Question

Is it possible to save .caf file into the photo library ?

In my app, User can record their sound and can upload it to the remote server. So I want to know that is it possible to save recorded voice file into photo library so user can view the previously recorded sound files and upload it ?

I’ve tried to save the .caf using ALAssetsLibrary by :-

NSURL *url = [NSURL fileURLWithPath:[NSString stringWithFormat:@"%@/recordTest.caf",DOCUMENTS_FOLDER]];
ALAssetsLibrary *lib = [[ALAssetsLibrary alloc] init];

[lib writeVideoAtPathToSavedPhotosAlbum:url completionBlock:^(NSURL *assetURL, NSError *error){
        if (error) 
        {
            NSLog(@"%@",error);
        } 
        else 
        {

        }
        }];

but it generates error…

Error Domain=ALAssetsLibraryErrorDomain Code=-3302 “Invalid data”
UserInfo=0x184b80 {NSLocalizedRecoverySuggestion=Try with different
data, NSLocalizedFailureReason=There was a problem writing this asset
because the data is invalid and cannot be viewed or played.,
NSLocalizedDescription=Invalid data, NSUnderlyingError=0x1834a0
“Invalid data”}
