我已经尝试过UITextView 的解决方案在第一次单击时不显示 InputAccessoryView

我对具有inputAccessoryView的textView有疑问

我想通过它的inputAccessoryView调用[textView resignFirstResponder]，这样我就可以关闭键盘

并且inputAccessoryView上只有一个UIButton，点击该按钮将调用 IBAction 方法调用-(IBAction)closeKeyboard:(id)sender;

现在方法中的发送者是inputAccessoryView上的按钮，

问题是，

我怎样才能找出这个textView 的 inputAccessoryView 已被点击，

或者只是得到一个指向这个textView的指针，所以我可以打电话

[textView resignFirstResponder]??

You need to find the current first responder. If you have outlets to all your text views, you can ask each one in turn 

if ([textView1 isFirstResponder])
    [textView resignFirstResponder];

Though this may give you problems depending on your button (see here, but I haven't experienced this), if so use the editing property of the text view.
