Stack Overflow for Teams is a private, secure spot for you and your coworkers to find and share information. I have a UIView, placed in the middle of the screen. When the user presses a button, I want it to move up near top of the screen as it shrinks to about a fifth of its size. But for some reason, that only scales the view. I have also tried to put this in the animateWithDuration:.
Joe's answer above does exactly as his GIF describes but it doesn't really answer your question since it translates then scales the view as opposed to both translating and scaling at the same time.
Your issue is that you're setting the view's transform in your animation block then immediately overwritting that value with another transform.
To achieve both translation and scale at the same time, you'll want something like this:. You can achieve basic UIView animation in several ways in Swift. Below code is just a simple approach How are we doing? Please help us improve Stack Overflow. Take our short survey.

You might need this type of animation for a loader, an onTap of a button, or whatever. Step 1 to 4: Create swift project, set up your storyboard, add constraints, and connect your outlets The steps to set up this project this is pretty much the same as the rotating UIViews post, so check it out first.
After that, you can just augment Step 5 to make your UIView pulse. If I were to just pass. Repeat as the only thing in optionsmy UIView would keep on growing from its original size to 1. Autoreverse will perform the reverse of the animation and help make the transitions be smoother. The completion block is nil because I want my UIView to animate forever.
Nobody would want their UIView to animate forever, but for this example why not? If I were to have the block be nil like in the code above, after 3 animation rounds the UIView would stop abruptly at size 1. Having self. You can get the storyboard project is in this repo.
Tools: Swift 2. This is the function that contains the animation. Starting animation when app loads self.In Prototyping iOS Animations in Swift I introduced the a range of block-based functions that UIKit provides to create tweened animations and how a simple animation can be programmatically altered with some random variation to create more complex scenes.
This alone can create an interesting range of animations, but is still only the tip of the iceberg of what Apple provides as tools for creating animations. This tutorial looks at some more animation functions that require a little bit more setting up to create, but once mastered opens up an even larger number of possibilities.
If you want to perform an animated transition between two views, Apple provides a handful of default animations that are easy to create with just a small bit of code.

So performing this animation requires a little bit of setting up. Lets set up all three views in the viewDidLoad function…. The animation block should typically include the removal of one view, and the addition of the view to the container that is replacing it.
This is because our IBAction function is set up with the expectation that the redSquare is the visible square, and this is only true the first time we tap the animate button. Another new addition in iOS 7, instead of creating an animation by interpolating between a start value to an end value, this method allows us to define an by as many sub-parts as we want. Using our familiar basic animation functions you could attempt to animate the transform property like so:.
To do the full rotation, lets break the animation into three parts, with each part rotating one third 2 of the way around:. Luckily, instead of assigning each keyframe manually, we can give iOS a bezier curve 3 and the keyframes needed will be generated automatically. This requires us to use more powerful animation features of iOS that are slightly more complicated, but not too hard once you get the general approach.
Lets set some more properties to the animation object that adds some randomness to how long the animation takes so that some of the squares will move faster than othersand at what position of the animation it starts so that they appear staggered. Another useful technique to know that also uses an curve it to animate how much of the curve is drawn.
This animation uses a very simple oval as a curve, but this technique can be applied to any curve at all. Tuples are one of the reasons I love another programming language called Haskell. Most programming languages are designed so that a variable contains a single object. Tuples allow us to create an ad-hoc data structure that contains two or more objects of our choice.
Splitting the animation into two halves is still potentially ambiguous since the rotation in degrees from 0 to could equally be achieved either by moving clockwise or anti clockwise. It might work to define the rotation as 0 to then to but since 0 and are equivalent you might end up with the rotation backtracking on itself.
Animations in Swift (pt 2)
For this animation I also added a random size for each fish, but instead of randomly adding variation to the speed of each fish I calculated the duration of each animation based off the size so that smaller fish take longer to complete one loop than the larger fish.
This helps create an illusion of depth and perspective since closer objects should appear to move faster.

CGPath anim.Animation can vastly improve user experience in an application. I love buttons that animate and give you the feeling that you are actually pressing something.
Here are a couple of ways of doing button animations in Swift - both of which utilise UIButton addTarget methods. If you are not using RxSwift or RxCocoa, this method should work just as well. The only downside is that you once a button becomes animatable, you have no way of making it un-animatable. This is my preferred method of making generic animations.
The benefit of using RxSwift is that you start and stop animating button presses - should you wish to - simply by disposing the DisposeBag that you pass in. It also avoids you having to objc expose your control event methods.
This bit of Rx revolves around mapping button events to an animation state. For all other touch events we want to animate back to the identity the default transform. For more info on how transforms work, check out this article by HackingWithSwift.
These transform mappings are both merged and subscribed to the animate transform function which simply calls the animateTransform function whenever a new event is received.Buttons are not only good for user navigation, but also an extremely important design element for any website.

On-trend pulse buttons using CSS animations, keyframes and box-shadow. It make use of CSS animations. First, create a keyframes sequence. In this case, we're using box-shadow. The box-shadow value spread-radius sets the expansion of the shadow effect. Then in the button CSS, invoke the animation property. The last value in the animation property is the animation-iteration-countwhich is set to infinite in Example 1.
In Example 2 it's set to 3 iterations, and in example 3, a single instance. While meant for multilingual purposes, the CSS writing-mode property can be exploited for design.

For more visualized example of pulse animation in iOS please, look at the image below. In this tutorial, we will learn how to create pulse animation using swift language in iOS will create exactly same screen as shown the exemplary image above.
Step 2: Open ViewController. Step 3: Open Main. You can grab a copy of the avatar assets from here. Step 7: Since, we are creating a circular pulse animation so for this we also need our object which acts as a pulse origin, to be circular too, in our case its avatar imageView.
So make UIImageView circular. Below is the code that creates pulse. In above code, we created a circular path using UIBezierPath, setting following parameters as 1 arc center of the circular path to zero initially though we will set center of our circular pat later on. As we are done with circular pathwe need to create a layer using CAShapeLayer class that will act as our pulse.
Assign the properties to layer object as shown in the code above and finally add the layer to our avatar UIImageView layer. This is required as our avatar UIImageView acts as origin of pulse. Lastly, add layer to the array too. The above code is self explanatory, if you have any concerns or doubts then please feel free to ask then in comments.
Skip to content. If you run the app, at this point then you will see only one circle. As all the circular layers are added on top of each other. To animate layer as pulse, we are required to add two type of animations to the layer. Below is the code that adds the above two animations to the layer The above code is self explanatory, if you have any concerns or doubts then please feel free to ask then in comments. If you run the app, you will see that pulse animation is working nicely, if not then please follow the steps again.
In this tutorial we learned how to create pulse animation in swift.
