As I understod that you want a Uiview child that respond to 3 register: 1- double tap to select to be rotated by +45 degree when the button in the controller is taped. 2- pinch to scale the canvas view 3- pan to move the selected canvas in its super view. in the SFSviewcontroller i will instantiate to 3 instance from SFS canvas and add the two small instance as subviews to the C instance and add the c instance to the main view of the controller. the SFSView controller should has a button on its view that rotate the selected view. in SFSView there will be a gray line drawn between the center of its child view of type SFScanvas in drawrect so it will be redrawn with each redrawing of the main view according to their position. I have experience in developing games and interactive controller for ios and i teach game development for iphone course i have worked on an interactive book app i used much more advanced approach and i did view animation like your app and layer level animation and i have a good knowledge in core animation library. i will deliver you a prototype in the first iteration within two days to validate your requirements. then i will apply any modification you mention within the next two days second iteration. [login to view URL] this is an app with layer level animation Best regards
