ios - Add UIView to Storyboard without a XIB file -

i attempting add uiview without nib file storyboard. have dragged uiview onto storyboard , changed it's class "jahreskalender" jahreskalender class follows:

 class jahreskalender: uiview {   override func drawrect(rect: cgrect) {      // drawing code      self.opaque = false      self.backgroundcolor = uicolor(red: 100, green: 1, blue: 5, alpha: 0)      let jahresview = uiimageview(image: uiimage(named: "calender.png"))      jahresview.frame = cgrect(x: 0, y: 0, width: 100, height: 100)      self.addsubview(jahresview)    } } 

when run app black rectangle have dragged uiview. need load xib file or can "jahreskalender" class programmaticall? looked everywhere can't find tutorials.

well, after more trial , error found mistake. need call init(coder adecoder: nscoder).

 required init(coder adecoder: nscoder) {         super.init(coder: adecoder)         self.opaque = false         } 

now works. tips!
