You can use ALAsset library, it contain the property called ALAssetPropertyDate. So using that you can fetch the date like that below:-
NSURL *url = @"your url";
ALAssetsLibrary* assetslibrary = [[ALAssetsLibrary alloc] init];
[assetslibrary assetForURL:url
resultBlock:^(ALAsset *asset) {
NSDate *myDate = [asset valueForProperty:ALAssetPropertyDate];
NSLog(@"Date: %@", myDate);
} failureBlock:^(NSError *error) {
NSLog(@"Error");
}];
