javascript - preventing keyboard drops while loading in iOS -

in ios app, need focus on text field, based on user's previous interactions. focusing using javascript well, follows (in viewdidfinshload method)

if (![focuselement isequaltostring:@""]) {     // make keyboard freely appear without user intervention     [webview setkeyboarddisplayrequiresuseraction:no];     // first lose previous focus , focus on     // clicked element     nsstring *jstofocus = [nsstring stringwithformat:                            @"document.activeelement.blur();document.getelementbyid(\'%s\').focus();",                            [focuselement utf8string]];      // javascript focuses on input     [webview stringbyevaluatingjavascriptfromstring:jstofocus]; 

this works well. problem when page loads further frames/javascripts, key board drops down , reappears couple of times every new load. guess happening due earlier

   [webview setkeyboarddisplayrequiresuseraction:no]; 

is there (better) way , more importantly, keep keyboard displayed once focused on input element, until user dismisses it.

thanks in advance. nikhil

as work-around problem, introduced property web view, called it

    @property bool iskeyboardshown; 

by default set no , long keyboad not shown allow loading further frames/elements. however, once focus on desired element set yes , forcibly stop further loading. in short viewshouldstartload... method looks like

- (bool)webview:(uiwebview *)webview shouldstartloadwithrequest: (nsurlrequest *)request                                                  navigationtype:  (uiwebviewnavigationtype)navigationtype {      if (self.iskeyboardshown)          return no;   ... further code ... 

then introduced keyboard notifications

// set keyboard notifications [[nsnotificationcenter defaultcenter] addobserver: self                                          selector: @selector(keyboardwillbehidden:)                                              name: uikeyboardwillhidenotification                                            object: nil]; 

and method

- (void) keyboardwillbehidden : (nsnotification *) keyboardhidenotice {         self.iskeyboardshown = no; } 

so, overall idea focus on element -> show keyboard -> stop further loading long keyboard -> reset loading permissions on keyboard dismissal

this works fine, have further problem:

if user finishes inputing text , presses search or go key on keyboard, because keyboard still , iskeyboardshown property yes, webview not proceed search unless user taps on lens (dismissing keyboard).

is there way detect search key-press event? note, input not uisearchbar: (
