Show presenting view controller with partial curl - ios

Question

I have a view controller with several textfields/text views and would like to allow the user to populate these fields with things they find on the web. To allow this I have a different web view presented modally. My problem is that I would like to use a partial page curl to display the first view controller (with any populated information). However, you can't present a live view controller a second time, and the new instance is not pre populated with whatever information was already placed in the textfields.
It seems like I could just pass that information back and forth (from the first instance, to the second view controller, then copy the info into the second instance, then copy back when I dismiss the second instance, etc) but it seems like there should be a better way.
I could also just add the web view controller as a subview, but I miss the functionality of the partial curl, which I really like.
Thanks!

However, you can't present a live view controller a second time, and
the new instance is not pre populated with whatever information was
already placed in the textfields.
You dont need to create a new view controller each time. Just store that view controller object as an instance variable and dont release it until your user is done.
if (myViewController == nil) {
myViewController = [UIViewController alloc] init];
}
[self presentViewController:myViewController animated:YES];

So I've kind of combined the comments and the posted answer.
First: I store an instance of the vc with the web view and add its view to the first view controller and then hide the view:
self.webVC = [self.storyboard instantiateViewControllerWithIdentifier:#"webView"];
self.webVC.delegate = self;
self.webVC.view.frame = self.view.bounds;
[self.view addSubview:self.webVC.view];
[self.webVC.view didMoveToSuperview];
self.findPoemVC.view.hidden = YES;
Then I used a category on UIView to uncurl and curl the view. I found the code here:
To show the view I perform a CurlDown animation like this:
self.findPoemVC.view.hidden = NO;
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:1.0];
[UIView setAnimationTransition:UIViewAnimationTransitionCurlDown
forView:self.webVC.view
cache:YES];
self.webVC.view.hidden = NO;
[UIView commitAnimations];
On the webVC I implemented a protocol and implement the delegate methods in the first view controller:
In the webVC:
#protocol PoemFinderDelegate <NSObject>
-(void)shouldUncurl;
-(void)doneWasPressed;
#end
The delegate was set earlier (see above) and the implementation of the delegate methods to partially uncurl and totally uncurl the webview were done like this inside the first view controller:
-(void)shouldUncurl{
[self.webVC.view animationPartialCurlUp];
}
-(void)doneWasPressed{
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:0.50];
[UIView setAnimationTransition:UIViewAnimationTransitionCurlUp
forView:self.webVC.view
cache:YES];
self.webVC.view.hidden = YES;
[UIView commitAnimations];
}
