IHKeyboardAvoiding

IHKeyboardAvoiding

An elegant solution for keeping any UIView visible when the keyboard is being shown

Requirements

	IHKeyboardAvoiding Version
Objective C	2.6.0
Swift	3.0.0 +

Description

IHKeyboardAvoiding will translate any UIView up when the keyboard is being shown, then return it when the keyboard is hidden.

Register an avoidingView(UIView) with IHKeyboardAvoiding; when the keyboard is shown, if the avoidingView's frame will be intersected by the keyboard, then it will move up just above the keyboard. When the keyboard is dismissed, the avoidingView is returned to its original position.

What sets IHKeyboardAvoiding apart from other keyboard avoiding solutions is that it doesn’t require placing your content in a UIScrollView. No scroll view is used. And it isn’t restricted to keeping UITextFields visible, with IHKeyboardAvoiding any UIView can avoid the keyboard

If Autolayout is used then the constraints are animated, otherwise a CGAffine translation is done.

Supported Features

• iPhone keyboard
• iPad docked keyboard
• iPad undocked keyboard
• iPad split keyboard
• landscape & protrait
• 3rd party keyboards
• Auto Layout
• AutoResizingMask (Springs & Struts)

How to install

Add this to your CocoaPods Podfile.

pod 'IHKeyboardAvoiding'

How to use

To set the avoiding view

KeyboardAvoiding.avoidingView = self.avoidingView

Put it in viewDidLoad() or viewDidAppear(_ animated: Bool) depending on your usage

If you’re unsure put it in viewDidAppear(_ animated: Bool)

If you need to set the avoidingView, or its properites, dynamically consider putting it in textViewShouldBeginEditing(_ textView: UITextView)

Optional methods
KeyboardAvoiding.setAvoidingView(self.avoidingView, withTriggerView: self.triggerView) Use this to set an avoidingView but have a different view that triggers the avoiding. If a triggerView’s frame will be intersected by the keyboard, then the avoidingView will be moved so that the triggerView is above the keyboard
KeyboardAvoiding.buffer The avoidingView will move if the keyboard is within buffer points of the triggerView’s frame. Default buffer is 0
KeyboardAvoiding.paddingForCurrentAvoidingView The padding to put between the keyboard and triggerView. Default padding is 0

Enable tap to dismiss the keyboard by simply changing any UIView to be an instance of KeyboardDismissingView in you nib/storyboard

IHKeyboardAvoiding vs UIScrollView solutions - Fight, fight!

UIScrollView pros:

• They’re quick n easy

IHKeyboardAvoiding pros:

• You dont have scrollviews littered throughout your app
• Having multiple scrollviews in your view heirarchy can cause problems
• When the keyboard hides, scrollviews dont always scroll back to their original position
• Scrollviews only scroll enough to keep the focused textfield visible
• IHKeyboardAvoiding provides control over which UIViews are visible when the keyboard appears
