Installation
CocoaPods
EFColorPicker is available through CocoaPods. To install it, simply add the following line to your Podfile:
pod 'EFColorPicker'
Carthage
You can use Carthage to install EFColorPicker
by adding that to your Cartfile:
github "EFPrefix/EFColorPicker"
Swift Package Manager
The Swift Package Manager is a tool for automating the distribution of Swift code and is integrated into the Swift compiler.
Once you have your Swift package set up, adding EFColorPicker as a dependency is as easy as adding it to the dependencies
value of your Package.swift
.
dependencies: [
.package(url: "https://github.com/EFPrefix/EFColorPicker.git", .upToNextMinor(from: "5.2.2"))
]
Use
- First, include EFColorPicker in your project:
import EFColorPicker
- Next, we can call EFColorPicker with pure code:
let colorSelectionController = EFColorSelectionViewController()
let navCtrl = UINavigationController(rootViewController: colorSelectionController)
navCtrl.navigationBar.backgroundColor = UIColor.white
navCtrl.navigationBar.isTranslucent = false
navCtrl.modalPresentationStyle = UIModalPresentationStyle.popover
navCtrl.popoverPresentationController?.delegate = self
navCtrl.popoverPresentationController?.sourceView = sender
navCtrl.popoverPresentationController?.sourceRect = sender.bounds
navCtrl.preferredContentSize = colorSelectionController.view.systemLayoutSizeFitting(
UILayoutFittingCompressedSize
)
colorSelectionController.delegate = self
colorSelectionController.color = self.view.backgroundColor ?? UIColor.white
colorSelectionController.setMode(mode: EFColorSelectionMode.all)
if UIUserInterfaceSizeClass.compact == self.traitCollection.horizontalSizeClass {
let doneBtn: UIBarButtonItem = UIBarButtonItem(
title: NSLocalizedString("Done", comment: ""),
style: UIBarButtonItemStyle.done,
target: self,
action: #selector(ef_dismissViewController(sender:))
)
colorSelectionController.navigationItem.rightBarButtonItem = doneBtn
}
self.present(navCtrl, animated: true, completion: nil)
Also we can use EFColorPicker in Storyboard:
if "showPopover" == segue.identifier {
guard let destNav: UINavigationController = segue.destination as? UINavigationController else {
return
}
if let size = destNav.visibleViewController?.view.systemLayoutSizeFitting(UILayoutFittingCompressedSize) {
destNav.preferredContentSize = size
}
destNav.popoverPresentationController?.delegate = self
if let colorSelectionController = destNav.visibleViewController as? EFColorSelectionViewController {
colorSelectionController.delegate = self
colorSelectionController.color = self.view.backgroundColor ?? UIColor.white
if UIUserInterfaceSizeClass.compact == self.traitCollection.horizontalSizeClass {
let doneBtn: UIBarButtonItem = UIBarButtonItem(
title: NSLocalizedString("Done", comment: ""),
style: UIBarButtonItemStyle.done,
target: self,
action: #selector(ef_dismissViewController(sender:))
)
colorSelectionController.navigationItem.rightBarButtonItem = doneBtn
}
}
}
You can control the visibility of color textField by change the isColorTextFieldHidden
property of EFColorSelectionViewController
, for example:
isColorTextFieldHidden: true | isColorTextFieldHidden: false | ||
---|---|---|---|
For more detail, please see the demo.
- Last but not the least, you should implement
EFColorSelectionViewControllerDelegate
so you can sense the color changes:
// MARK:- EFColorSelectionViewControllerDelegate
func colorViewController(colorViewCntroller: EFColorSelectionViewController, didChangeColor color: UIColor) {
self.view.backgroundColor = color
// TODO: You can do something here when color changed.
print("New color: " + color.debugDescription)
}
