Save a Video that I record in my app

问题

I am succeeding in understanding how to make a camera app in my learning journey:-)

The only thing I am stuck with is saving a video that I have recorded. I am able to save a photo, but the same does not work for videos.

So I think I have almost got it with the help of iBrad Apps.

got this code:

-(void)imagePickerController:(UIImagePickerController *)picker
   didFinishPickingMediaWithInfo:(NSDictionary *)info
 {
NSString *mediaType = [info objectForKey:UIImagePickerControllerMediaType];

[self dismissModalViewControllerAnimated:YES];

if ([mediaType isEqualToString:(NSString *)kUTTypeImage]) {
    UIImage *image = [info 
                      objectForKey:UIImagePickerControllerOriginalImage];

    imageView.image = image;

    if (newMedia)
        UIImageWriteToSavedPhotosAlbum(image, 
                                       self,
                                       @selector(image:finishedSavingWithError:contextInfo:),
                                       nil);
}
else{

    if ([mediaType isEqualToString:(NSString *)kUTTypeMovie]) {
        UIImage *movie = [info 
                          objectForKey:UIImagePickerControllerQualityTypeHigh];

        videoRecorder2.image = movie;

            if (newMedia)
                UISaveVideoAtPathToSavedPhotosAlbum(movie, 
                                               self,
                                               @selector(movie:finishedSavingWithError:contextInfo:),
                                               nil);
}}}

I have an if statement because the app can take both video and still images.

The first part is for still - which works and then the second part I am still tutu-ing with:-)

Try this:

UISaveVideoAtPathToSavedPhotosAlbum(moviepath,nil,nil,nil);

Edit: Try this and modify your code to this method:

// For responding to the user tapping Cancel.
- (void) imagePickerControllerDidCancel: (UIImagePickerController *) picker {

    [[picker parentViewController] dismissModalViewControllerAnimated: YES];
    [picker release];
}

// For responding to the user accepting a newly-captured picture or movie
- (void) imagePickerController: (UIImagePickerController *) picker
            didFinishPickingMediaWithInfo: (NSDictionary *) info {

    NSString *mediaType = [info objectForKey: UIImagePickerControllerMediaType];
    UIImage *originalImage, *editedImage, *imageToSave;

    // Handle a still image capture
    if (CFStringCompare ((CFStringRef) mediaType, kUTTypeImage, 0)
            == kCFCompareEqualTo) {

        editedImage = (UIImage *) [info objectForKey:
                    UIImagePickerControllerEditedImage];
        originalImage = (UIImage *) [info objectForKey:
                    UIImagePickerControllerOriginalImage];

        if (editedImage) {
            imageToSave = editedImage;
        } else {
            imageToSave = originalImage;
        }

    // Save the new image (original or edited) to the Camera Roll
        UIImageWriteToSavedPhotosAlbum (imageToSave, nil, nil , nil);
    }

    // Handle a movie capture
    if (CFStringCompare ((CFStringRef) mediaType, kUTTypeMovie, 0)
            == kCFCompareEqualTo) {

        NSString *moviePath = [[info objectForKey:
                    UIImagePickerControllerMediaURL] path];

        if (UIVideoAtPathIsCompatibleWithSavedPhotosAlbum (moviePath)) {
            UISaveVideoAtPathToSavedPhotosAlbum (
                    moviePath, nil, nil, nil);
        }
    }

    [[picker parentViewController] dismissModalViewControllerAnimated: YES];
    [picker release];
}
