I'm trying to build an app in which I'm able to capture image with camera and save to gallery. But I'm unable to get the file name of image. If I select image from camera roll, then I'm able to get file name of selected image.But when I capture image with camera in my app, It returns file name "null
". Here is my code to save and select image from gallery using UIImagePickerController
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
UIImage *chosenImage = [self scaleAndRotateImage:[info valueForKey:UIImagePickerControllerOriginalImage]];
NSString *mediaType = info[UIImagePickerControllerMediaType];
self.userProfileImage.image = chosenImage;
if ([mediaType isEqualToString:(NSString *)kUTTypeImage]) {
UIImage *image = info[UIImagePickerControllerOriginalImage];
if (newMedia)
UIImageWriteToSavedPhotosAlbum(image,
self,
@selector(image:finishedSavingWithError:contextInfo:),
nil);
}
imageRotation=[NSString stringWithFormat:@"%f %f %f",acos (self.userProfileImage.transform.a), asin (self.userProfileImage.transform.b), atan2(self.userProfileImage.transform.b, self.userProfileImage.transform.a)];
CGFloat angle = [(NSNumber *)[self.userProfileImage valueForKeyPath:@"layer.transform.rotation.z"] floatValue];
NSLog(@"%f", angle);
NSURL *referenceURL = [info objectForKey:UIImagePickerControllerReferenceURL];
ALAssetsLibrary *assetLibrary = [ALAssetsLibrary new];
[assetLibrary assetForURL:referenceURL
resultBlock:^(ALAsset *asset) {
ALAssetRepresentation *assetRep = [asset defaultRepresentation];
fileName = [assetRep filename];
NSLog(@"File name = %@", fileName);
}
failureBlock:^(NSError *error) {
NSLog(@"%@", error);
}];
[[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleLightContent];
[[UIApplication sharedApplication] setStatusBarHidden:YES];
[picker dismissViewControllerAnimated:YES completion:nil];
imageChanged=TRUE;
}
And this code to save captured image
- (void)image:(UIImage *)image didFinishSavingWithError:(NSError *)error contextInfo:(void *)contextInfo {
UIAlertView *alert;
//NSLog(@"Image:%@", image);
if (error) {
alert = [[UIAlertView alloc] initWithTitle:@"Error!"
message:[error localizedDescription]
delegate:nil
cancelButtonTitle:@"OK"
otherButtonTitles:nil];
[alert show];
}
}
I'm stuck at the point that how can I get file name of captured image. What wrong I'm doing in my code ? Please suggest me any correction or solution. Any help would be appreciated . Thanks in advance
Here is how I get file name of a file, video or photo, which picked with UIImagePickerController:

The image you have taken is not saved and has not any name yet. You need to save the image before you can get the path for the image. That´s why it returns nil.
