这是代码，所以如何识别selectedImage是截图或相机图像

3 个解决方案

#1

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingImage:(UIImage *)selectedImage editingInfo:(NSDictionary *)editInfo

This method picks the image from photo library. You cant compare a screenshot image with a normal image because both are UIImage.

此方法从照片库中选取图像。您无法将屏幕截图图像与普通图像进行比较，因为它们都是UIImage。

May be help..

可能会有所帮助..

I think source property of UIImagePickerController help you.

我认为UIImagePickerController的source属性可以帮助你。

Example.

例。

UIImagePickerController *abc = [[UIImagePickerController alloc] init];;
abc.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;

You can use one of this..

你可以使用其中一个..

UIImagePickerControllerSourceTypePhotoLibrary
UIImagePickerControllerSourceTypeCamera
UIImagePickerControllerSourceTypeSavedPhotosAlbum

Look at the image metadata - date, keywords, geolocation... and compare that.

查看图像元数据 - 日期，关键字，地理位置......并进行比较。
