问题
Now the situation is illustrated in this image:

I have an app having multiple Xib files calling in one main Xib and its class. I have added expand and collapse view which works on particular xib expand and collapse subviews as required and reduces/Expands Height too.
This works well for one xib section when all tabs of xib files are collapsed and the second xib won't change its y-coordinates, but I'm having a white space between. I want to fix it.
Note: Every xib contains a class referring to it. The whole app won't use auto-resize.
How can I solve this?
