UIViewController Animation ios? - ios

Question

Trying to create something like below in Objective-C, this is available in Swift.
I tried using bridging etc, to use this code with my Objective C project but it's having import issues.
In Objective-C I tried below things and partially it works for UIView, but I guess I need to add transitions to complete UIViewController.
What I tried
- (IBAction)menuButtonPressed:(id)sender
{
if ([self.delegate respondsToSelector:#selector(menuButtonPressed)]) {
[self.delegate menuButtonPressed];
}
if (!isVertical) {
[UIView animateWithDuration: 0.6
delay: 0.0
usingSpringWithDamping: 0.3
initialSpringVelocity: .8
options: 0
animations: ^
{
self.transform = CGAffineTransformTranslate(self.transform, -240, 0);
self.transform = CGAffineTransformRotate(self.transform, 90 * M_PI / 180);
self.transform = CGAffineTransformTranslate(self.transform, 240, 0);
}
completion:^(BOOL finished) {
isVertical = YES;
}
];
}else{
[UIView animateWithDuration: 0.45
delay: 0.0
usingSpringWithDamping: 0.44
initialSpringVelocity: .8
options: 0
animations: ^
{
self.transform = CGAffineTransformTranslate(self.transform, -240, 0);
self.transform = CGAffineTransformRotate(self.transform, -90 * M_PI / 180);
self.transform = CGAffineTransformTranslate(self.transform, 240, 0);
}
completion:^(BOOL finished) {
isVertical = NO;
}
];
}
}
Any inputs will be helpful.

Here is a very simple implementation that you can use to animate transitions between view controllers. You could basically use the same animation gist if you want to use it with UIViews.
let generateRandomColor: Void -> UIColor = {
let red = CGFloat(arc4random_uniform(255)) / 255.0
let green = CGFloat(arc4random_uniform(255)) / 255.0
let blue = CGFloat(arc4random_uniform(255)) / 255.0
return UIColor(red:red, green: green, blue: blue, alpha: 1)
}
class SlideAnimationController: NSObject, UIViewControllerAnimatedTransitioning {
let presenting: Bool
init(presenting: Bool) {
self.presenting = presenting
super.init()
}
func transitionDuration(transitionContext: UIViewControllerContextTransitioning?) -> NSTimeInterval {
return 0.5
}
func animateTransition(transitionContext: UIViewControllerContextTransitioning) {
let containerView = transitionContext.containerView()!
let fromView = transitionContext.viewForKey(UITransitionContextFromViewKey)!
let toView = transitionContext.viewForKey(UITransitionContextToViewKey)!
var animatingView: UIView
var initialTransform: CGAffineTransform
var finalTransform: CGAffineTransform
if presenting {
containerView.addSubview(toView)
animatingView = toView
initialTransform = CGAffineTransformMakeRotation(CGFloat(-M_PI_2))
finalTransform = CGAffineTransformIdentity
} else {
containerView.insertSubview(toView, belowSubview: fromView)
animatingView = fromView
initialTransform = CGAffineTransformIdentity
finalTransform = CGAffineTransformMakeRotation(CGFloat(-M_PI_2))
}
animatingView.layer.anchorPoint = CGPointMake(0, 0)
animatingView.frame = containerView.bounds
animatingView.transform = initialTransform
UIView.animateWithDuration(transitionDuration(transitionContext), delay: 0, usingSpringWithDamping: 0.6, initialSpringVelocity: 16, options: UIViewAnimationOptions.CurveLinear, animations: { () -> Void in
animatingView.transform = finalTransform
}) {
_ in
toView.layer.anchorPoint = CGPointMake(0.5, 0.5)
toView.frame = containerView.bounds
transitionContext.completeTransition(true)
}
}
}
class PresentedViewController: UIViewController {
override func viewDidLoad() {
super.viewDidLoad()
view.backgroundColor = generateRandomColor()
let tapGestureRecognizer = UITapGestureRecognizer(target: self,
action: "tapped")
view.addGestureRecognizer(tapGestureRecognizer)
}
func tapped() {
dismissViewControllerAnimated(true, completion: nil)
}
}
class TestViewController: UIViewController, UIViewControllerTransitioningDelegate {
override func viewDidLoad() {
super.viewDidLoad()
view.backgroundColor = generateRandomColor()
let tapGestureRecognizer = UITapGestureRecognizer(target: self,
action: "tapped")
definesPresentationContext = true
view.addGestureRecognizer(tapGestureRecognizer)
}
func tapped() {
let presentedViewController = PresentedViewController()
presentedViewController.modalPresentationStyle = UIModalPresentationStyle.CurrentContext
presentedViewController.transitioningDelegate = self
presentViewController(presentedViewController, animated: true, completion: nil)
}
func animationControllerForPresentedController(presented: UIViewController, presentingController presenting: UIViewController, sourceController source: UIViewController) -> UIViewControllerAnimatedTransitioning? {
return SlideAnimationController(presenting: true)
}
func animationControllerForDismissedController(dismissed: UIViewController) -> UIViewControllerAnimatedTransitioning? {
return SlideAnimationController(presenting: false)
}
}
