The app added control widgets and crashed online。 SwiftU! static ControlWidgetConfigurationAdaptor._makeWidgetConfiguration(widget inputs:)

Set 3 controls to the AVCaptureSession and remove them all. The number of controls in the session is indeed 0, but the camera controls button still shows the previous 3 controls.

I added some AVCaptureControl, then removed all of it. The phenomenon is that AVCaptureSession controls are 0 in number, but the keys can still display the previous AvcaptureControls guard(_session.supportsControls) else return; for (AVCaptureControl *control in _session.controls) { [_session removeControl:control]; } @weakify(self); if (self.captureControl.zoom) { if (self.zoomScaleControl) { self.zoomScaleControl.enabled = false; [_session removeControl:self.zoomScaleControl]; } AVCaptureSlider *zoomSlider = [self.captureControl.zoom fetchCaptureSlider]; [zoomSlider setActionQueue:dispatch_get_main_queue() action:^(float zoomFactor) { @strongify(self); if ([self.dataOutputDelegate respondsToSelector:@selector(videoCaptureSession:tryChangeZoomScale:)]) { [self.dataOutputDelegate videoCaptureSession:self tryChangeZoomScale:zoomFactor]; } }]; self.zoomScaleControl = zoomSlider; } else { self.zoomScaleControl = nil; } if (self.captureControl.exposure) { if (self.exposureBiasControl) { self.exposureBiasControl.enabled = false; [_session removeControl:self.exposureBiasControl]; } AVCaptureSlider *exposureSlider = [self.captureControl.exposure fetchCaptureSlider]; [exposureSlider setActionQueue:dispatch_get_main_queue() action:^(float bias) { @strongify(self); if ([self.dataOutputDelegate respondsToSelector:@selector(videoCaptureSession:tryChangeExposureBias:)]) { [self.dataOutputDelegate videoCaptureSession:self tryChangeExposureBias:bias]; } }]; self.exposureBiasControl = exposureSlider; } else { self.exposureBiasControl = nil; } if (self.captureControl.len) { if (self.lenControl) { self.lenControl.enabled = false; [_session removeControl:self.lenControl]; } ORLenCaptureControlCustomModel *len = self.captureControl.len; AVCaptureIndexPicker *picker = [len fetchCaptureSlider]; [picker setActionQueue:dispatch_get_main_queue() action:^(NSInteger selectedIndex) { @strongify(self); if ([self.dataOutputDelegate respondsToSelector:@selector(videoCaptureSession:didChangeLenIndex:datas:)]) { [self.dataOutputDelegate videoCaptureSession:self didChangeLenIndex:selectedIndex datas:self.captureControl.len.indexDatas]; } }]; self.lenControl = picker; } else { self.lenControl = nil; } if ([_session canAddControl:self.zoomScaleControl]) { [_session addControl:self.zoomScaleControl]; } else { self.zoomScaleControl = nil; } if ([_session canAddControl:self.lenControl]) { [_session addControl:self.lenControl]; } else { self.lenControl = nil; } if ([_session canAddControl:self.exposureBiasControl]) { [_session addControl:self.exposureBiasControl]; } else { self.exposureBiasControl = nil; } [_session setControlsDelegate:self queue:GetCaptureControlQueue()];
