ios - 从相机切换到视频时 UIImagePickerController 崩溃

Question

切换到视频捕获模式后，在运行 iOS 13(真实设备)的 iPhone 上，UIImagePickerController 发生崩溃。 UIImagePickerController 的第二次演示中重现了崩溃。 iOS 13(真实设备)之前的版本不会重现崩溃。相机和麦克风使用描述键在使用 Xcode 11.0 构建的 Info.plist Test 应用程序中设置

步骤:

1. 当前 UIImagePickerController
2. 关闭UIImagePickerController
3. 当前 UIImagePickerController
4. 点击视频按钮 -> 崩溃

如果我设置videoQuality = UIImagePickerControllerQualityTypeHigh，则不会重现崩溃。但我需要 UIImagePickerControllerQualityTypeMedium。

@interface ViewController () < UINavigationControllerDelegate, UIImagePickerControllerDelegate>
@end

@implementation ViewController

#pragma mark - IBActions

- (IBAction)showPicker:(UIButton *)sender {
    UIImagePickerController *pickerController = [UIImagePickerController new];
    pickerController.sourceType = UIImagePickerControllerSourceTypeCamera;
    pickerController.mediaTypes = [UIImagePickerController availableMediaTypesForSourceType:UIImagePickerControllerSourceTypeCamera];
//    pickerController.videoQuality = UIImagePickerControllerQualityTypeHigh;
    pickerController.delegate = self;

    [self presentViewController:pickerController animated:YES completion:NULL];
}

#pragma mark - UIImagePickerControllerDelegate

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary<UIImagePickerControllerInfoKey, id> *)info {
    [self dismissViewControllerAnimated:YES completion:NULL];
}

- (void)imagePickerControllerDidCancel:(UIImagePickerController *)picker {
    [self dismissViewControllerAnimated:YES completion:NULL];
}

@end

在pickercontroller中设置视频质量

[pickerController setVideoQuality:UIImagePickerControllerQualityTypeIFrame1280x720];
