I am trying to animate a UIImageView and then hide the image view after animation is complete. However the imageview gets hidden before the animation is completed. I looked at similar questions and they recommend implementing an animation listener or executing the. You can use a CATransaction to call a completion block after the animation completes.

As Paulw11 alluded to in his comment, you can use the animationDidStop: method mentioned in the docs. So in your shake method add a value-key pair to identify the animation and set the delegate to self, ex:. Then add the animationDidStop: delegate method to alert you as to when the animation is complete so you can start executing your code:.

Community and Moderator guidelines for escalating issues via new response….In a previous post about fade animations in Swift, I demonstrated how to use a class extension to add the ability for any UIView instance to easily call fadeIn or fadeOut on itself.

This strategy was nice — the animations, while simple, would have cluttered my code each time I used them, had I not encapsulated them somewhere. Employing class extensions in Swift seemed a natural way to provide this functionality to UIViews. For you, it may be something different that triggers the animation to begin. The real work all happens inside the UIViewExtensions. Next, I create a CATransition instance, and set its delegate property if a completionDelegate is passed when the function is called:.

Other properties that I set are durationtimingFunctionand fillMode :. This is probably the more challenging piece, just because it takes some tweaking to get the auto layout constraints just right. Next, I made sure that my label that will be sliding is inside the wrapper view. I set its constraints to.

If you specify a completionDelegate to the slideInFromLeft function, a method called animationDidStop will be called when the animation finishes. Hope this strategy is helpful for you as you think about where to place code for your UIView animations.By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

Animations in Swift (pt 2)

The dark mode beta is finally here. Change your preferences any time. Stack Overflow for Teams is a private, secure spot for you and your coworkers to find and share information.

The problem is that you're trying start the animation too early in the view controller's lifecycle. In viewDidLoadthe view has just been created, and hasn't yet been added to the view hierarchy, so attempting to animate one of its subviews at this point produces bad results. What you really should be doing is continuing to set the alpha of the view in viewDidLoad or where you create your viewsand then waiting for the viewDidAppear : method to be called.

At this point, you can start your animations without any issue. Compared to his solution I use DispatchQueue.

How can I add it in my view controller? UIKit stops ongoing animations if the app goes into inactive state. This could be fixed by observing application state and reactive animation if needed.

You have a very small window of opportunity to capture the attention of your users before your app ends up in the big black hole of obscurity. In this tutorial you will learn how to make such an animation.

Download the starter project for this tutorial heresave it to a convenient location and open it in Xcode. Open HolderView. In this UIView subclass, you will add and animate the following sublayers found in the Layers subgroup as shown in the animation above:. Open OvalLayer. Finally, open ViewController. This view will house all the animations. The view controller just needs to put it on the screen, and the view will take care of the actual animation code.

The animateLabel function is a delegate callback provided by the HolderView class that you will fill in as you complete the animation sequence. Build and run your app; you should see an empty white screen. An empty canvas — the perfect thing on which to start creating your new animations!

The animation starts with a red oval that expands into view from the centre of the screen and then wobbles around a bit. The starter project provides both of these Bezier paths for you. With your oval now expanding into view, the next step is to put some bounce in its step and make it wobble.

The beginTime of each subsequent animation is the sum of the beginTime of the previous animation and its duration. You repeat the animation group twice to give the wobble a slightly elongated feel. Go back to HolderView. Here you create a timer that calls wobbleOval right after the OvalLayer has finished expanding.

This declares a constant instance of TriangleLayerjust like you did for OvalLayer. Note: Finding the right duration or delay for animations takes some trial and error, and can mean the difference between a good animation and a fantastic one. I encourage you to tinker with your animations to get them looking perfect.

This method is called from the timer that you just added to wobbleOval. It calls the currently stubbed out method in triangleLayer which causes the triangle to animate. This code animates the corners of TriangleLayer to pop out one-by-one as the OvalLayer wobbles; the Bezier paths are already defined for each corner as part of the starter project.

The left corner goes first, followed by the right and then the top. Build and run the app to see the current state of the animation; as the oval wobbles, each corner of the triangle begins to appear until all three corners are visible, like so:.

This sets up a timer to fire after the triangle animation has finished. The 0. The timer you created just before adding this code calls this function once the the oval stops wobbling and all corners of the triangle appear.Open Xcode and create a new project by choosing the Single View Application template. Choose Swift as main language. Product Name is pretty self-explanatory. The organization name can be whatever you want, but it probably should the the company or name you are releasing your apps under.

The Organization Identifier is part of how your app will be referred to a bit more internally. This is part of how your iOS device determines whether an update to your app is the same app or a new one, by checking this Bundle Identifier.

The Language box gives you the choice of Objective-C or Swift. The next box has you select what devices this app should run on. You have the choice of iPhone, iPad, or Universal. Finally you can click that checkbox if you want Xcode to get some Core Data code ready for you. It would probably be best in the beginning at least not to, if only to let you see all of the moving parts of Core Data by having to set them up yourself.

When you click next, you will be presented with a save dialog, asking where you want to save your project. You also have the option to create a Git repository for your project either locally or on a server. You can download the class files from here.

Then we set the frame of the UIImageView to the frame of the view itself so as to make the image fill the total screen size. We then add the subView bg to the main view. Add the delegate as follows:. The code above uses the inbuilt animate function for the object button and a completion block which presents the SecondViewController as well as sets the transition delegate to self.

Now move on to the SecondViewController which will be presented on login button press.
