We may need keyboard infomation from keyboard notifications to do animation. However, the approach is complicated and easy to make mistakes. Even more, we need to handle the bug of system fire keyboard notifications.
But KeyboardMan will make it simple & easy.
另有中文介绍。
Swift 3.0, iOS 8.0
(Swift 2.3, use version 0.7.0)
import KeyboardMan
Do animation with keyboard appear/disappear:
let keyboardMan = KeyboardMan()
keyboardMan.animateWhenKeyboardAppear = { [weak self] appearPostIndex, keyboardHeight, keyboardHeightIncrement in
print("appear \(appearPostIndex), \(keyboardHeight), \(keyboardHeightIncrement)\n")
if let strongSelf = self {
strongSelf.tableView.contentOffset.y += keyboardHeightIncrement
strongSelf.tableView.contentInset.bottom = keyboardHeight + strongSelf.toolBar.frame.height
strongSelf.toolBarBottomConstraint.constant = keyboardHeight
strongSelf.view.layoutIfNeeded()
}
}
keyboardMan.animateWhenKeyboardDisappear = { [weak self] keyboardHeight in
print("disappear \(keyboardHeight)\n")
if let strongSelf = self {
strongSelf.tableView.contentOffset.y -= keyboardHeight
strongSelf.tableView.contentInset.bottom = strongSelf.toolBar.frame.height
strongSelf.toolBarBottomConstraint.constant = 0
strongSelf.view.layoutIfNeeded()
}
}
For more specific information, you can use keyboardInfo that KeyboardMan post:
keyboardMan.postKeyboardInfo = { [weak self] keyboardMan, keyboardInfo in
// TODO
}
Check the demo for more information.
Feel free to drag KeyboardMan.swift
to your iOS Project. But it's recommended to use Carthage (or CocoaPods).
