cocos creator 2.0.2后 游戏内截屏，native微信SDK分享代码：

public static wxShareScreenShot(sType: number) {

　　let node = new cc.Node();

　　node.parent = cc.director.getScene();

　　node.width = cc.view.getVisibleSize().width;

　　node.x = cc.view.getVisibleSize().height;

　　node.y = cc.view.getVisibleSize().width;

　　node.height = cc.view.getVisibleSize().height;

　　let camera = node.addComponent(cc.Camera);

　　camera.cullingMask = 0xffffffff;

　　let texture = new cc.RenderTexture();

　　texture.initWithSize(node.width, node.height);

　　camera.targetTexture = texture;

　　camera.render(null);

　　let data = texture.readPixels();

　　let width = texture.width;

　　let height = texture.height;

　　data = this.filpYImage(data, width, height)

　　let fileName = "result_share.jpg";

　　let fullPath = jsb.fileUtils.getWritablePath() + fileName;

　　if (jsb.fileUtils.isFileExist(fullPath)) {

　　　　jsb.fileUtils.removeFile(fullPath);

　　}

　　let success = jsb.saveImageData(data, width, height, fullPath);

　　camera.destroy();
