MFMailComposeViewController() 未在 UIAlertAction 中被解除
MFMailComposeViewController() not dismissed inside UIAlertAction
我在 UIAlertController 中打开了 MFMailComposeViewController,代码如下所示:
import StoreKit
import MessageUI
class SettingsListViewController: UIViewController, MFMailComposeViewControllerDelegate, UINavigationControllerDelegate {
// Some code adding the UITableView and etc
// ...
}
private extension SettingsListViewController {
func didSelectShareCell(shareSectionCell: ShareSectionCell, _ tableView: UITableView, cellForRowAt indexPath: IndexPath) {
switch shareSectionCell {
// Some other cases...
case .rate:
let actionSheet = UIAlertController(title: "Feedback", message: "Are you enjoing the app?", preferredStyle: .alert)
actionSheet.addAction(UIAlertAction(title: "Dismiss", style: .cancel, handler: nil))
actionSheet.addAction(UIAlertAction(title: "Yes, i love it", style: .default, handler: { action in
SKStoreReviewController.requestReview()
}))
actionSheet.addAction(UIAlertAction(title: "No, this sucks", style: .default, handler: { action in
guard MFMailComposeViewController.canSendMail() else {
// Alert info user
return
}
let composer = MFMailComposeViewController()
composer.mailComposeDelegate = self
composer.delegate = self
composer.setToRecipients(["my mail"])
composer.setSubject("i'm mad")
composer.setMessageBody("Hey, i love your app but...", isHTML: false)
self.present(composer, animated: true)
func mailComposeController(_ controller: MFMailComposeViewController,
didFinishWith result: MFMailComposeResult, error: Error?) {
self.dismiss(animated: true)
}
}))
present(actionSheet, animated: true)
}
}
}
一切正常。发送邮件 window 打开,邮件也被发送了,但是当按下 'cancel' 和 'send' 按钮时,MFMailComposeViewController() 没有被关闭(必须按顺序向下滑动关闭它)
有什么问题吗?
将此委托置于函数之外并置于控制器内class。
另外,像这样解散controller.dismiss(animated: true)
private extension SettingsListViewController {
func mailComposeController(_ controller: MFMailComposeViewController,
didFinishWith result: MFMailComposeResult, error: Error?) {
controller.dismiss(animated: true)
}
}
