私は、次のエラー出力取得しています：私のUICollectionViewCell内のビューのすべてがあるmessageTextViewを除いて、以下の方法でプログラムによって作成され制約競合UICollectionVIew
The methods in the UIConstraintBasedLayoutDebugging category on UIView listed in <UIKit/UIView.h> may also be helpful.

\t Probably at least one of the constraints in the following list is one you don't want.
\t Try this:
\t \t (1) look at each constraint and try to figure out which you don't expect;
\t \t (2) find the code that added the unwanted constraint or constraints and fix it.
\t (Note: If you're seeing NSAutoresizingMaskLayoutConstraints that you don't understand, refer to the documentation for the UIView property translatesAutoresizingMaskIntoConstraints)

Will attempt to recover by breaking constraint

Make a symbolic breakpoint at UIViewAlertForUnsatisfiableConstraints to catch this in the debugger.
