如何以编程方式打开iPhone手机键盘？

Question

我不想拨打电话号码。我只是想以编程方式打开手机键盘。

我该怎么做？

Answer 1

我认为您可以添加UITextField并将其隐藏，然后调用becomeFirstResponder：

var textField : UITextField //Create and set hidden to true
textField.keyboardType = UIKeyboardType.PhonePad //keyboardType
textField.hidden = true

//To Fire keyboard
textField.becomeFirstResponder()

Answer 2

更新@Hossam Ghareb的回答

var textField : UITextField = UITextField(frame: CGRect(x: 0, y: 0, width: 100, height: 100)) //Create and set hidden to true

textField.keyboardType = UIKeyboardType.PhonePad //keyboardType
textField.hidden = true

//To Fire keyboard
textField.becomeFirstResponder()

//Add to your view 
self.view.addSubview(textField)
