iphone - 使用带有源类型相机的 UIImagePickerController 时，我必须将捕获的图像保存到相机胶卷吗？

Question

来自 UIImagePickerController 的文档:

When the user taps a button to pick a newly-captured or saved image or movie, or cancels the operation, dismiss the image picker using your delegate object. For newly-captured media, your delegate can then save it to the Camera Roll on the device. For previously-saved media, your delegate can then use the image data according to the purpose of your app.

所以这看起来像是我必须将捕获的图像保存到相机胶卷。这是真的？未完成拒绝原因？

Answer 1

不，当 UIImagePickerController 被关闭时，您不需要保存到相机胶卷。我已经在几个应用程序中这样做了。
