KeyboardLayoutGuide

Almost every iOS developer has at one point had to deal with handling the presence of the keyboard. This framework makes it super simple to deal with by creating two new layout guides, keyboardLayoutGuide and safeAreakeyboardLayoutGuide. Both are added to the UIView class through extensions. These can easily constraint to and are updated automatically if a keyboard is presented.

Installation

Swift Package Manager

As of Xcode 11 SPM integrates nicely with Xcode. This means that installing dependencies with Xcode support is super easy. To add the dependency using Swift Package Manager do the following steps:

1. Select the desired project and choose the Swift Packages tab of your project.
2. Tap on the + button.
3. Enter https://github.com/sanderrouk/KeyboardLayoutGuide onto the search bar and click next.
4. Choose the Version option leaving the selection on Up to Next Major option.
5. Click Next.
6. Click Finish.
7. Either create a separate file for it or add import KeyboardLayoutGuide in the file where you want to use it.

Carthage

1. Add github "sanderrouk/KeyboardLayoutGuide" ~> 1.0.0 project to your Cartfile.
2. Run $ carthage update --platform ios, this library does not support building for platforms other than iOS.
3. Do the additional steps required for carthage frameworks.
4. Either create a separate file for it or add import KeyboardLayoutGuide in the file where you want to use it.

Usage

KeyboardLayoutGuide works by simply extending UIKit's UIView class functionality by adding KeyboardLayoutGuides to it. These can be used the same way the default SafeAreaLayoutGuide can be.

        let greenView = UIView()
        greenView.translatesAutoresizingMaskIntoConstraints = false
        greenView.backgroundColor = .green

        view.addSubview(greenView)
        NSLayoutConstraint.activate([
            greenView.topAnchor.constraint(equalTo: view.safeAreaKeyboardLayoutGuide.topAnchor),
            greenView.leftAnchor.constraint(equalTo: view.safeAreaKeyboardLayoutGuide.leftAnchor),
            greenView.rightAnchor.constraint(equalTo: view.safeAreaKeyboardLayoutGuide.rightAnchor),
            greenView.bottomAnchor.constraint(equalTo: view.safeAreaKeyboardLayoutGuide.bottomAnchor),
        ])

        let redCircle = UIView()
        redCircle.translatesAutoresizingMaskIntoConstraints = false
        redCircle.backgroundColor = .red
        redCircle.layer.cornerRadius = 50

        view.addSubview(redCircle)
        NSLayoutConstraint.activate([
            redCircle.heightAnchor.constraint(equalToConstant: 100),
            redCircle.widthAnchor.constraint(equalToConstant: 100),
            redCircle.centerXAnchor.constraint(equalTo: view.centerXAnchor),
            redCircle.bottomAnchor.constraint(equalTo: view.keyboardLayoutGuide.bottomAnchor)
        ])

        let textField = UITextField()
        textField.translatesAutoresizingMaskIntoConstraints = false
        textField.placeholder = "Example Text"
        view.addSubview(textField)
        NSLayoutConstraint.activate([
            textField.centerXAnchor.constraint(equalTo: view.centerXAnchor),
            textField.centerYAnchor.constraint(equalTo: view.centerYAnchor)
        ])

        let tapRecognizer = UITapGestureRecognizer(target: self, action: #selector(redCircleTapped))
        redCircle.addGestureRecognizer(tapRecognizer)

Or if you use PinKit then you can keep to the same style as this framework brings the familiar syntax.

        let greenView = UIView()
        greenView.backgroundColor = .green

        view.addSubview(greenView)
        greenView.pinEdgesToSuperviewSafeAreaKeyboardEdges()

        let redCircle = UIView()
        redCircle.backgroundColor = .red
        redCircle.setDimensions(to: CGSize(width: 100, height: 100))
        redCircle.layer.cornerRadius = 50

        view.addSubview(redCircle)
        redCircle.alignAxisToSuperview(axis: .vertical)
        redCircle.pinEdge(toSuperviewKeyboardEdge: .bottom)

        let textField = UITextField()
        textField.placeholder = "Example Text"
        view.addSubview(textField)
        textField.centerInSuperview()

        let tapRecognizer = UITapGestureRecognizer(target: self, action: #selector(redCircleTapped))
        redCircle.addGestureRecognizer(tapRecognizer)

Roadmap

This framework is planned to be a part of the iOS PowerKit framework which is coming soon.
