Shape Export to Objective C
With as3swf you can automatically generate Objective-C source code (Core Graphics, Quartz) from SWF Shapes, to reuse those shapes in your iPhone projects. The as3swf CoreGraphics shape exporter generates ready-to-use Objective-C header (.h) and class (.m) files (UIView subclass).
The following example is a simple AIR application that loads a SWF and exports all contained shapes to Objective-C source code. Source files are written to a folder “as3swf” on the Desktop, named “Shape[x]View.h” and “Shape[x]View.m” (where [x] is the Shape ID).
package
{
import flash.display.Sprite;
import flash.events.Event;
import flash.filesystem.File;
import flash.filesystem.FileMode;
import flash.filesystem.FileStream;
import flash.net.URLLoader;
import flash.net.URLLoaderDataFormat;
import flash.net.URLRequest;
import flash.utils.ByteArray;
import com.codeazur.as3swf.SWF;
import com.codeazur.as3swf.tags.ITag;
import com.codeazur.as3swf.tags.TagDefineShape;
import com.codeazur.as3swf.exporters.CoreGraphicsShapeExportDocumentHandler;
public class Test extends Sprite
{
public function Test()
{
var request:URLRequest = new URLRequest("any.swf");
var loader:URLLoader = new URLLoader();
loader.dataFormat = URLLoaderDataFormat.BINARY;
loader.addEventListener(Event.COMPLETE, completeHandler);
loader.load(request);
}
private function completeHandler(e:Event):void {
var swf:SWF = new SWF(URLLoader(e.target).data as ByteArray);
for (var i:uint = 0; i < swf.tags.length; i++) {
var tag:ITag = swf.tags[i];
if (tag is TagDefineShape) {
var defineShape:TagDefineShape = tag as TagDefineShape;
var docHandler:CoreGraphicsShapeExportDocumentHandler =
new CoreGraphicsShapeExportDocumentHandler(
"Shape" + defineShape.shapeId + "View",
"Claus Wahlers",
"côdeazur brasil"
);
defineShape.export(docHandler);
writeSource(docHandler);
}
}
}
private function writeSource(docHandler:CoreGraphicsShapeExportDocumentHandler):void {
var fileName:String = "as3swf" + File.separator + docHandler.className;
var h:File = File.desktopDirectory.resolvePath(fileName + ".h");
var m:File = File.desktopDirectory.resolvePath(fileName + ".m");
var stream:FileStream = new FileStream();
stream.open(h, FileMode.WRITE);
stream.writeUTFBytes(docHandler.h);
stream.close();
stream.open(m, FileMode.WRITE);
stream.writeUTFBytes(docHandler.m);
stream.close();
}
}
}The interesting part here is the completeHandler. The SWF is parsed by as3swf into an internal object model. The code then iterates over all tags, and, for each DefineShape tag, exports the respective shape and writes the resulting class files to the file system. While the tag’s export function executes, it calls back functions defined in the document handler (see IShapeExportDocumentHandler and CoreGraphicsShapeExportDocumentHandler), which generate the Objective-C code.
Here’s a simple demo of a SWF whose shapes get exported to Objective-C classes using the example code above:
This SWF contains only one shape:
