iPhone UIWebView becomeFirstResponder

Question

I have an UIWebView with an <input type="text"/> html element in it. I want to focus the input element in the html and show the keyboard on the iPhone programmatically, without tapping the screen.

I've tried the following:

set the focus from JavaScript (in this case the onFocus JS event will fire but the keyboard won't show up)
[webView becomeFirstresponder] (returns NO)
set the first subview of the webView to be the firstResponder (returns NO)
subclass UIWebView to return YES to canBecomeFirstResponder: (nothing happens)

I'm trying to find the solution since yesterday but I couldn't find it. Please help.

did you found some solution for this? The only way I found is to programmatically emulate a click on the WebView. But my app may be rejected because of this... :( — Dmitry, Aug 31 '12 at 10:27
Starting with iOS 6 you can use [keyboardDisplayRequiresUserAction](http://developer.apple.com/library/ios/#documentation/uikit/reference/UIWebView_Class/Reference/Reference.html) to do this. — catlan, Nov 06 '12 at 16:52
I don't know how you managed to create this problem but normally the becomeFirstResponder has to be used like I described it in my article: http://bcaccinolo.wordpress.com/2010/12/28/uitextfield-with-the-keyboard-automagically/ — Benoit Caccinolo, Dec 28 '10 at 10:50
Have you tried to put the focus method to the onload action of the web page? — Ondrej Rafaj, Feb 20 '13 at 15:50

In iOS6 or above, you have to set keyboardDisplayRequiresUserAction to NO first:

- (void)webViewDidFinishLoad:(UIWebView *)webView 
{
    webView.keyboardDisplayRequiresUserAction = NO;
    [webView stringByEvaluatingJavaScriptFromString:@"document.getElementById(\"theElementId\").setFocus();"]; 
}

Have you tried this? Don't forget to wire up the UIWebView's delegate connection, and ideally execute the javascript only when required.

- (void)webViewDidFinishLoad:(UIWebView *)webView {
    [webView stringByEvaluatingJavaScriptFromString:@"document.getElementById(\"theElementId\").setFocus();"]; 
}
