ios - Swift 2 中的 messageComposeViewController 错误

Question

以下代码适用于 Swift 1.2。现在，我得到一个错误:

"Value of type MessageComposeResult has no member 'value'"

func messageComposeViewController(controller: MFMessageComposeViewController, didFinishWithResult result: MessageComposeResult) {
    switch (result.value) {
    case MessageComposeResultCancelled.value:
        print("Message was cancelled")
        self.dismissViewControllerAnimated(true, completion: nil)
    case MessageComposeResultFailed.value:
        print("Message failed")
        self.dismissViewControllerAnimated(true, completion: nil)
    case MessageComposeResultSent.value:
        print("Message was sent")
        self.dismissViewControllerAnimated(true, completion: nil)
    default:
        break;
    }
}

为了在 Swift 2 中查找消息的状态，我应该检查结果的哪个成员？

Answer 1

在 Swift 2 中，value 不存在于 result 中。

改为使用 result.rawValue。
