Swift class doesn't like self.view.addSubview() -

i've built custom button , i'm trying put in class.

the code below throws error line "self.view.addsubview(button)" - used when code running under viewdidload.

any suggestions?

 class mybutton {     var buttonlabel:string     var buttonradius:cgfloat = 90     var button = uibutton.buttonwithtype(uibuttontype.system) uibutton      init(buttoncolour:cgcolorref, buttonlabel:string){         self.buttoncolour = buttoncolour         self.buttonlabel = buttonlabel     }      func drawbutton() {         button.frame = 100, 100, buttonradius * 2, buttonradius * 2)         button.layer.bordercolor = buttoncolour         button.settitle(buttonlabel, forstate: uicontrolstate.normal)         button.addtarget(self, action: "pressed:", forcontrolevents: uicontrolevents.touchupinside)         self.view.addsubview(button) // error: 'viewcontroller.mybutton' not have member named 'view' } 

you doing wrong. class not have view property. guess trying use view controller. every viewcontroller has property named view of type uiview looking for.

class myviewcontroller: uiviewcontroller {   var buttonlabel:string   var buttonradius:cgfloat = 90   var button = uibutton.buttonwithtype(uibuttontype.system) uibutton    init(buttoncolour:cgcolorref, buttonlabel:string){     self.buttoncolour = buttoncolour     self.buttonlabel = buttonlabel   }    func drawbutton() {     button.frame = 100, 100, buttonradius * 2, buttonradius * 2)     button.layer.bordercolor = buttoncolour     button.settitle(buttonlabel, forstate: uicontrolstate.normal)     button.addtarget(self, action: "pressed:", forcontrolevents: uicontrolevents.touchupinside)     self.view.addsubview(button) // error: 'viewcontroller.mybutton' not have member named 'view'   } }
