ios - 在移动到下一个 Controller Swift iOS 之前错误隐藏键盘

Question

我想在移动到下一个 Controller 之前隐藏键盘。同时在 viewWillDisapear 中实现 self.view.enditing(true) 。但是keybard不隐藏怎么隐藏呢？

func textFieldDidBeginEditing(_ textField: UITextField) {

        if textField == tagTxt{
            self.view.endEditing(true)
            textField.resignFirstResponder()
            let interstControlle = self.storyboard?.instantiateViewController(withIdentifier: "InterestViewController") as! InterestViewController
            interstControlle.PContId = "InterestViewController"
            interstControlle.delegate = self
            if tagsID.count > 0{
                interstControlle.PTagsID = tagsID
            }
            self.navigationController?.pushViewController(interstControlle, animated: true)
        }
    }

Answer 1

使用这个:

-(BOOL)textFieldShouldBeginEditing:(UITextField *)textField {
   if textField == tagTxt{
     return NO;
   }
   return YES;
}

swift 3:

func textFieldShouldBeginEditing(_ textField: UITextField) -> Bool {
     if textField == tagTxt{
        return false
     }
     return true
}
