使用UIImagePickerController拍摄视频和picker'view不能全屏显示吗？

Question

I want to take video in my app running iOS7, then I use UIImagePickerController to do it. But I find the picker's view not full-screen, appears 2 black view both on left and right? How to resize for full-screen. Code like this:

  picker.mediaTypes = [NSArray arrayWithObjects:(NSString *)kUTTypeMovie, nil];
  picker.videoQuality = UIImagePickerControllerQualityTypeIFrame1280x720;

I tried to set videoQuality with UIImagePickerControllerQualityType640x480, then appears 2 black view both on top and bottom.

And when present picker(on iOS7), how to change status bar style? Thanks.

Answer 1

you can use pickerViewcontroller Delegate to customer it,for example

- (void)navigationController:(UINavigationController *)navigationController willShowViewController:(UIViewController *)viewController animated:(BOOL)animated
{
    UIImagePickerController * picker  = (UIImagePickerController *) navigationController;
    if (picker.sourceType != UIImagePickerControllerSourceTypeCamera) {
        [viewController.navigationItem setTitle:@"请选择照片"];
        viewController.navigationItem.leftBarButtonItem = ....
        viewController.navigationItem.rightBarButtonItem =  ...     
        }
    }

}

Answer 2

CGSize screenSize       = CGSizeMake(320, 708);
float cameraAspectRatio = 4.0 / 3.0;
float imageWidth        = floorf(screenSize.width * cameraAspectRatio);
float scale             = ceilf((screenSize.height / imageWidth) * 10.0) / 10.0;
myImagePickerController.cameraViewTransform   = CGAffineTransformMakeScale(scale, scale);
