MLInputDodger

           

My library does not seek any reward, but if you use this library, star it if you like. :)

Advantage

• Automatic processing of keyboard-related events with little code, not affect global and no special view or viewController nee to be inherited, so it's flexible.
• Provide a optional default retractButton which can be clicked to hide keyboard.
• Use animateAlongsideBlock to add your own dodge behaviors for other views or to trigger other behaviors.
• With transition complete of two vc, the dodge behavior would be triggered again, ensure dodge behavior.
• Fixed iOS8's bug: UIKeyboardFrameEndUserInfoKey return strange origin.y sometimes.
• Fixed SougouInput's bug: it produces a ungly spring animation sometimes.

Principle

• The dodgeView means which view need to be change frame or change contentOffset(contentInset)
• All subviews which can becomeFirstResponder in the dodgeView will trigger the dodge behavior.
• The inputView of subviews maybe not only keyboard. It's ok, this is why the library named MLInputDodger not MLKeyboardDodger. :)

Usage

- (void)viewDidAppear:(BOOL)animated
{
    [super viewDidAppear:animated];
    
    self.view.shiftHeightAsDodgeViewForMLInputDodger = 50.0f;
    [self.view registerAsDodgeViewForMLInputDodgerWithOriginalY:self.view.frame.origin.y];
}

Then the subviews which can becomeFirstResponder will trigger dodge.
If you need custom shiftHeight for special responder, just set the shiftHeightAsFirstResponderForMLInputDodger property.

Disbale default retract input accessory view:

self.view.dontUseDefaultRetractViewAsDodgeViewForMLInputDodger = NO; //for all subviews of self.view

self.testView1.dontUseDefaultRetractViewAsFirstResponderForMLInputDodger = NO; //for sepecial

AnimateAlongside:

[[MLInputDodger dodger]setAnimateAlongsideBlock:^(BOOL show,UIView *dodgerView,UIView *firstResponderView,CGRect inputViewFrame) {
        if ([dodgerView isKindOfClass:[UIScrollView class]]) {
            ((UIScrollView*)dodgerView).scrollIndicatorInsets = ((UIScrollView*)dodgerView).contentInset;
        }
    }];

__weak __typeof(self)weakSelf = self;
    [self.tableView setAnimateAlongsideAsDodgeViewForMLInputDodgerBlock:^(BOOL show,UIView *dodgerView,UIView *firstResponderView,CGRect inputViewFrame) {
        __strong __typeof(weakSelf)sSelf = weakSelf;
        CGRect frame = sSelf.testAnimateAlongsideLabel.frame;
        if (show) {
            frame.origin.y = inputViewFrame.origin.y+kMLInputDodgerRetractViewDefaultHeight-kLabelBottomMargin-kLabelHeight;
        }else{
            frame.origin.y = sSelf.view.frame.size.height-kLabelBottomMargin-kLabelHeight;
        }
        sSelf.testAnimateAlongsideLabel.frame = frame;
    }];

Tips

You can add this category to disable automatic keyboard for UITableViewController, or it will affect the implementation of the library. But _adjustForAutomaticKeyboardInfo:animated:lastAdjustment: is a private api, so...

@implementation UITableView(DisableAutomaticKeyboard)
- (void)_adjustForAutomaticKeyboardInfo:(id)arg1 animated:(BOOL)arg2 lastAdjustment:(float*)arg3 {
    return;
}
@end
