KeyboardDodger
KeyboardDodger is an iOS cocoapod that uses a constraint to move a view out of the way of the on-screen keyboard.
Installation
pod 'KeyboardDodger', '~> 1.0'Usage
KeyboardDodger attaches to a view and a constraint at the bottom of the view, and manipulates the constraint to keep it out of the way of the on-screen keyboard.
An example implementation:
class ViewController: UIViewController {
var bottomConstraint: NSLayoutConstraint?
var keyboardDodger: KeyboardDodger?
override func viewDidLoad() {
super.viewDidLoad()
if let bottomConstraint = bottomConstraint {
keyboardDodger = KeyboardDodger(view: view, constraint: bottomConstraint, delegate: self)
}
}
}
extension ViewController: KeyboardDodgerDelegate {
func keyboardDodger(_ keyboardDodger: KeyboardDodger, willUpdateConstraintWith transition: KeyboardDodgerTransition) {
print("Keyboard dodger will update constraint")
}
func keyboardDodger(_ keyboardDodger: KeyboardDodger, didUpdateConstraintWith transition: KeyboardDodgerTransition) {
print("Keyboard dodger did update constraint")
}
func keyboardDodger(_ keyboardDodger: KeyboardDodger, willResetConstraintWith transition: KeyboardDodgerTransition) {
print("Keyboard dodger will reset constraint")
}
func keyboardDodger(_ keyboardDodger: KeyboardDodger, didResetConstraintWith transition: KeyboardDodgerTransition) {
print("Keyboard dodger did reset constraint")
}
}
