我在imagepickerview controller的自定义叠加层中使用LLSimple相机。当我切换时，我添加了闪光灯开/关。我想把自动闪光功能。 Plz帮助我解决这个问题。

当你这样做：

self.imagePickerController = [[UIImagePickerController alloc] init]; 
    [self.imagePickerController setSourceType:UIImagePickerControllerSourceTypeCamera]; 
    [self.imagePickerController setCameraCaptureMode:UIImagePickerControllerCameraCaptureModePhoto]; 
........ 

明确提到

[imagePickerController setCameraFlashMode:UIImagePickerControllerCameraFlashModeOn]; 

如果你不那么相机默认为UIImagePickerControllerCameraFlashModeAuto 既然你已经实现了不处理这种情况下，逻辑，它仍然在UIImagePickerControllerCameraFlashModeAuto
