Usage

- (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;
    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.

如果你在modal中有scrollview,而且你想通过拖拽来让控制器消失,你需要将这个scrollview设置成ZFModalTransitionAnimator的实例变量.

[self.animator setContentScrollView:detailViewController.scrollview];

Direction

You can set that which direction will our modal present. (default is ZFModalTransitonDirectionBottom)

你可以设置这个动画从哪个方向上来呈现.(默认是从底部呈现)

self.animator.direction = ZFModalTransitonDirectionBottom;

P.S. Now you can set content scrollview only with ZFModalTransitonDirectionBottom

P.S. 现在,通过以上设置后,动画想过将会从底部开始呈现.
