XamForms.Controls.Calendar特殊日期文本模糊

Question

我在Xamarin.Forms项目中使用XamForms.Controls.Calendar，一切正常，但是在SpeacialDates属性的“文本”部分中输入的文本在iOS平台上显得模糊，如何解决？ / p>

DrawText功能ios也有相同的方法，尽管对此功能的深入研究无法解决模糊问题

   protected void DrawText(CGContext g, Pattern p, CGRect r)

        string fontname = Device.Idiom == TargetIdiom.Tablet ? "KohinoorTelugu-Light" : "GillSans-UltraBold";//GillSans-UltraBold
        var bounds = p.Text.StringSize(UIFont.FromName(fontname, p.TextSize));
        //"GillSans-UltraBold
        var al = (int)p.TextAlign;
        var x = r.X;
        if ((al & 2) == 2) // center
        {
            x = r.X + (int)Math.Round(r.Width / 2.0) - (int)Math.Round(bounds.Width / 2.0);
        }
        else if ((al & 4) == 4) // right
        {
