Proper implementation of handleInputModeList in Custom Keyboard

阅读更多关于 Proper implementation of handleInputModeList in Custom Keyboard

A new API has been added in iOS 10 to present the list of other keyboards the user can switch to - the same list that appears when users long press the globe on a system keyboard.

As noted in the headers, one should add a target

My problem is write picture. I really need you help. Maybe inputAccessoryView, inputAccessoryViwController can be used, but I really have no idea. Thanks so much! You can adjust the height of your custom keyboard’s primary view using Auto Layout. By default, a custom keyboard is sized to match the system keyboard, according to screen size and device orientation.

The following code lines show how you might define and add such

问题 I'm working on a today view extension with some custom view elements which I don't set up in interface builder. Now I'm wondering where the right point in the lifecycle is to init the widget content.
