Getting the first responder... Unless you want to use the private [view firstResponder] this seems to be the only legal way. Or am I wrong?

FirstResponder.m

UIView *PSPDFFindFirstResponderBeneathView(UIView *view) {
    // Stop if e.g. we show an UIAlertView with a text field.
    if (UIApplication.sharedApplication.keyWindow != view.window) return nil;

    // Search recursively for first responder.
    for (UIView *childView in view.subviews) {
        if ([childView respondsToSelector:@selector(isFirstResponder)] && childView.isFirstResponder) return childView;
        UIView *result = PSPDFFindFirstResponderBeneathView(childView);
        if (result) return result;
    }
    return nil;
}

Never mind. This is much better: http://stackoverflow.com/questions/5029267/is-there-any-way-of-asking-an-ios-view-which-of-its-children-has-first-responder/14135456#14135456

@iottirubin your method seems a bit wasteful and ignores multiple windows. See the StackOverflow link above for a faster, more generic variant.

Hi @steipete,

Just wanted to make sure, the link you provided makes use of the "findFirstResponder" action.. Is this not a private API? I can only find mention of it in Apple's macOS documentation, not iOS.

Thx!
