ios - Center a UITextField -


i trying center uitextfield , code :

import spritekit import gameplaykit import uikit  class gamescene: skscene {  var sampletextfield = uitextfield()  override func didmove(to view: skview) {      let mainview = uiview(frame: cgrect(x: 0, y: 0, width: self.size.width, height: self.size.height))      view.addsubview(mainview)      sampletextfield = uitextfield(frame: cgrect(origin: mainview.center, size: cgsize(width: 200, height: 20)))      sampletextfield.placeholder = "enter text here"     sampletextfield.font = uifont.systemfont(ofsize: 15)     sampletextfield.borderstyle = uitextborderstyle.roundedrect     sampletextfield.autocorrectiontype = uitextautocorrectiontype.no     sampletextfield.keyboardtype = uikeyboardtype.default     sampletextfield.returnkeytype = uireturnkeytype.done     sampletextfield.clearbuttonmode = uitextfieldviewmode.whileediting;     sampletextfield.contentverticalalignment = uicontrolcontentverticalalignment.center      mainview.addsubview(sampletextfield)     }  }

but uitextfield doesn't appear because think outside of screen, how center in screen?

try using center method:-

sampletextfield.center = cgpoint(x: value1, y: value2)
