如何从uiimagePicketController识别图像是截图还是相机图像？

Question

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingImage:(UIImage *)selectedImage editingInfo:(NSDictionary *)editInfo {
NSLog(@"done");

headingLabel.hidden= NO;
//[self playMovie];
[picker dismissViewControllerAnimated:YES completion:nil];
[self setupCroppingTool:selectedImage];

}

这是代码，所以如何识别selectedImage是截图或相机图像

Answer 1

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

此方法从照片库中选择image。您无法将screenshot image与normal image进行比较，因为它们都是UIImage。

Answer 2

可能会有所帮助..

我认为UIImagePickerController的源属性可以帮助您。

实施例

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

您可以使用其中之一..

UIImagePickerControllerSourceTypePhotoLibrary
UIImagePickerControllerSourceTypeCamera
UIImagePickerControllerSourceTypeSavedPhotosAlbum

Answer 3

查看图像元数据 - 日期，关键字，地理位置......并进行比较。
