実際にxibを使用してカメラアプリケーションを統合しました。ビューにuiviewを配置した後、imageviewを配置し、トリミングのためにimageviewに再度表示します。次に、このエラーが発生したプロジェクトを実行します。
2013-07-23 12:45:49.936 Camera_App1[30668:907] 制約を同時に満たすことができません。おそらく、次のリストの制約の少なくとも 1 つが望ましくないものです。これを試してみてください: (1) 各制約を見て、どれが予期しないものかを把握してみてください。(2) 不要な制約を追加したコードを見つけて修正します。(注: 理解できない NSAutoresizingMaskLayoutConstraints が表示されている場合は、UIView プロパティ translatesAutoresizingMaskIntoConstraints のドキュメントを参照してください)

Break on objc_exception_throw to catch this in the debugger.
The methods in the UIConstraintBasedLayoutDebugging category on UIView listed in <UIKit/UIView.h> may also be helpful.

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. (Note: If you're seeing NSAutoresizingMaskLayoutConstraints that you don't understand, refer to the documentation for the UIView property translatesAutoresizingMaskIntoConstraints)
