using UISaveVideoAtPathToSavedPhotosAlbum

On simulator UISaveVideoAtPathToSavedPhotosAlbum cannot save movie into photo album unless photo album is open. Can it? How can I check if Photo Album is running and run it silently from my app? Chances are that on a real iPhone/Pad it wi开发者_运维技巧ll be already running but just in case...?

My movie is in Resources of my app. I want to copy it to album. Here is the methods that I put in my AppDelegate.m to accomplish that:

 -(void)downloadVideo:(NSString *)sampleMoviePath{
if (UIVideoAtPathIsCompatibleWithSavedPhotosAlbum(sampleMoviePath)){
UISaveVideoAtPathToSavedPhotosAlbum(sampleMoviePath, self, @selector(video:didFinishSavingWithError: contextInfo:), sampleMoviePath);
}
}

-(void)video:(NSString *)videoPath didFinishSavingWithError:(NSError *)error contextInfo:(void *)contextInfo{
NSLog(@"Finished with error: %@", error);
}

I call it like this:

NSString *sampleMediaPathFromApp = [[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent:@"movie_01.m4v"];
[self downloadVideo:sampleMediaPathFromApp];

Error message that I get: Finished saving video with error: Error Domain=ALAssetsLibraryErrorDomain Code=-3310 "Data unavailable" UserInfo=0x564ab10 {NSLocalizedRecoverySuggestion=Launch the Photos application, NSLocalizedDescription=Data unavailable}

Naturally, if I open Photo album and then run my app it works fine.

Thanks a lot for your input. BG

I have edited the code so it is more readable - sorry I do not have an answer, but it is a good question - I had to put this here or else I could not submit the changes. --jwk82

You can save it as..

ALAssetsLibrary *assetLibrary = [[ALAssetsLibrary alloc] init];
[assetLibrary writeVideoAtPathToSavedPhotosAlbum:url completionBlock:^(NSURL *assetURL, NSError *error){
