Question

错误是＆＃34;无法转换类型＆＃39; [AnyObject]＆＃39;预期参数类型＆＃39; [String]？＆＃39;＆＃34;。有谁知道如何解决这个问题？

   func send() {
    let picker = MFMailComposeViewController()
    picker.mailComposeDelegate = self
    picker.setSubject(subject.text!)
     //the code below is the reason I got error for
    picker.setToRecipients(Const.CONTACT_MAIL)
    picker.setMessageBody(body.text, isHTML: true)
    presentViewController(picker, animated: true, completion: nil)
}

Answer 1

setToRecipients期待一个字符串数组。 Apple文档提供了此示例

picker.setToRecipients(["address@example.com"])

Answer 2

如果Const.CONTACT_MAIL是一个字符串，那么你可以试试这个：

picker.setToRecipients([Const.CONTACT_MAIL])

这是因为它需要一个数组

我在Xcode7 for String上遇到错误
