swift - Text reappearing in TextField after creating a new user -

// alright need clear text field logout button pressed. "inputtoolbar" variable using in messagesviewcontroller, logout button on screen.

@ibaction func logoutuser(sender: anyobject) {     let installation = pfinstallation.currentinstallation()     installation.setobject("", forkey: "user")     installation.saveinbackground()      pfuser.logout()      messagesviewcontroller.inputtoolbar.contentview.textview.resignfirstresponder()      //segue splash screen     self.navigationcontroller?.poptorootviewcontrolleranimated(true)  } 

with:

messagesviewcontroller.inputtoolbar.contentview.textview.resignfirstresponder() 

you're dismissing keyboard, not in view @ point.

to clear text view, need reset text property with:

messagesviewcontroller.inputtoolbar.contentview.textview.text = ""
