iOS 隐藏百度地图SDK的百度LOGO

第一个思路：找到LOGO对应的UIIMageView,并将其隐藏hidden

// 隐藏百度地图Logo
    UIView *mView = _mapView.subviews.firstObject;
    for (id logoView in mView.subviews)
    {
        if ([logoView isKindOfClass:[UIImageView class]])
        {
            UIImageView *b_logo = (UIImageView*)logoView;
            b_logo.hidden = YES;
        }
    }

第二个思路：计算LOGO的尺寸，在将map的尺寸延伸到屏幕外，这样就看不到LOGO
