I have two button to get images and to get videos from device. For Image button i code like this

- (IBAction)btn_image:(id)sender{
UIImagePickerController *img=[[UIImagePickerController alloc]init];
img.delegate=self;
img.sourceType=UIImagePickerControllerSourceTypePhotoLibrary;

[self presentViewController:img animated:YES completion:nil];}

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info{

imgview.image=img;}

In this code shows only images.. but when i press btn_video then how can i see only videos from device and no images. I don't want to record video from camera. please give me code..

Answer 1

put this line in your button code :

UIImagePickerController *img = [[UIImagePickerController alloc] init];
        img.delegate = self;
        img.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
        img.mediaTypes = [[NSArray alloc] initWithObjects:(NSString *)kUTTypeMovie, nil];
        [self presentModalViewController:imagePicker animated:YES];

and Add Frameworks MobileCoreService

get Video from didFinishPickingMediaWithInfo :

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

        // Handle a movie capture
        if (CFStringCompare ((CFStringRef) mediaType, kUTTypeMovie, 0) == kCFCompareEqualTo)
        {
            [self dismissViewControllerAnimated:YES completion:Nil];
            NSString *moviePath = [[info objectForKey:UIImagePickerControllerMediaURL] path];

            if (UIVideoAtPathIsCompatibleWithSavedPhotosAlbum(moviePath))
            {
                UISaveVideoAtPathToSavedPhotosAlbum(moviePath, self,@selector(video:didFinishSavingWithError:contextInfo:), nil);
            }
        }
}

video delegate method :

-(void)video:(NSString*)videoPath didFinishSavingWithError:(NSError*)error contextInfo:(void*)contextInfo
{
    if (error)
    {
        UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Error" message:@"Video Saving Failed"
                                                       delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil];
        [alert show];
    }
    else
    {
        UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Video Saved" message:@"Saved To Photo Album"
                                                       delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil];
        [alert show];
    }
}
