I have faced the same issue in iOS10, too. Here is my problem:

And I solved this problem by:

 self.pickerView.backgroundColor = COLOR_DEDEDE;
 self.pickerView.showsSelectionIndicator = YES;
    for (UIView *view in self.pickerView.subviews) {
        if (view.bounds.size.height < 2.0f && view.backgroundColor == nil) {
            view.backgroundColor = PICK_Line_COLOR; // line color
        }
    }

Note:

this code mush be called after method:[self.view addSubview:pickeView];

The final result：

it works in my project. Hope it helps to you.
