当我通过UIImagePickerController选择图像时,我在xCode中得到以下输出:
发现扩展时遇到[discovery]错误:Error Domain = PlugInKit Code = 13“query canceled”UserInfo = {NSLocalizedDescription = query canceled}
这是我的代码:
func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
let image = info[UIImagePickerControllerOriginalImage] as! UIImage
imagePicked = image
dismiss(animated: true, completion: nil)
performSegue(withIdentifier: "showImage", sender: self)
}
ViewController类声明为:
class ViewController: UIViewController, UIImagePickerControllerDelegate, UINavigationControllerDelegate {
let imagePickerController = UIImagePickerController()
var imagePicked = UIImage()
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
imagePickerController.delegate = self
}
我使用按钮打开ImagePicker:
@IBAction func chooseImageBtn(_ sender: Any) {
imagePickerController.sourceType = .photoLibrary
self.present(imagePickerController, animated: true, completion: nil)
}
当我在模拟器中启动应用程序时,我可以单击按钮,然后选择一个图像,然后选择器关闭,此消息显示在Xcode中:

我已经做了一些研究,但没有任何效果。 ImagePicker的委托设置为self
,我也尝试在@objc
之前添加func imagePickerController(_ picker:
,但这并没有解决问题。
我还可以尝试显示所选图像?
答案 0 :(得分:1)
尝试删除performeSegue
功能,如果您确实需要使用它,只需将其添加到completion
功能的dismiss
即可。
