ios - 如何使用 Segue 从 didFinishPickingMediaWithInfo 发送 UIImage？
<p><p>所以我有什么:</p>
<pre><code>func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info:) {
let tempImage: UIImage = info as! UIImage
let imagetoTransmit: UIImage = tempImage
shootedImage = imagetoTransmit
self.performSegue(withIdentifier: "cameraSegueIdent", sender: nil)
dismiss(animated: true, completion: nil)
}
</code></pre>
<p>哪里转:</p>
<pre><code> override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
if segue.identifier == "cameraSegueIdent" {
let imageToTransmit: UIImage = shootedImage
let viewController = (segue.destination as! TakenPhotoPreviewViewController)
viewController.takenImage = imageToTransmit
}
}
</code></pre>
<p>图像正在发送，但 Segue 没有执行。<br/>请帮助!</p>
<p><strong>更新</strong></p>
<p>我的想法是将图像作为发送者发送，而不保存在当前的 ViewController 中，它就像一个魅力!</p>
<pre><code>func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info:) {
let tempImage: UIImage = info as! UIImage
self.dismiss(animated: true) {
self.performSegue(withIdentifier: "cameraSegueIdent", sender: tempImage)
}
}
</code></pre></p>
<br><hr><h1><strong>Best Answer-推荐答案</ strong></h1><br>
<p><p>以下可能会有所帮助。</p>
<pre><code> let tempImage: UIImage = info as! UIImage
let imagetoTransmit: UIImage = tempImage
shootedImage = imagetoTransmit
_ picker.dismissViewControllerAnimated(true, completion: {
self.performSegue(withIdentifier: "cameraSegueIdent", sender: nil)
})
</code></pre>
<p>另外，请确保在 Storyboard中正确配置了 segue 标识符。</p></p>
