A bunch of tools, cocoa subclasses and extensions we created and use at Ackee.

Installation

Carthage

You can also use Carthage. Specify this repo in your Cartfile:

github "AckeeCZ/ACKategories" ~> 6.15.0

SPM

Or you can use SPM. Add this to your Package.swift:

.package(url: "https://github.com/AckeeCZ/ACKategories.git", .upToNextMajor(from: "6.15.0")),

Swift versions

If you're interested in using ACKategories in your older projects see all branches, there probably is the version you need.

List of features

This is only fast description of features, see source code for documentation comments and details.

Flow coordinators

ACKategories contain basic FlowCoordinator that should be used as parent class for all your flow coordinators. For more information see FlowCoordinators.

UIButton

Extension for UIButton that fixes intrinsicContentSize and adds titleEdgeInsets to it.

UIColor

• Initialize colors with hex codes
• Create random color
• Create lighter/darker colors from color
• Recognize light/dark background colors to decide what text color you should use.
• Create solid color image from color.

UIControl

Add action blocks to UIControls.

let button = UIButton()
button.on(.touchUpInside) { sender in
    ...
}

If running on iOS 9 or later you can use implicit parameter UIControl.primaryActionTriggered.

String

• trim strings easily
• get first letter of string
• simplify localization

Collections

• isEmpty on optional collections (even strings). Returns true when collection is nil or empty.

TableHeaderFooterView

Use this view as TableHeaderView or TableFooterView when your table/footer has dynamic content size.

GradientView

Use this view when you want to create a view with gradient colors and a given axis.

Init takes two parameters:

• colors: The colors to be used for the gradient.
• axis: The axis of the gradient: .vertical for bottom-to-top gradient, .horizontal for left-to-right gradient.

Please note: If one of your colors is clear, you should usually define to which "clear color" it should go to - i.e. if you want to go from white to clear, write:

let gradientView = GradientView(colors: [UIColor.white, UIColor.white.withAlphaComponent(0)], axis: .vertical)

UITableView and UICollectionView extensions

Since now you can use simple extension which autoregisters your UITableView and UICollectionView cells!

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
    // generically dequed cell which was autoregistered, no need to register your cells in advance
    let cell: YourCustomCell = tableView.dequeCellForIndexPath(indexPath)
    return cell
}

And it's the same story with UICollectionView.

Forking this repository
