How to get photo creation date in objective c

Question

I am trying to get picture taken date while choosing picture from Photo Library in iPhone. I am using below code to do the same.

NSDictionary* fileAttribs = [[NSFileManager defaultManager] attributesOfItemAtPath:path error:nil];
NSDate *result = [fileAttribs fileCreationDate]; //or fileModificationDate

But it is showing current date and time.

Is there any way to get picture taken date while choosing picture from Photo library.

You can do it checking the metadata of the picture with ALAsset

Look for the key ALAssetPropertyDate

EDIT, complete code:

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {

    NSURL *url = [info objectForKey:@"UIImagePickerControllerReferenceURL"];

    ALAssetsLibrary* assetslibrary = [[ALAssetsLibrary alloc] init];
    [assetslibrary assetForURL:url
                   resultBlock:^(ALAsset *asset) {
                       NSDate *myDate = [asset valueForProperty:ALAssetPropertyDate];
                       NSLog(@"Date: %@", myDate);
                   } failureBlock:^(NSError *error) {
                       NSLog(@"Error");
                   }];

    [picker dismissViewControllerAnimated:YES completion:nil];

}

Please, check the docs, try it for yourself and if it doesn't work, come back with a specific question. – Odrakir Oct 17 '13 at 09:22
Okay I checked. My code is: NSURL *url=[NSURL URLWithString:fileUrl]; ALAssetsLibrary *lib = [[ALAssetsLibrary alloc] init]; //The key UIImagePickerControllerReferenceURL allows you to get an ALAsset, which then allows you to get metadata (such as the date the media was created) [lib assetForURL:url resultBlock:^(ALAsset *asset) { NSLog(@"created: %@", asset); } failureBlock:^(NSError *error) { NSLog(@"error: %@", error); }]; Output is: created: (null) – Shivomkara Chaturvedi Oct 17 '13 at 09:32

Get the url like this: NSURL* url = [info objectForKey:@"UIImagePickerControllerReferenceURL"]; – Odrakir Oct 17 '13 at 09:47
I cant do that because I am using phonegap.. I get url from phonegap plugin like below: file://localhost/Users/shivam/Library/Application%20Support/iPhone%20Simulator/6.1/Applications/3007041C-CEA0-4A8C-884D-91F8268542D4/tmp/cdv_photo_004.png – Shivomkara Chaturvedi Oct 17 '13 at 09:58
Then I can't help you. There must be something wrong with that url. – Odrakir Oct 17 '13 at 10:09

ALAssetsLibrary is deprecated, so with PHAsset:

#import <Photos/PHAsset.h>

Then:

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {

        NSURL *imageURL = [info valueForKey:UIImagePickerControllerReferenceURL];
        PHAsset *phAsset = [[PHAsset fetchAssetsWithALAssetURLs:@[imageURL] options:nil] lastObject];
        NSDate *date = [phAsset creationDate];
        UIImage *image = [info valueForKey:UIImagePickerControllerOriginalImage];

}
