ABKeyboardAccessory makes it easier to determine when a keyboard is being shown/dismissed for UITextViews and UITextFields. ABKeyboardAccessory subclasses UIView, and is implemented by setting the ABKeyboardView as the 'inputAccessory' for the desired UITextView/UITextField. ABKeyboardAccesoryDelegate provides methods which relay information about the current frame of the ABKeyboardAccessory view, where one can adjust UI depending on the keyboard appearance.

To run the example project, clone the repo, and run pod install from the Example directory first.

• Requires iOS 8.0 or later
• Requires Automatic Reference Counting (ARC)

ABKeyboardAccessory is available through CocoaPods. To install it, simply add the following line to your Podfile:

pod "ABKeyboardAccessory"

When looking to initialize an ABKeyboardAccessory, it is as simple as one line. In one line, the ABKeyboardAccessory is set as the 'inputAccessory' for the designated UITextView/UITextField, and the delegate is set as well.

self.textField.inputAccessoryView = [[ABKeyboardAccessory alloc] initWithDelegate:self];

After initialization, the second step is to utilize either one of the ABKeyboardAccessoryDelegate methods to adjust the offset of the UITextView/UITextField.

/// Called when the keyboard frame changes, and privides a listener for the ABKeyboardAccessory frame position changing. Useful if determining offset when textView/textField is not flush with bottom of screen.
- (void) accessoryOffsetDidChange:(CGFloat)yOffset {
    [self.view layoutIfNeeded];
    self.bottomOffset.constant = yOffset;
    
    [UIView animateWithDuration:0.001f animations:^{
        [self.view layoutIfNeeded];
    }];
}
/// Called when the keyboard frame changes, and privides a listener for the ABKeyboardAccessory vertical offset position changing
- (void) didMoveKeyboardWithFrame:(CGRect)frame {
    CGRect windowFrame = [[[UIApplication sharedApplication] keyWindow] frame];
    CGFloat yOffset = windowFrame.size.height - frame.origin.y;
    [self.view layoutIfNeeded];
    self.bottomOffset.constant = yOffset;
    [UIView animateWithDuration:0.001f animations:^{
        [self.view layoutIfNeeded];
    }];
}
