ios 8 uitextfield keyboard not appearing

//发现在iphone 6 and iPhone plus 上面键盘不出来。后来查了下原来要在模拟器里设置下

var inputText =  UITextField(frame: CGRectMake(, , self.view.bounds.size.width, ))
        inputText.text = ""
        inputText.delegate = self
        backView.addSubview(inputText)

     func textFieldShouldReturn(textField: UITextField) -> Bool {

        textField .resignFirstResponder()
        var b :Bool
       return true
    }

1. iOS Simulator -> Hardware -> Keyboard
2. Uncheck "Connect Hardware Keyboard"

选择iOS Simulatro 按照上面的步骤操作
