下面一段代码是小编给大家介绍的swift3.0键盘弹起遮挡输入框问题的解决方案代码解析，具体代码如下所示；
extension LoginViewController:UITextFieldDelegate{
func textFieldShouldReturn(_ textField: UITextField) -> Bool {
textField.resignFirstResponder()//键盘收回，view放下UIView.animate(withDuration: 0.4, animations: {
self.view.frame.origin.y = 0}
)return true}
func textFieldDidBeginEditing(_ textView:UITextField) {
//view弹起跟随键盘，高可根据自己定义UIView.animate(withDuration: 0.4, animations: {
self.view.frame.origin.y = -150}
)}
}
好了，代码到此结束，希望对大家有所帮助！
