Following the release of iOS 7 (and iOS 8 as well), animation and motion effects became central to the design of apps from both Apple and 3rd party developers.
Not only are animations used to set your app apart, they can improve the overall user experience of your application. Facebook’s Paper also employs animations beautifully to add to the overall user experience of the app. Not only do animations add to the user experience of the app, but they could be what delights and impresses your users guaranteeing repeat usage instead of uninstalling the app for a better one from the App Store. There are numerous ways of including animations in your apps, some of them being by use of UIKit Dynamics, layer animations, view controller transitions or by using a third party library like the Facebook Pop library or JNWSpringAnimation framework.
The tutorial starts off with a summary of APIs used to animate views, and ends with some examples which show the use of some of the APIs in an app. Creating animations on your views is a matter of changing properties on them and letting UIKit animate them automatically.
For simple view animations, UIKit provides the following APIs that can be used to animate views on the screen. The first one takes two parameters – a value for the duration in seconds of the animation and a closure where you specify the properties you want changed.
The other two APIs are similar to the first, but they take extra parameters that add more configuration to the animation.
The third API takes an additional two parameters – the delay, which is the time to wait before the animation starts and options, a UIViewAnimationOptions constant, which indicates how you want to perform the animations. Instead of an animation that just moves along a path, UIKit will execute the different stages of the animation.
The above two methods are used together, the second getting nested in the first’s animations closure. The first method sets the overall configuration of the animation, like how long it takes, delay and its options. The relative start time and relative duration of each frame is a value between 0 and 1 that expresses the percentage time within the total duration of the animation.
View transitions are used when you want to add a new view to your view hierarchy or remove a view from the view hierarchy.
The second one is used to take one view from the view hierarchy and and place a new view in its place. We’ll now look at a few examples that use some of the above API calls to animate views in the given starter project.
Open the Assistant Editor, and make sure it is the ExampleIViewController.swift that appears next to the storyboard on the split screen.
In the ExampleIViewController.swift add the following method which is called before the view is presented on screen.
This moves the username and password fields just out of view and sets the alpha value of the button to 0 which makes it invisible. The above looks more interesting than a static presentation, but the views getting animated at the same time, doesn’t create that great an effect.
Run the app and the resulting animation has the views animating on screen at different times.
In login screens, when login fails, there is usually an animation that indicates to the user that login has failed.
The above changes the size of the login button when pressed and animates the action with a spring animation which will cause the button’s width to expand and bounce a little at the end before settling. In your app, you might need to replace the background image of a view automatically when some action happens. Using the entrance and exit animations in PowerPoint 2013, text and other objects can drop, flip, or fly onto or off of your slide.


Note that additional animation options are available on the submenus at the bottom of the Animations list. You can access additional Entrance and Emphasis effects at the bottom of the animations list.
Before you add any more effects, it's a good idea to rename all the objects on your slides. You can see in the image below that "Research the Company" has Dissolve In for the Entrance animation and Loop de Loop from the Motion Path list for the second effect. The Animation Pane makes it easy to combine effects and change the playing order of the animations.
The screen displays each object with animations in numbered, gray boxes, with multiple boxes denoting multiple animations. Once youa€™ve got the hang of how animations can work for you, youa€™re limited only by your imagination. Amazon Shop buttons are programmatically attached to all reviews, regardless of products' final review scores. PCWorld helps you navigate the PC ecosystem to find the products you want and the advice you need to get the job done. The next step is more difficult, as you will need to make sure the items you use are not licensed.
For great examples of how animations are used to improve UX, you should look at how Apple uses animations in their apps. You can download the starter project which is a Single View Application with a table view that lists the examples presented in the tutorial tutorial.
UIKit will take the original state of the view and create a smooth transition from that state to the end state according to what you specified in the animations closure.
The second takes a completion closure which you can use to either specify another animation that you want done after the first or you can do some cleanup of the UI, for example, removing a view from the view hierarchy once another view is animated onto the scene. Damping is a value from 0 to 1 that determines how much the view bounces towards the end of the animation. You can group different animations together that share some common properties, but still be able to control them separately.
You then define one or more of the second method(the frames) inside the animations closure to set the different stages of the animation. Select Example I in the list and you should see a Login screen of an app with the username and password fields and login button. You have liberty over the duration, but you shouldn’t set such a large number as to annoy your users when animations on your app seem to take too long. Looking at the code, you can see that after the first animation block, we set a delay on subsequent ones. This is sometimes done as a shake of the text fields or the login button, and a message that lets the user know that login has failed. You could do it in a way where an image immediately replaces another on the view, or you could slowly fade it in to create a nice transition.
Open ExampleIIIViewController.swift and add the following variable and functions to the file.
Applied judiciously, these motion effects can bring dynamism to your deck and make your message more powerful.
Look for slides that imply movement, change or progressiona€”menus, maps, and charts are prime candidatesa€”and keep it to about one-third of the total number of slides so it doesn't get distractingly busy. Youa€™ll quickly lose track of which text box is the title and which graphic is the clock if you try to rely on the generic default names.

You can use your own photos, or you can find sites online that offer pictures for public domain, non-profit, or personal use. To distinguish their apps from other apps, developers employed such features as animations and motion effects to make their apps stand out. For example, in the Photos app, when you select a photo from a collection, the photo expands out from the selected one and on closing it, it shrinks back to the selected photo.
This action, the fact that the article expands out from its thumbnail version, suggests that in doing the opposite, i.e. I will be using this when we get to the examples portion of the tutorial, instead of starting from scratch. If you don’t include it, you will not see them get animated onto the screen, instead they will just be shown in their final position. Effects are color-coded by typea€”green for Entrance animations, yellow for Emphasis, red for Exit, and blue for Motion Paths. To do this, select an object , then click the Format tab (note: the Format tab is visible onlyA when an object on the screen is selected). For instance, you could make the six menu items in our example presentation fade in one at a time, then add a second effect that makes all of them shimmer simultaneously once the full menu is displayed. Here, you can customize the animation's performance from the Timing group, or click the arrow beside the selected animation (highlighted in pink) and define the performance actions in the drop-down list.
Because the buttons are attached programmatically, they should not be interpreted as editorial endorsements. She is also working on building her own website, so she is learning to code, as well as working with photography and Microsoft Office.
This adds to the navigation of the app in that it lets you know exactly where you were, if browsing many pictures.
Instead of having them come onto the screen and just stop in place at the end, have them be spring-like and bounce a little before settling down. When you select an animation effect, PowerPoint immediately previews it so you can see what it does. Next, select Arrange > Selection Pane, and the Selection window opens with a list of all your animations. Set the start time, Timed animations work better for demos and sales presentations that run continuously at trade shows and sales conferences. Then, go back to your slide show and go to the slide you want it on, right click, and go paste image.
Here, animation is used to convey how the app works and even a first time user of the app would soon be able to make assumptions on its use and figure out its navigation without needing a tutorial. Also create an outlet for the login button named loginButton and an action for the same button and name it login. We then use a completion closure to set the image view’s image to the second image and we remove the second image view from the view hierarchy since it is no longer needed.
If you don't like it, click the object again, select a different effect, and it's replaced. If you want it to start vigorously, then set a larger value, if you want a smooth animation, then you can set the value to 0. And the last item on the menu, "Toot Your Own Horn," Fades In on entrance and then Fades Out on exit. Now, if you add more effects to any of the current objects, PowerPoint will use these names.
