KeyboardDodger
KeyboardDodger 是一个 iOS Cocoapod，它使用约束将视图从屏幕键盘移开。
安装
pod 'KeyboardDodger', '~> 1.0'使用
KeyboardDodger 将其连接到一个视图和视图底部的约束，并通过操作该约束来保持其不在屏幕键盘的路径上。
一个示例实现
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")
}
}
