我正在尝试使用 ReplayKit 录制我的应用，然后为用户提供共享或删除录制内容的选项。删除工作正常，但我无法让共享部分正常工作。我尝试将RPPreviewViewControllerMode与.shared一起使用，但XCode无法识别它。我还尝试过UIActivityViewController，它确实会弹出共享菜单 - 但是，如果我尝试访问录音，它不起作用。最后，我尝试了previewControllerDelegate，它允许用户编辑和保存视频，但不能共享它。
我在下面发布了我的代码。请指教，谢谢！

也许是因为.automatic模态演示，因为在iOS 13中，当您弹出控制器时，它不会覆盖全屏。所以，试试.fullScreen，它对我有帮助：
func stopRecording() {
recorder.stopRecording { (preview, error) in
guard preview != nil else {
print("Preview controller not available")
return
}
let alert = UIAlertController(title: "Recording finished", message: "Would you like to share or delete your recording?", preferredStyle: .alert
)
let deleteAction = UIAlertAction(title: "Delete", style: .destructive, handler: { (action) in
self.recorder.discardRecording {
print("Recording discarded successfully.")
}
})
let shareAction = UIAlertAction(title: "Share", style: .default, handler: { (action) in
// Try .fullScreen
preview?.modalPresentationStyle = .fullScreen
preview?.previewControllerDelegate = self
self.present(preview!, animated: true, completion: nil)
})
alert.addAction(deleteAction)
alert.addAction(shareAction)
self.present(alert, animated: true, completion: nil)
self.isRecording = false
self.viewReset()
}
}
