1. How to repeat the problem.

在使用chatbar的使用有约束警告，例如：在点击加号按钮弹出MoreView的时候，出现警告。

Unable to simultaneously satisfy constraints. Probably at least one of the constraints in the following list is one you don't want. Try this: (1) look at each constraint and try to figure out which you don't expect; (2) find the code that added the unwanted constraint or constraints and fix it. ( "<MASLayoutConstraint:0x1742ae2e0 LCCKChatBar:0x105b303e0.bottom == UIView:0x105e262a0.bottom - 271>", "<MASLayoutConstraint:0x1744b2c00 LCCKChatMoreView:0x105b3ba70.top == LCCKChatBar:0x105b303e0.bottom>", "<MASLayoutConstraint:0x1708a4920 LCCKChatMoreView:0x105b3ba70.top == UIView:0x105e262a0.bottom - 210>" )

2. Please help me in this way.

希望能消除警告
