ios - Text inset for UITextField -

i have seen post text inset uitextfield? , still not able figure out.

i want uitextfield has 80.0 tall. want text 40.0 below top of uitextfield, 20.0 tall, leaving 20.0 below text padding. current code is.

let textbounds: cgrect = cgrect(x: 0, y: 40, width: self.width, height: 20) self.editingrectforbounds(textbounds) self.textrectforbounds(textbounds) 

the uitextfield subclassed , believe text has 30.0 padding above , below , 20.0 tall or vertically centered within uitextfield.

i have rewritten code use uitextfield subclass:

class mytextfield: uitextfield {     var textbounds: cgrect = cgrectzero      override init(frame: cgrect) {         super.init(frame: frame)         textbounds = cgrectmake(0, 40, self.frame.width, 20)     }      required init?(coder adecoder: nscoder) {         fatalerror("init(coder:) has not been implemented")     }      override func textrectforbounds(bounds: cgrect) -> cgrect {         return textbounds     }      override func editingrectforbounds(bounds: cgrect) -> cgrect {         return textbounds     }     } 

and added example of how might added view:

class viewcontroller: uiviewcontroller {      override func viewdidload() {         super.viewdidload()          let textfield = mytextfield(frame: cgrectmake(20, 64, 200, 50))         textfield.text = "hello world"           // show border visualize frame.         textfield.layer.bordercolor = uicolor.redcolor().cgcolor         textfield.layer.borderwidth = 1          view.addsubview(textfield)     }  } 

the uitextfield subclass can added view controller file or separate file. choice.
