   Hi,
   I am using cocos2d-0.8-beta version.

   I am creating UISlider control as fallows

   UISlider * MySlider ;
   CGRect frame =CGRectMake(10, 370.0, 88 , 15.0);
   MySlider = [[UISlider alloc] initWithFrame:frame];
   and setting other properties of slider.

   MySlider.center=cpv(50 , 419);
   [self addChild:MySlider];

   this generates warning as : passing argument 1 of 'addChild' from distinct objective-c type and when I build application , app get crashed with log as

   Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** -[UISlider zOrder]: unrecognized selector sent to instance

   so could you help me adding UISlider control on the Layer?

   Correct me if I am wrong, but I don't think you can mix Cocoa and Cocos2D objects that way.

   What I did on my game (pretty hacky) is to add the Cocoa elements directly as subviews of the window.

   ob1 is correct, you can't add a UISlider or any other UIKit objects to a CocosNode.

   You can add it as a child of the OpenGL view, if you search the group for UIKit or click on the UIKit tag you will see some posts with an example of how to do this.

   Alternatively have a look at the AttachTest example. It shows how to add and remove the cocos2d OpenGL view in a UIKit view hierarchy.

   Finally, there is an example in the wiki that shows how to create a UIKit Layer that can be added into a Scene's node tree.
