我在我的应用程序中访问默认摄像头。有时它显示黑屏。这个问题的解决方案是什么?。
if ([UIImagePickerController isSourceTypeAvailable:
UIImagePickerControllerSourceTypeCamera])
{
imgPicker = [[UIImagePickerController alloc] init];
imgPicker.delegate = self;
imgPicker.sourceType = UIImagePickerControllerSourceTypeCamera;
// imagePicker.mediaTypes = [NSArray arrayWithObjects:(NSString *) kUTTypeImage, nil];
imgPicker.allowsEditing = NO;
imgPicker.showsCameraControls = NO;
cameraView.backgroundColor = [UIColor clearColor];
imgPicker.cameraOverlayView = cameraView;
[self presentModalViewController:imgPicker animated:YES];
}
