jopen 9年前發布 | 10K 次閱讀 iOS開發移動開發 DAExpandAnimation

DAExpandAnimation 是一個自定義的模式切換，提供一個有拉伸效果的控件。

Usage

Try the example project!

Have your view controller conform to UIViewControllerTransitioningDelegate. Optionally set thecollapsedViewFrame, theexpandedViewFrameand theanimationDuration.

private let animationController = DAExpandAnimation()

override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
    if let toViewController = segue.destinationViewController as? UIViewController, selectedCell = sender as? UITableViewCell {
        toViewController.transitioningDelegate = self
        toViewController.modalPresentationStyle = .Custom
        toViewController.view.backgroundColor = selectedCell.backgroundColor

        animationController.collapsedViewFrame = {
            return selectedCell.frame
        }
        animationController.animationDuration = Constants.SomeAnimationDuration

        if let indexPath = tableView.indexPathForCell(selectedCell) {
            tableView.deselectRowAtIndexPath(indexPath, animated: false)
        }
    }
}

func animationControllerForPresentedController(presented: UIViewController, presentingController presenting: UIViewController, sourceController source: UIViewController) -> UIViewControllerAnimatedTransitioning? {
    return animationController
}

func animationControllerForDismissedController(dismissed: UIViewController) -> UIViewControllerAnimatedTransitioning? {
    return animationController
}
