iOS - Moving file to video folder

Question

I have a app which takes a movie and saves it to the apps temp folder after the video is completed i need to move it to video folder on the device.... How would this be accomplished using Default File manager ?

Source code i found.... and if i save the file in the documents directory am will i be able to access it from Video app on iPhone?

NSFileManager *fileManager = [NSFileManager defaultManager];
NSError *error;
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];

NSString *txtPath = [documentsDirectory stringByAppendingPathComponent:@"txtFile.txt"];

if ([fileManager fileExistsAtPath:txtPath] == NO) {
    NSString *resourcePath = [[NSBundle mainBundle] pathForResource:@"txtFile" ofType:@"txt"];
    [fileManager copyItemAtPath:resourcePath toPath:txtPath error:&error];
}

NSDocumentDirectory is sandboxed for every iOS app. The API you are looking for is UISaveVideoAtPathToSavedPhotosAlbum.

For example:

UISaveVideoAtPathToSavedPhotosAlbum(videoPath, nil, nil, nil);
