Set the maximum recording duration while video recording from the iphone app

In my iPhone app, user can record video. I want to set the maximum allowed recording time to 30 seconds. How to do this, any ideas?

with this code

-(BOOL)startCameraControllerFromViewController:(UIViewController*)controller
                             usingDelegate:(id )delegate {
   if (([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera] == NO)
    || (delegate == nil)
    || (controller == nil)) {
    return NO;
   }
   UIImagePickerController *cameraUI = [[UIImagePickerController alloc] init];
  cameraUI.sourceType = UIImagePickerControllerSourceTypeCamera;
 cameraUI.mediaTypes = [[NSArray alloc] initWithObjects:(NSString *)kUTTypeMovie, nil];

cameraUI.allowsEditing = NO;
cameraUI.delegate = delegate;

[controller presentModalViewController: cameraUI animated: YES];
return YES;
 }

-(void)imagePickerController:(UIImagePickerController *)picker  didFinishPickingMediaWithInfo:(NSDictionary *)info {
 NSString *mediaType = [info objectForKey: UIImagePickerControllerMediaType];
[self dismissModalViewControllerAnimated:NO];
  if (CFStringCompare ((__bridge_retained CFStringRef) mediaType, kUTTypeMovie, 0) == kCFCompareEqualTo) {
    NSString *moviePath = [[info objectForKey:UIImagePickerControllerMediaURL] path];
    NSLog(@"movie path %@",moviePath);


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

-(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];
   }
  }

You need to set the videoMaxiumDuration property to the UIImagePickerController after setting it to record video.



The value is an NSTimeInterval which is in seconds, so you want to set it to 300 seconds if you want 5 minutes of video.
