我刚刚从 iOS 5.1.1 升级到 6.0，当它尝试显示一个带有 imagePickerViewController 作为其 contentVC 的弹出框以允许用户从 photoLibrary 中选择图像或视频时，以下代码路径与 SIGTRAP 一起崩溃。

它在 5.1.1 上运行良好。这几天我一直在解决这个问题，但没有任何进展。有没有人对此有处理？iOS6.0 有替代方法吗？如果需要，我可以添加更多代码...

我可以使用以下线路捕获图像和视频：

[self presentViewController:self.imagePickerViewController.imagePickerController animated:YES completion:NULL];

这是用户触摸 UIButton 后完整调用的方法。

- (void)showImagePicker:(UIImagePickerControllerSourceType)sourceType mediaType:(NSString *)mediaType
{
    if (self.capturedMovies.count > 0)
        [self.capturedMovies removeAllObjects];

    if ([UIImagePickerController isSourceTypeAvailable:sourceType])
    {
        [self.imagePickerViewController setupImagePicker:sourceType mediaType:mediaType];

        if (sourceType == UIImagePickerControllerSourceTypeCamera) { // WORKS
            [self presentViewController:self.imagePickerViewController.imagePickerController animated:YES completion:NULL];
        }
        else if (sourceType == UIImagePickerControllerSourceTypePhotoLibrary) { 
        //else if ([mediaType isEqualToString:(NSString *)kUTTypeMovie] || [mediaType isEqualToString:(NSString *)kUTTypeImage]) {

            if (!self.moviePickerPopoverController) {
                self.moviePickerPopoverController = [[UIPopoverController alloc] initWithContentViewController:self.imagePickerViewController.imagePickerController];
            }

            UIView *uiViewObject = self.mediaTitleTextField;

            CGFloat xLocation = uiViewObject.frame.origin.x;
            CGFloat yLocation = uiViewObject.frame.origin.y;

            CGFloat width = uiViewObject.bounds.size.width;
            CGFloat height = uiViewObject.bounds.size.height;

            // CRASHES HERE!!!
            [self.moviePickerPopoverController presentPopoverFromRect:CGRectMake(xLocation, yLocation, width, height)
                                                               inView:self.view
                                             permittedArrowDirections:UIPopoverArrowDirectionAny
                                                             animated:YES];
        }
    }
}

这是代码窗口中弹出的内容：

线程 1：第 3 行上的信号 SIGTRAP：

这是调试器的回溯：

另外，我应该触摸调试器上的 go 按钮......它揭示了有问题的代码：

在此处输入图像描述

*** Terminating app due to uncaught exception
'UIApplicationInvalidInterfaceOrientation',
 reason: 'Supported orientations has no common orientation
 with the application, and shouldAutorotate is returning YES'
