[Cocos2d-x] Click blank to hide keyboard

 

 
 

 

The edit box of cocos2dx edit displays a keyboard, but it is not flexible. Click return to hide it. If you need to click the background outside the keyboard to hide the keyboard, it is much easier.

 

Method:

1. Comment two reurns under EGLView. mm to ensure that the click event can be sent to the bottom layer when the soft keyboard is displayed.

// WARNING: commented by Teng. Click the background to hide the soft keyboard.
// Return;
}

Int ids [IOS_MAX_TOUCHES_COUNT] = {0 };
Float xs [IOS_MAX_TOUCHES_COUNT] = {0.0f };
Float ys [IOS_MAX_TOUCHES_COUNT] = {0.0f };

Ids [I] = (int) touch;

2. Add processing in the bottom layer class: Display and hide the keyboard.
