## Usage

```objc
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
    TaskDetailViewController *detailViewController = segue.destinationViewController;
    detailViewController.task = sender;

    // create animator object with instance of modal view controller
    // we need to keep it in property with strong reference so it will not get release
    self.animator = [[ZFModalTransitionAnimator alloc] initWithModalViewController:detailViewController];
    self.animator.dragable = YES;
    self.animator.direction = ZFModalTransitonDirectionBottom;
    [self.animator setContentScrollView:detailViewController.scrollview];

    // set transition delegate of modal view controller to our object
    detailViewController.transitioningDelegate = self.animator;

    // if you modal cover all behind view controller, use UIModalPresentationFullScreen
    detailViewController.modalPresentationStyle = UIModalPresentationCustom;
}
```
###ScrollView
If you have scrollview in the modal and you want to dismiss modal by drag it, you need to set scrollview to ZFModalTransitionAnimator instance.
```objc
[self.animator setContentScrollView:detailViewController.scrollview];
```

###Direction
You can set that which direction will our modal present. (default is ZFModalTransitonDirectionBottom)
```objc
self.animator.direction = ZFModalTransitonDirectionBottom;
```
P.S. Now you can set content scrollview only with ZFModalTransitonDirectionBottom

## Requirements

## FAQ

### How can I show modal only part of view ?
The current ViewController's view still visible behind the modal, so you just set transparent color to background view.
