Add the contents of Sources/TTParallaxOnboarding folder to your project.
Best way to understand how to use the library is to clone and open the example project.
-
Build your art view in a single container view but keep the slides organized into a horizontal stack view. See
OboardingViewin the example project. -
Create an
TTParallaxScrollVieweither from code using the interface builder. -
Add the art view to the scrollview
let onboardingView = OnboardingView()
scrollView.set(contentView: onboardingView, pageCount: 3)- Assign a depth to each of your layer view. The depth value needs to be betwen 0.0 and 1.0. The greater the value is the farther the object will look when scrolling. For example some distant mountains would be 0.9 and somehting just in front of the scene will be 0.0 (this will scroll at the same rate with the ScrollView).
self.scrollView.addParallax(to: onboardingView.rocket, depth: 0.4)
self.scrollView.addParallax(to: onboardingView.mountain, depth: 0.7)If you want something to reamin stationary assign it the value of 1.0.
