    cgcolorspaceref colorspace = Cgcolorspacecreatedevicergb ();  
    Cgcolorref COLORREF = Cgcolorcreate (ColorSpace, (cgfloat[)) {0, 0, 0, 1});  
    [Box.actionButton.layer setbordercolor:colorref];//border Color  
    //The second method is as follows:  
    //_testbutton.layer.bordercolor=[ Uicolor Graycolor]. Cgcolor;
