EatFit

Check this article on our blog.

Purpose

Eat fit is a component for attractive data representation inspired by Google Fit. It is based on PageViewController, interface for customization is implemented in UITableViewDataSource style.

Supported OS & SDK Versions

• Swift 5
• iOS 9.0+
• Xcode 11

ARC Compatibility

EatFit requires ARC.

Supported orientations

EatFit supports only portrait orientation.

Thread Safety

EatFit is subclassed from UIView and - as with all UIKit components - it should only be accessed from the main thread. You may wish to use threads for loading or updating EatFit contents or items, but always ensure that once your content has loaded, you switch back to the main thread before updating the EatFit.

Installation

Carthage

github "Yalantis/EatFit" ~> 3.0

Manual

To install manually the EatFit component in an app, drag EatFit folder with all contents into your project. Use EatFitViewController as any other view controller in your app. Setup is done via data source pattern. EatFitViewController's data source must adopt protocol EatFitViewControllerDataSource

Memory issues

Inside the component pages are reused just like cells in UITableView. There are no more than 3 pages exist in memory at any moment no matter how many pages the component shows.

Properties

The EatFit has following properties:

	weak var dataSource: EatFitViewControllerDataSource!

Methods

The EatFitViewController class has the following methods:

	func reloadData()

This reloads all the component from the dataSource and refreshes the display.

Data source protocol

The EatFitViewControllerDataSource protocol has the following methods:

    func numberOfPagesForPagingViewController(controller: EatFitViewController) -> Int

Returns the number of pages in the EatFit view controller.

    func chartColorForPage(index: Int, forPagingViewController controller: EatFitViewController) -> UIColor

Returns the tint color for specific page. Tint color defines the chart color and logo color.

    func percentageForPage(index: Int, forPagingViewController controller: EatFitViewController) -> Int

Returns the percentage that defines displayed value of the percentage label and the graphic chart.

    func titleForPage(index: Int, forPagingViewController controller: EatFitViewController) -> String

Returns the title that is displayed at the top of each page.

    func descriptionForPage(index: Int, forPagingViewController controller: EatFitViewController) -> String

Returns the description that is displayed at the bottom of each page.

    func logoForPage(index: Int, forPagingViewController controller: EatFitViewController) -> UIImage

Returns the image for specific page. Actual color of image doesn't matter, it will be colored with page tint color. Perhaps keep in mind that image must be png with opacity.

    func chartThicknessForPagingViewController(controller: EatFitViewController) -> CGFloat

Returns chart thickness in points. It is applied for all pages.

Let us know!

We’d be really happy if you send us links to your projects where you use our component. Just send an email to [email protected] And do let us know if you have any questions or suggestion regarding the animation.

P.S. We’re going to publish more awesomeness wrapped in code and a tutorial on how to make UI for iOS (Android) better than better. Stay tuned!
