Convert C# GraphicsPath drawing to Objective-C for iPad

I am porting some drawings from C# to the iPad. In C#, I have created a GraphicsPath using the constructor GraphicsPath(Point[], Byte[]), where the Point[] = the PathPoints array, and the Byte[] equals the PathTypes array. The PathPoints and PathTypes are stored in a database. Using the same data, I need to draw the figure exactly the same, pixel for pixel, on an iPad. The test figures are Chinese characters, which are fairly complex and need to be drawn with precision. I am attaching a file with the sample data -- column 1 and 2 are the x,y coordinates of each point, and column 3 is the PathType for each point.
