如何删除uiimagepickercontroller的范围滑块?

已经回答了 HERE

func subviews(_ view: UIView) -> [UIView] {
    return view.subviews + view.subviews.flatMap { subviews($0) }
}

let myViews = subviews(imagePickerController.view)
for view in myViews {
    if view is UISlider {
        view.alpha = 0.0
    }
}

找到解决办法了。
回答 Here 也。

showsCameraControls 应该设置在 UIImageViewController 已加载。
这意味着您可以在自定义uiimageviewcontroller的初始化中执行此操作。

- (instancetype)init {
    if (self = [super init]) {
        self.showsCameraControls = false;

        self.sourceType = UIImagePickerControllerSourceTypeCamera;
        self.delegate = self;
    }
    return self;
}
