You can use the following method to evaluate javascript with a UIWebView object:

stringByEvaluatingJavaScriptFromString:

So in your case: If you have a UIWebView object called webview:

NSString *jsStat = @"document.getElementsByName('xyz')[0].click()";

[webView stringByEvaluatingJavaScriptFromString:jsStat];

The method returns the result of the script;

if you are making ios app using objective-c then you need to use UIWebView for this purpose, and load your html in the UIWebView and using its delegate methods check if button is clicked something like this 

- (BOOL)webView:(UIWebView*)webView shouldStartLoadWithRequest:(NSURLRequest*)request navigationType:(UIWebViewNavigationType)navigationType {



    if (navigationType == UIWebViewNavigationTypeFormSubmitted) {
 // form is submitted or button is clicked , perform your actions here
 }
return YES;

}
