解除uiimagepicker时崩溃

Question

这是crashlytics报告的问题。 加载图像选择器并关闭时，我得到了这个（我假设）。 我只有一次。 但这与图像选择器或导航控制器有关。 有人知道原因吗？

这样会加载更新图像选择器相机。

    UIImagePickerController *imagePickerController = [[UIImagePickerController alloc] init];
    imagePickerController.modalPresentationStyle = UIModalPresentationFullScreen;
    imagePickerController.sourceType = UIImagePickerControllerSourceTypeCamera;
    imagePickerController.delegate = self;
    if([UIApplication sharedApplication].statusBarOrientation == UIInterfaceOrientationLandscapeLeft)
    {
        [[UIDevice currentDevice]setValue:[NSNumber numberWithInteger:UIDeviceOrientationLandscapeRight] forKey:ORIENTATION_STRING];
    } else {
        [[UIDevice currentDevice]setValue:[NSNumber numberWithInteger:UIDeviceOrientationLandscapeLeft] forKey:ORIENTATION_STRING];
    }

    self.imagePickerController = imagePickerController;
    [self.navigationController presentViewController:self.imagePickerController animated:YES completion:nil];

对于其他源类型，我正在使用以下代码。

UIImagePickerController *imagePickerController = [[UIImagePickerController alloc] init];
imagePickerController.sourceType = sourceType;
imagePickerController.delegate = self;
popOver = [[UIPopoverController alloc] initWithContentViewController:imagePickerController];
self.imagePickerController = imagePickerController;
popOver.delegate = self;
CGRect popOverRect = sender.frame;
[popOver presentPopoverFromRect:popOverRect
                         inView:self.view
       permittedArrowDirections:UIPopoverArrowDirectionRight animated:YES];

Answer 1

将UIIMagePickerController添加到ContainerView。 然后查看

UIImagePickerController *picker = [[UIImagePickerController alloc] init];
picker.delegate = self;
picker.allowsEditing = YES;
picker.sourceType = UIImagePickerControllerSourceTypeCamera;
picker.mediaTypes = [[NSArray alloc] initWithObjects: (NSString *)   kUTTypeMovie, nil];

[self addChildViewController:picker] ;

[picker didMoveToParentViewController:self] ;

[self.view addSubview:picker.view] ;

同时删除pickercontroller做

[picker.view removeFromSuperview] ;
[picker removeFromParentViewController] ;
