-Technically IQKeyboardManager moves upwards/downwards of currently presentedViewController's view. So if you're pinning your textfield from topLayoutGuide then you're saying **Keep x distance from screen top(I don't care about where is self.view)**'. In this case your view is moved upwards but textField remains at same position and keeping x distance from screen top. Here is the screenshot of bad Autolayout configuration(If using IQKeyboardManager) with topLayoutguide.

+ To fix it, just let IQKeyboardManager know the constraint which is pinned with **TopLayoutGuide/BottomLayoutGuide**, just map **TopLayoutGuide/BottomLayoutGuide** constraint with **IQLayoutGuideConstraint**. Here is the screenshot:-

 #### Disable for a ViewController:-
 
  If you would like to disable `IQKeyboardManager` for a particular ViewController then register ViewController with `-(void)disableInViewControllerClass:(Class)disabledClass` method in AppDelegate.([#117](https://github.com/hackiftekhar/IQKeyboardManager/issues/117),[#139](https://github.com/hackiftekhar/IQKeyboardManager/issues/139))
