Question

I have seen this question, but the question is how to know which textView is the first responder? This question looked promising to figure out the first responder, but it turns out that it calls private APIs. Is there any way to hide the keyboard or to figure out the first responder as the-one-who-has-the-keyboard?

Answer 1

It’s easy:

[[[UIApplication sharedApplication] keyWindow] endEditing:YES];

take a look at UIView Class Reference.
