错过了什么？

以下是我使用的代码：

@IBAction func hitSendEmail(sender: AnyObject) {
    let emailTitle = "Title goes here"
    let emailBody = "Blah blah blah blah."
    let recipientAddress = "EMAILGOESHERE"

    mailViewController = MFMailComposeViewController()
    guard let mailvc = mailViewController else {
        return
    }
    mailvc.mailComposeDelegate = self
    mailvc.setSubject(emailTitle)
    mailvc.setMessageBody(emailBody, isHTML: false)
    mailvc.setToRecipients([recipientAddress])
    self.presentViewController(mailvc, animated: true) { () -> Void in
    }
}

func mailComposeController(controller: MFMailComposeViewController, didFinishWithResult result: MFMailComposeResult, error: NSError?) {
    if let vc = controller.presentingViewController {
        vc.dismissViewControllerAnimated(true, completion: { () -> Void in
            self.mailViewController = nil
        })
    }
}

Answer 1

SOLVED: Apparently it's a bug in Xcode 7.0b6.

I recompiled the app under Xcode 6.4 (after changing the 'guard' statement to an 'if let') and it runs without problem.

MFMailComposeViewController没有响应或填充
