swift - ImagePickerController 在设备和模拟器上返回 "image format with an unknown type"

Question

我遇到了以下错误代码:Creating an image format with an unknown type is an error。我已经看到了几个与此有关的线程，但是似乎没有一个可以解决我的问题。我做错了什么是我的代码

public func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {

    if let image = info[UIImagePickerControllerOriginalImage] as? UIImage {
        let data = UIImagePNGRepresentation(image)


    } else{
        print("Something went wrong")
    }

}

Answer 1

这可能是因为您没有打开可选的包装。

尝试更改此行:

let data = UIImagePNGRepresentation(image)

收件人:

let data = UIImagePNGRepresentation(image!)

希望对您有所帮助。
