Now you need to figure out how to animate this gradient. Add the line of code below to the end of didMoveToWindow(): layer.addSublayer(gradientLayer)īuild and run your project you should see the app display the exact gradient you’re looking for: You can have as many key points and color milestones as you like, but the text gradient animation in this chapter only needs the simple black-white-black gradient shown above.Īdd the following code to layoutSubviews() to give the gradient a frame: ame = boundsĪll that you need to do now is add the gradient to the view’s layer to see it in action. This sets up the gradient color milestones as follows: Add the following code below: let locations: = [ You can also specify where exactly in the gradient’s frame these colors should appear. The gradient above starts with a black color, blends to white, and finally blends back to black. Now add the following code to define the colors that build up the gradient after the code you just added: let colors = [ ![]() This defines the orientation of the gradient and its start and end points. GradientLayer.endPoint = CGPoint(x: 1.0, y: 0.5) GradientLayer.startPoint = CGPoint(x: 0.0, y: 0.5) Add the following code to AnimatedMaskLabel.swift inside the gradientLayer property code after the comment shown below: // Configure the gradient here You’ll first draw the base gradient of AnimatedMaskLabel. You’ll work with this class throughout this chapter to add gradient animations.īuild and run your project you’ll see just the faux clock appear at the top of the screen: The bottom view is an instance of AnimatedMaskLabel that’s included with the starter project. There’s a static label on top that mimics the iPhone clock on the lock screen and another view near the bottom. Open the starter project for this chapter and select Main.storyboard to see how the UI looks at present: You’ll have to work through this chapter, however, to see what this cool effect is!Īs an extra bonus, you’ll learn how to create a layer mask out of a piece of text and use it to mask a gradient. You’ll animate the gradient for a “Slide to reveal” label and then reveal a cool mystery effect when the user swipes over the label. In this chapter you’ll learn how to mimic this effect with a moving gradient and how to animate the colors and layout of those gradients: While it is no longer a part of iOS, one of the nicest was a simple little animation: the “slide to unlock” label on the lock screen.
