我已经在TableView中创建了设置页。当我点击行0时，将调用活动视图控制器。当我点击row2时，MailComposeController被调用。
调用了MailComposeController，但当我点击邮件屏幕上的“取消”或“发送”按钮时，它不起作用。
这是密码
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
if indexPath.row == 0 {
let message = "Hey download my app [LINK]"
let shareView = UIActivityViewController(activityItems: [message], applicationActivities: nil)
self.present(shareView, animated: true, completion: nil)
} else if indexPath.row == 1 {
let mailCompose = MFMailComposeViewController()
mailCompose.mailComposeDelegate = self
mailCompose.setToRecipients(["[email protected]"])
mailCompose.setSubject("feedback")
mailCompose.setMessageBody("text", isHTML: false)
if MFMailComposeViewController.canSendMail()
{
self.present(mailCompose, animated: true, completion: nil)
}
else{
print("error...!")
}
}
func mailComposeController(_ controller: MFMailComposeViewController, didFinishWith result: MFMailComposeResult, error: Error?) {
controller.dismiss(animated: true, completion: nil)
}
最佳答案
您必须将delegate方法放在ViewController中，而不是放在tableView:didSelectRowAt方法中：
extension ViewController: MFMailComposeViewControllerDelegate {
func mailComposeController(_ controller: MFMailComposeViewController, didFinishWith result: MFMailComposeResult, error: Error?) {
controller.dismiss(animated: true, completion: nil)
}
}
