Невозможно одновременно удовлетворить ограничениям при открытии камеры

Question

У меня есть приложение, которое использует веб-просмотр для отображения некоторых HTML-форм. В HTML-формах добавлена ​​возможность выбора изображения с устройства. Вся функциональность из HTML-формы для захвата изображения. Когда я нажимаю кнопку обзора формы из камеры веб-просмотра, открывается, и все работает нормально, но я получаю ниже регистрацию xcode.

Snapshotting a view that has not been rendered results in an empty snapshot. Ensure your view has been rendered at least once before snapshotting or snapshot after screen updates. 
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. (Note: If you're seeing NSAutoresizingMaskLayoutConstraints that you don't understand, refer to the documentation for the UIView property translatesAutoresizingMaskIntoConstraints) 
(
    "<NSLayoutConstraint:0x16fa21f0 UIView:0x180afaa0.height == 0.454545*CAMModeDial:0x16f06760.height - 4.09091>", 
    "<NSLayoutConstraint:0x18065020 CAMShutterButton:0x180bfbc0.centerY == CAMBottomBar:0x16f06100.centerY>", 
    "<NSLayoutConstraint:0x18065b70 V:[CAMShutterButton:0x180bfbc0]-(0)-[CAMModeDial:0x16f06760]>", 
    "<NSLayoutConstraint:0x18065ba0 CAMModeDial:0x16f06760.bottom == UIButton:0x180b5870'Cancel'.top>", 
    "<NSLayoutConstraint:0x180645f0 V:[UIButton:0x180b5870'Cancel']-(31)-| (Names: '|':CAMBottomBar:0x16f06100)>", 
    "<NSLayoutConstraint:0x180b6870 'UIView-Encapsulated-Layout-Height' V:[PLImagePickerCameraView:0x170f2600(0)]>", 
    "<NSLayoutConstraint:0x180b8780 CAMBottomBar:0x16f06100.height == PLImagePickerCameraView:0x170f2600.height>" 
) 

Will attempt to recover by breaking constraint 
<NSLayoutConstraint:0x16fa21f0 UIView:0x180afaa0.height == 0.454545*CAMModeDial:0x16f06760.height - 4.09091> 

Make a symbolic breakpoint at UIViewAlertForUnsatisfiableConstraints to catch this in the debugger. 
The methods in the UIConstraintBasedLayoutDebugging category on UIView listed in <UIKit/UIView.h> may also be helpful.

Я не в состоянии решить, что кто-то может помочь мне понять эти ошибки и и предложить, как идти о решении их?

Редактировать: - О поиске сети о CAMShutterButton, CAMModeDial, CAMBottomBar, PLImagePickerCameraView я нашел CAMShutterButton.h, CAMModeDial.h, CAMBottomBar.h классовые файлы в CameraKit.framework и PLImagePickerCameraView .h - файл класса в PhotoLibrary.framework. Которые являются частью частной инфраструктуры iOS 8, но я не использую ни один из них в своем приложении.

Answer 1

изменить приоритет ограничения

"<NSLayoutConstraint:0x18065b70 V:[CAMShutterButton:0x180bfbc0]-(0)-[CAMModeDial:0x16f06760]>" from Required(1000) to High(750)
