Question

在切换到视频捕获模式后，使用ios 13真实设备的iPhone上的UIImagePickerController崩溃。崩溃在UIImagePickerController的第二次演示中重现。崩溃不会在ios 13（真实设备）之前的版本上重现。相机和麦克风的使用描述键在Xcode 11.0内置的Info.plist Test应用程序中设置

步骤：

当前的UIImagePickerController 关闭UIImagePickerController 目前的UIImagePickerController 点按视频按钮->崩溃如果我设置videoQuality = UIImagePickerControllerQualityTypeHigh，则崩溃不会重现。但是我需要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

“ NSInvalidArgumentException”，原因：“ ***-[AVCaptureDevice setActiveColorSpace：]不支持-使用activeFormat.supportedColorSpaces”

Answer 1

在pickercontroller中设置视频质量

[pickerController setVideoQuality:UIImagePickerControllerQualityTypeIFrame1280x720];

从相机切换到视频时，UIImagePickerController崩溃
