英文:
MFMailComposeViewController delegate method not working in iOS 16.0 or above device when device orientation is in portrait mode
问题
我在另一个视图控制器的顶部显示了MFMailComposeViewController，而该视图控制器支持横向和纵向方向。以下是我尝试的方法：
if MFMailComposeViewController.canSendMail() {
let mc = MFMailComposeViewController()
mc.mailComposeDelegate = self
mc.setSubject(emailTitle)
mc.setMessageBody(messageBody, isHTML: false)
mc.setToRecipients(toRecipents)
mc.modalPresentationStyle = .fullScreen
// 展示MailComposeViewController
self.present(mc, animated: true)
}
这段代码完全正常工作，我还添加了类似以下的委托方法：
extension RateViewController: MFMailComposeViewControllerDelegate {
func mailComposeController(_ controller: MFMailComposeViewController, didFinishWith result: MFMailComposeResult, error: Error?) {
switch result {
case .cancelled:
print("邮件已取消")
case .saved:
print("邮件已保存")
case .sent:
print("邮件已发送")
case .failed:
print("邮件发送失败：\(error?.localizedDescription ?? "")")
default:
break
}
// 关闭邮件界面
controller.dismiss(animated: true) {
self.dismiss(animated: true)
}
}
}
我在多台iPhone设备上测试了这个代码，除了iOS 16.1.2设备之外，委托方法都正常调用。在iOS 16.1.2设备上，当设备处于横向方向时委托方法也能正常调用，但在纵向方向时却没有调用委托方法。这可能的原因是什么呢？
英文:
I present MFMailComposeViewController on top of another viewController and that viewController support both landscape and portrait orientation.
Here is the way I tried
if MFMailComposeViewController.canSendMail() {
let mc = MFMailComposeViewController()
mc.mailComposeDelegate = self
mc.setSubject(emailTitle)
mc.setMessageBody(messageBody, isHTML: false)
mc.setToRecipients(toRecipents)
mc.modalPresentationStyle = .fullScreen
// Present MailComposeViewController
self.present(mc, animated: true)
}
this work totally fine and also I added delegate method too like this
extension RateViewController: MFMailComposeViewControllerDelegate{
func mailComposeController(_ controller: MFMailComposeViewController, didFinishWith result: MFMailComposeResult, error: Error?) {
switch result {
case .cancelled:
print("Mail cancelled")
case .saved:
print("Mail saved")
case .sent:
print("Mail sent")
case .failed:
print("Mail sent failure: \(error?.localizedDescription ?? "")")
default:
break
}
// Close the Mail Interface
controller.dismiss(animated: true) {
self.dismiss(animated: true)
}
}
}
I tested this one in more than one iPhone devices, other than iOS 16.1.2 device delegate method call properly, in iOS 16.1.2 device it also calling properly when device in landscape orientation, for portrait orientation it is not call the delegate method. what can be the possible reason for this?

得分: 0
似乎是 iOS 版本 16.1.2 的一个 bug，在我更新那些设备后，它现在可以正常工作。

seems like it was a bug of iOS version 16.1.2 , after I update that devices now it works fine.
