## 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.
