Question

这是一个非常愚蠢的堆栈跟踪，因为looking around，我唯一能想到的是iPhone 6s用户试图3D触摸某些东西，而我的手势识别器（某处，我不知道）知道哪一个，因为它不告诉我哪一行甚至哪个控制器）不知道如何处理它？我没有添加任何3D触摸手势识别器，也没有在任何地方实现3D触摸交互。

我已经在这个版本中针对iOS 8，但我没有iPhone 6s进行测试，因此无法真正重现它。

关于可能导致它的原因的思考，如何缩小何处/什么以及如何重现，以及如何处理异常？

Answer 1

PUPhotoGridViewController（在UIImagePickerController中使用）是一个简单的UICollectionViewController，您可以为未实现的方法编写扩展名。

extension UICollectionViewController: UIViewControllerPreviewingDelegate {
    public func previewingContext(previewingContext: UIViewControllerPreviewing, viewControllerForLocation location: CGPoint) -> UIViewController? {
        return nil;
    }

    public func previewingContext(previewingContext: UIViewControllerPreviewing, commitViewController viewControllerToCommit: UIViewController) {

    }
}

Answer 2

您是否在应用中的某处使用了UIImagePickerController？它和3D Touch有一个已知问题：UIImagePickerController crashing on force touch?

强制触摸UIImagePickerController中的照片似乎会使任何应用程序崩溃。我想我们必须等到Apple修复此问题。

感谢@Antigp'answer！

这是OC版本：

标题

@interface UICollectionViewController (FixCrash) <UIViewControllerPreviewingDelegate>
- (UIViewController *)previewingContext:(id<UIViewControllerPreviewing>)previewingContext viewControllerForLocation:(CGPoint)location;
- (void)previewingContext:(id<UIViewControllerPreviewing>)previewingContext
     commitViewController:(UIViewController *)viewControllerToCommit;
@end

实施

@implementation UICollectionViewController (FixCrash)
- (UIViewController *)previewingContext:(id<UIViewControllerPreviewing>)previewingContext viewControllerForLocation:(CGPoint)location {
    return nil;
}
- (void)previewingContext:(id<UIViewControllerPreviewing>)previewingContext
         commitViewController:(UIViewController *)viewControllerToCommit {
    return;
}
@end
