An elegant solution for keeping any UIView visible when the keyboard is being shown
IHKeyboardAvoiding will translate any UIView up when the keyboard is being shown, then return it when the keyboard is hidden.
Two views are registered with IHKeyboardAvoiding, the 'avoiding' UIView which is moved, and one or more 'target' UIViews which will be kept visible above the keyboard. If a target view's frame will be intersected by the keyboard, then the avoiding view will move up, keeping the target view just above the keyboard.
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, instead any UIView can be a target which will be kept visible
If Autolayout is used then the constraints are animated, otherwise a CGAffine translation is done.
- iPhone keyboard
- iPad docked keyboard
- iPad undocked keyboard
- iPad split keyboard
- landscape & protrait
- 3rd party keyboards
- autolayout
- traditional layout
Add this to your CocoaPods Podfile.
pod 'IHKeyboardAvoiding'
To set the avoiding view
[IHKeyboardAvoiding setAvoidingView:(UIView *)avoidingView with:(UIView *)targetView];
To add another target
[IHKeyboardAvoiding addTarget:(UIView *)targetView];
Parameters
(UIView *)avoidingView
The view to move above, usually the background view
(UIView *)targetView
If a targetView's frame will be intersected by the keyboard, then the avoidingView will be moved so that the targetView is above the keyboard.
Optional methods
(BOOL)isKeyboardVisible
A convenience method to check if the keyboard is visible
(void)setBuffer:(int)buffer
The avoidingView will move if the keyboard is within [buffer] points of the targetView's frame. Default buffer is 0
(void)setPadding:(int)buffer
The padding to put between the keyboard and target view. Default padding is 0
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
