context.SelectFont ("Helvetica-Bold", textHeight, CGTextEncoding.MacRoman);
context.SetTextDrawingMode (CGTextDrawingMode.Invisible);

}示例2: MeasureStringWidth
// TODO: Cannot use NSAttributedString in iOS5, only iOS6+
// public static RectangleF MeasureString(SizeF sizeConstraint, string text, string fontName, float fontSize)
// {
// NSMutableDictionary dict = new NSMutableDictionary();
// dict.Add(NSAttributedString.FontAttributeName, NSFont.FromFontName(fontName, fontSize));
// NSString nsstr = new NSString(text);
// RectangleF rect = nsstr.BoundingRectWithSize(sizeConstraint, NSStringDrawingOptions.UsesFontLeading | NSStringDrawingOptions.UsesLineFragmentOrigin, dict);
// return rect;
// }
public static float MeasureStringWidth(CGContext context, string text, string fontName, float fontSize)

}示例3: DrawTextAtPoint
// Draws the specified text starting at x,y of the specified height to the context.
protected void DrawTextAtPoint (CGContext context, float x, float y, string text, int textHeight)
{
// configure font
context.SelectFont ("Helvetica-Bold", textHeight, CGTextEncoding.MacRoman);
// set it to fill in our text, don't just outline
context.SetTextDrawingMode (CGTextDrawingMode.Fill);
// call showTextAtPoint
context.ShowTextAtPoint (x, y, text, text.Length);
}示例4: ShowTextAtPoint
